Chemicals Together in an Effort to be Greener Essay

Alhamdulillah, first of all, I would like to thank Allah as I could finish my chemistry assignment with the title of Chemistry in your daily life. I would like to express my deepest appreciation to all those that help me, contribute their suggestion and opinion in doing this assignment from the beginning until finish because, without their help, I might have little problem in this research. Even though a few problems occurred when doing the assignment but luckily it can be settled down. With a lot of effort, finally, this task can be sent to our lecturer before the submission date as well. Furthermore, a special thanks to my lecturer chemistry, Dr. Musfiroh bt Jani that deliver this assignment and explain clearly how to do this assignment with the concept of chemistry and how to applied it in daily life to make sure we can score chemistry and understand the true meaning of chemistry. We can do this without her as she guides and fix our mistakes from starting of this assignment and want to improve the new one so this assignment can be completely finished and get a better result. Next, big thanks go to other Chemistry lecturers that teach me and guide me as long as I was a student and will make sure I can understand properly what is chemistry, why we need to learn chemistry and the important thing is we learn this to understand the knowledge to apply in real life, not because the exam. They also teach me how to produce a good assignment and report. Moreover, many thanks to my parents that support me from for with their contribution especially by providing money to me as I need to find references and they also help me in give an idea to make sure I can finish my assignment. Last but not least, thanks to my friends that always support and stick with me when hard and happy in this life and for those who are directly and indirectly support and help me with the assignment. Have you ever wondered why ice melts a water evaporates? Why do leaves turn colors in the fall, and how does a battery generate electricity? Why does keeping foods cold slow their spoilage, and how do our bodies use food to maintain life? There are a lot of nature and phenomena life that happens around us that involved chemistry. Have you wondered what is chemistry? And what chemistry can do in our life? How chemistry can be important and relates to our life? All the question can be answered in Chemistry as chemistry provides really important understanding and how it can be applying in our daily life as a human. That is the reason why we need to study chemistry. By studying chemistry, we can learn to use powerful language and ideas to describe what happened because chemistry is universal science that covered all the process around us include matter and also the process of humans. Chemistry? What crossed in your mine about chemistry? Either about chemistry with friends, chemistry in doing the same things, chemistry in a relationship for couples or anything else. Yes, that’s all true but in science actually, chemistry is a study of matter, properties, and its behavior. Chemistry also provides an understanding background of matter which it can be divided by atoms, molecules, gas. Atoms are smallest particles of elements that exist surrounding us. It is made of three tiny particles that called subatomic particles which is protons, neutrons, and electrons. The center of the atom, called nucleus is made up of protons and neutrons. Every single thing in this world is made up of matter include our bodies. Chemistry is relating to everything in life and it is a large branch that needed by everyone. Not only doctor, but the dentist, pharmacist, nurse, geologist, and others need chemistry too. Chemistry can be divided into five main branches which are very wide in the application of life. The first is analytical chemistry which discusses uses qualitative and quantitative observation to identify and measure the physical and chemical properties of substances. In fact, all chemistry is analytical chemistry. Secondly is physical chemistry. As we know, physical chemistry is discussed physics combine with chemistry. It’s about how matter can interact with energy. The important things in this topics are thermodynamics and quantum mechanics. The third branch of chemistry is organic chemistry which studies in compounds that contains carbon element. Carbon has many unique properties that allow it to form complex chemical bonds and very large molecules. Inorganic chemistry studies a materials such gases and metals that do not contain carbon as part of their make up. Last but not least is biochemistry is study of chemical processes that occur between organisms. Try to imagine the world without chemistry.

