Chemistry open book paper Photochemical smog is a mixture of primary and secondary pollutants; primary pollutants are those released directly into the atmosphere from human activities such as burning fuels. ... The main secondary pollutants are: • Ozone (O ) • Nitrogen dioxide (NO ) • Hydrogen peroxide (H O ) • Peroxyacetyl nitrate (PAN) • Nitric acid (HNO ) • Partially oxidised hydrocarbons Primary and Secondary pollutants produced by motor vehicles Fuels contain compounds of nitrogen (NOx) these are oxidised when the fuel is bur...
Carbon monoxide is a very dangerous gas. It has no odor, no taste, and is indivisible. Carbon monoxide happens from incomplete combustion of woods, gas, charcoal, propane, natural gas, and oil. It is found mostly in low levels in the air. Like for example one place would be the fireplace inside a...
The goal of this research was to determine the water quality by observing the characteristics, chemistry and animals that live in Dug Run. ... After recollecting all this information about the Water Chemistry, and the species of macro-invertebrates and fishes that live in the Dug Run, it's easier for us to determine and have a better understanding of the water quality, and therefore meet the goal of this project. ...
Chemistry In this lab activity we did the process of esterification, making a ester from an acid, and a alcohol. The products of this reaction or process are an ester and water. An ester is a chemical made to give aroma or flavoring to a substance. We took different acids like, glacial acetic ...
How do Sutures Dissolve? Did you know that a catgut suture has been around since 150 A.D.. But what so modern doctors use for sutures with the right compatibility, strength, and ability to dissolve using the right biochemistry materials. Doctors use a Synthetic Biodegradable polymer for all the c...

My element is Zinc (Zn) which is an active element. Zinc today is very useful, its used for many things like stopping iron from rusting; its also good for the human body, it helps us grow but it also gives you side effects if you get to much of it. Zinc is used today for galvanizing, galvanize is u...
A cid rain is formed when certain gases dissolve in rainwater to form acids. Acid rain by definition in the Chemistry book states: "Rainwater that has become excessively acidic because of absorption of pollutant oxides, notably SO3, produced by human activities"(1). There are airborne pol...
Before the Industrial Revolution, man based most of their technology on the burning of natural gasses or fossil fuels. The constant breakdown of these elements over time has released large amounts of harmful chemicals and gasses into the atmosphere. Global warming is just one of the many results ...
Social Background and Present Status Patient X is a Haitian born immigrant, who has been a legal citizen of the United States for 27 years. She is the mother of four children all of whom were born in Haiti as well. Two years prior to the crash, Patient X had filed for the remaining members of he...
"What is Acid Rain?" You hear about it all the time in the news and it is very important to the earth's ecosystem. In simple terms, acid rain is rain that is more acidic than normal. All objects in nature have a certain level of acidity but acid rain has too much acid in it. Acid rain is a compli...
Acid rain is rain that is polluted. The pollutants go up to the atmosphere and when it rains, it brings the pollution down with it. Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. When these gases mix with moisture it can make rain, snow, hail, or even fog. The scientific te...
In an attempt to show a degree of understanding of this reaction, the above diagram has been constructed and split into four steps to illustrate how butan-1-ol' functional group reacted with acetic anhydride to produce butyl acetate. This has been described in three stages however this reaction happ...
Car accidents can prove to be fatal. However, with the proper safety measures, fatality can be avoided. Seatbelts can save your life, as well as airbags. An airbag is a big that undergoes a chemical reaction to burst out and causes a stop in motion, pillowing you into it. Airbags are complex, and a necessity to life. ...
Scientists are talking about technology that would provide a well-rounded understanding the wide range of undersea processes including: plate shifting, volcanic activity, current patterns, and the physics and chemistry of marine habitats. ...
Introduction What is acid rain? Why is it omnipotent? What are the effects of the acid rain? Are there any prevention acts against it? These are just some of the questions that come to one's mind if the topic of acid rain ever comes up. So what is it? Acid Rain is a rain or any other form of prec...
Abstract The goal of the soil project was to separate, purify, identify and quantify the four compounds that were present in an unknown soil sample. We were told that two of the compounds were organic and the other two were inorganic. We were given a list of all possible compounds, which we examined and used to create a procedure based on techniques we studied and practiced throughout the course that would allow us to perform both qualitative and quantitative analyses of our soil sample. We started our separation using vacuum filtration, first with ethyl acetate, and then water. This gave us ...
ACID RAIN ACID RAIN "Statues dissolving and guns rusting, children choking and soil becoming poisoned, trees withering, rocks blackening. And the trout float belly-up" (Pawlick 184). These are some