Radon Chemical and Physical Properties

Radon Chemical and Physical Properties Atomic Number: 86 Symbol: Rn Atomic Weight: 222.0176 Discovery: Fredrich Ernst Dorn 1898 or 1900 (Germany), discovered the element and called it radium emanation. Ramsay and Gray isolated the element in 1908 and named it niton. Electron Configuration: [Xe] 4f14 5d10 6s2 6p6 Word Origin: from radium. Radon was once called niton, from the Latin word nitens, which means shining Isotopes: At least 34 isotopes of radon are known ranging from Rn-195 to Rn-228. There are no stable isotopes of radon. The isotope radon-222 is the most stable isotope and called thoron and emanates naturally from thorium. Thoron is an alpha-emitter with a half-life of 3.8232 days. Radon-219 is called actinon and emanates from actinium. It is an alpha-emitter with a half-life of 3.96 sec. Properties: Radon has a melting point of -71Â °C, boiling point of -61.8 Â °C, gas density of 9.73 g/l, specific gravity of the liquid state of 4.4 at -62Â °C, specific gravity of the solid state of 4, usually with a valence of 0 (it does form some compounds, however, such as radon fluoride). Radon is a colorless gas at normal temperatures. It is also the heaviest of the gases. When it is cooled below its freezing point it displays a brilliant phosphorescence. The phosphorescence is yellow as the temperature is lowered, becoming orange-red at the temperature of liquid air. Inhalation of radon presents a health risk. Radon build-up is a health consideration when working with radium, thorium, or actinium. It is also a potential issue in uranium mines. Sources: It is estimated that each square mile of soil to a depth of 6 inches contains approximately 1 g of radium, which releases radon to the atmosphere. The average concentration of radon is about 1 sextillion parts of air. Radon naturally occurs in some spring waters. Element Classification: Inert Gas Physical Data Density (g/cc): 4.4 ( -62Â °C) Melting Point (K): 202 Boiling Point (K): 211.4 Appearance: heavy radioactive gas Specific Heat (20Â °C J/g mol): 0.094 Evaporation Heat (kJ/mol): 18.1 First Ionizing Energy (kJ/mol): 1036.5 Lattice Structure: Face-Centered Cubic CAS Registry Number: 10043-92-2 Trivia Ernest Rutherford is sometimes credited with the discovery of radon. He actually discovered the alpha particle radiation given off by radon.Radon became the official name for element 86 in 1923. The IUPAC chose radon from the names radon (Rn), thoron (Tn) and actinon (An). The other two names are given to isotopes of radon. Thoron is Rn-220 and actinon became Rn-219.Other suggested names for radon included radium emanation, niton, extadio, exthorio, exactinio, akton, radeon, thoreon and actineon.The U.S. Environmental Protection Agency lists radon as the second highest cause of lung cancer.

How to Get Through Family Holidays and Survive

How to Get Through Family Holidays and Survive Heading home for the first time in four months? If so, you might be surprised at how much your perspective has changed. Now that you’ve been on your own at college, going back to your parent’s house can feel much different than when you were in high school. Even though it hasn’t been very long, you’ve already begun to create your own habits. While it’s important to be self-sufficient, your family might not be used to the more confident version of you. And, if you’re not careful, your new-found independence may ruffle feathers. By following these guidelines, you’ll be more likely to have a pleasant experience when you go home for the holidays. Prepare Your Sales Pitch Everyone, including your nosey Aunt Dorothy, is going to want to know all about your experience at college. Don’t expect that they’ll avoid the most uncomfortable questions – How are your grades? Do you have a girlfriend/boyfriend? When are you going to get a job? To make it easier on yourself, prepare answers to those questions before you even get home. It should be something simple, easy-to-remember, and cover all the questions that you’re sure to get. Practice Smooth Topic Transitioning Don’t want to talk about the love interest you brought last year? Are you avoiding the inevitable discussion about your grade in English? Practice smooth topic transitioning. The truth is, most people don’t want to hear about your embarrassing details. It’s more likely that they’d rather talk about themselves or something less controversial. For example: Relative: What ever happened to that rash you had last month? Did you ever find out where you picked it up? You: I actually too busy with my internship at Microsoft. Did you know that Bill Gates really does give out cash to his employees at Christmas time? Relative: Really? How much did you get? Another embarrassing crisis averted! Eat Healthy When they talk about the Freshman 15, what they don’t tell you is that holiday eating accounts for about 25% of your weight gain. When you head home to delicious homemade pie and all the turkey you can eat, it can be tempting to eat like you’ve been on a deserted island for the last few months. Instead, try to eat a few regular meals each day and browse lightly on the holiday goodies. Remember, you can always pick up a small cooler for a couple of bucks and bring some of those delicious treats back to your dorm later. Shop Early Especially if you and your family members are close, you don’t want to spend the few precious weeks leading up to Christmas hanging around by yourself in the mall. Instead, plan on getting the bulk of your holiday shopping done before you head out of town. That way, you can enjoy the time you have with your family doing other fun things, not just stressing out about when and where to buy all your presents. Manage Conflict Even the best families have issues that are sensitive. Whether it’s money-related, job-related, or just a simple personality conflict, nothing ruins the holidays more than fights that could have been avoided. In order to keep the peace this holiday season, here is a list of increasingly helpful ways to deal with a difficult situation or topic. Attempt to transition the conversation. Take a deep breath and count to 5. Respond with, â€Å"I understand how you feel. Maybe we can talk about this later.† Excuse yourself to the bathroom. Stay there until you feel confident you can discuss the topic rationally and without anger or aggression. Take a walk around the block. Write a note expressing your feelings in the most positive way possible. Remember: You Are the Guest Your parents are allowing you to stay, probably free-of-charge in their home. It’s your responsibility, as their guest, to follow their rules. That may mean inconvenience for you such as not being able to sleep in the same room as your significant other, not being able to smoke, or refraining from certain language – but it’s worth it to show your family you appreciate their hospitality. Are there other important ways that you get through your holidays back at home? Share your thoughts in the comment section below!

Regional Econmic Essay Example | Topics and Well Written Essays - 500 words

Regional Econmic - Essay Example The economic implications should be apparent. Protection of these spaces leads to the conservation of scenic landscapes ideal for outdoor recreation especially in this period where people are finding ways to escape the city life. The presence of wildlife presents a more interesting experience for the individual and may make him willing to pay a fee for access to such open spaces. Open spaces then presents an opportunity to gain revenue thru small fees charged from campers and hikers. One might argue that open spaces would generate little revenue which does not justify the amount used to purchase. Ranches and lands for suburban developments do not come cheap. While it is recognized that the amount of purchase can indeed be large, it should also be noted that revenue generation of open spaces is not confined to access fees and the like. Open and natural areas can have multiple uses-benefits. While providing scenic views, the area can have some of its portions available for sustainable livestock foraging. Revenue can be generated by renting pasture for livestock grazing and presents opportunity for livestock producers who have little capital to own ranches for themselves.

ECON Research Paper Example | Topics and Well Written Essays - 1000 words

ECON - Research Paper Example Hypothetically, the relationship is that with a budget deficit, there is likelihood that the government may finance this deficit through printing of more money and pumping it into the economy. This leads to more money into the economy leading to inflation. Since this printing of money is not going concordant with production of goods and services. This concept is popular with developing countries where financial markets are not well developed to finance the deficit or when the public lacks enough confidence in the government of the day to invest in the government’s debt, or when the central bank is not independent and therefore easily manipulated by the government to finance its debts. Data pointing on the relationship between budget deficit and inflation are hard to come by since different countries give varying statistics. Some show a direct relationship while some do not hence this research. This research will use the statistics of the United States budget deficit and inflat ion and United Kingdom deficit and inflation. UK and US financials The united kingdom and the united states are considered to be relatively economically stable countries with independent central banks and relatively stable financial markets. This means the central bank is under no influence by the political class and financial markets may be used to finance budget deficits. This leaves the budget deficit and inflation as independent entities and it would therefore be interesting to see what other relationship there may be between the two concepts. Financial data of these two countries will be used in this paper. Budget Deficit or Surplus Data US Surplus or Deficit data The above graph shows the US deficit and surplus over a period of 20 years. The fluctuation over the years may indicate change in political environment and shift in policies. UK Surplus or Deficit data The above graph shows similar data over the same period of time but of the UK. The figures show huge variations betwe en the two countries. It may seem the two are exact opposites of each other. For the rise of one over a given period, a fall of another within the same period is reflected. Inflation Data US inflation rates The inflation data chosen is of the same period of years, 1982-2012. The figures are also fluctuating over the years, this too may be due to changing monetary policies, and political era shifts. UK inflation rates The inflation figures between US and the UK are not as varied as the budget deficit figures. The figures seem to go in tandem with each other. This may be due to economic common factors that lead to such. The common factors may be global, bearing that the US and the UK control a significant portion of the world’s economy. Budget deficit/inflation figures US Budget deficit/Inflation The US budget deficit and inflation figures show a relationship between the two. A rise in one shows a rise in the other. This may indicate lack of full independence of the central ban k. However, lagged the relationship may be, there is a relationship. UK budget deficit/Inflation The UK budget deficit and inflation figures show a more lagged relationship. The relationship between the two graphs is not reflective of an active relationship between the two figures. It may indicate a very independent central bank. However, it is important to consider the difference in the economic operation between the two c

Challenges of Raising a Disabled Child Essay Example for Free

Challenges of Raising a Disabled Child Essay Caring for a child with a disability can be challenging due to parenting responsibilities and the difficulties they encounter when interacting with an often unreceptive environment. Consequently, parents can be at increased risk for excessive levels of personal distress which in turn can adversely affect the well being of the child and the entire family unit (Plant Sanders, 2007). Parents of children with disabilities can be at an increased risk for psychosocial distress (Parish, Rose, Grinstein-Weiss, Richman Andrews, 2008; Plant Sanders, 2007). The parenting responsibilities for parents of children with disabilities often require a significant amount of time to complete, can be physically demanding, can disrupt family and social relationships, and can adversely affect caregiver employment (Brannen Heflinger, 2006; Seller Heller, 1997). Perhaps as a consequence of these additional impacts, family caregivers of children with disabilities can be at increased risk to experience depression, physical health problems, and decreased quality of life (Feldman, et al. , 2007; Ones, Yilmaz, Cetinkaya, Calgar, 2002). The added challenges of caring for a child with a disability may lead to more stress and greater physical and emotional health risks for parents and their families (e. g. , increased conflict with spouse; Murphy, Christian, Caplin Young, 2006) compared to families without a child with a disability (Feldman et al. , 2007). This topic is particularly personal for me because I know first hand the psychological affects and challenges that a handicap child could have on parents, family members, and friends. My son was two months when I notice that something just wasn’t right with him. I noticed him favoring one side instead of looking straight ahead. I mentioned my concerns to our family doctor. His doctor didn’t see it as a problem. She said to just continue to watch him. Two months passed and still no change, so at his next appointment I expressed my concern again. I insisted that she run tests on my son immediately. I knew something seemed different; I just couldn’t put my finger on it. I had already had two other boys so something just didn’t sit right with me. The doctor sent my son to be tested at University of Maryland Hospital and my son was diagnosed with Hydrocephalus Dandywalker Malformation with Palsy. He had to have surgery at six months to have a shunt placement to drain the water from his brain. I was devastated. My husband and I went through several defense mechanisms. The first I believe was denial. We didn’t want to face the fact that something was wrong with our child, our baby. He seemed so perfect when he was born just a few months ago. We went through repression, rationalization and intellectualization. We couldn’t wrap our minds around the fact that our child would be different from other children. Nobody wants to believe that something is wrong with their child. I felt a little embarrassed for fear of what people might think about our child or what someone would say. So many things raced around my mind. We wanted to blame the doctors; maybe they did something wrong in my prenatal care. I went over in my mind again and again of every little thing I did when pregnant to ensure that I had did everything I was supposed to do. I didn’t drink, smoke or do drugs. What happened? We tried to search our family history genetics. We just came up empty. My husband and I became depressed, frustrated, and angry. I felt helpless about my son’s condition. I wasn’t sure what to do. Finally, I began to investigate my son’s condition. I read all I could get my hands on. I searched for schools and other medical resources to help me address my son’s needs. In the back of my mind I was still trying to make sense of the fact that my son had a developmental and neurological problem that would affect him for the rest of his life. I wondered what restrictions we would face now and in the future. I still wasn’t sure if I could cope with his lack of development neurologically, physically, mentally or emotionally. I began to question God. I wondered why me. I wasn’t sure if I would have to stop working. I wondered how we as a family would work together to stay a family. I had so many questions, but no answers. I prayed asking God for help and guidance. Later, I began to realize that I had to be strong. I had to accept what the reality was with my son and his disability. It hasn’t been easy. We faced many financial problems, medical issues, several hospitalizations for my son, divorce; daycare issues especially since my son needed twenty four hour daycare. Day care is very expensive as well as diapers and wipes for disabled children. Insurance covers some things but not enough. A person has to be making next to nothing in order to get any assistance from the government; we needed assistance regardless of what we made monetary. I would have never known what disabled families went through to get their voice heard and children’s needs assisted unless I had to face these great challenges myself. So much goes into raising a child with disabilities. There are many variables that factor into taking care of a disabled child. Financial hardships are another important factor that influences parents’ wellbeing. In general families with children with disabilities experience much higher expenditures than other families (Newacheck and Kim, 2005) found that, on average, the total annual health care expenditures for children with disabilities were more than three times as much compared to children without disabilities. The financial strain incurred by families of children with disabilities is likely due to increased expenses related to the child’s needs as well as loss of employment or inability to work because of parenting responsibilities (Murphy et al. , 2006; Parish et al. 2008; Worcester et al. , 2008). Inability to engage in employment can also lead to feelings of isolation, a lack of fulfillment and low self-esteem (Shearn Todd, 2000). Families of children with disabilities often report feeling isolated from the community (Freedman Boyer, 2000; Worcester et al. , 2008). What I’ve learned from researching the challenges of raising a child with disabilities; as well as being a parent of a disabled child is that there is still so much more to be done. There is still research that hasn’t been touched regarding parents and their disable children. We the parents have to be the voices for our disable children. We have to be better informed about what our disabled children rights are. We have to be willing and ready to fight on behalf of our disable children. Parents and state officials have to work to get better laws passed to accommodate disabled children. Disabled children need better health care programs, better schools; a place for them to be themselves. Parents need a place to relax and not have to worry about dirty looks that people who don’t have disabled children give them. Parents shouldn’t have to feel ashamed that they have disabled children. We shouldn’t be looked down upon because our children are different. Our children shouldn’t be bullied or treated like they are worthless. Our children are special. They deserve the best that we can help them to achieve in life. They deserve a chance like the rest of us. We’ve got to come together and help each other to provide a better life for all! The questions we should ask researchers to study are many. One could be what’s being done to assist parents with disabled children? Are there programs to assist parents in child care for disabled children? Normal daycare centers are for infants through 12 years of age. As of today my disabled son is 16 years old and there’s really no day care for children his age. Another question is why do they go according to parents’ income in order to assist with social security disability? A parent shouldn’t have to be jobless in order to obtain assistance from social security disability. Yet a person who walks into social security disability and say my back hurt or that they have a condition can obtain money; work the system while the truly disabled suffer. There are so many people working the disability system and really aren’t disabled. We have to help the programs we have for our disabled children actually help the disabled children. In conclusion caring for a child with a disability can be challenging, but many of these challenges are likely due to a lack of necessary environmental supports. Future research should expand on these findings and policy makers, scientists and providers should give particular attention to the environmental support needs of parents in order to create policies and interventions that are more family centered.
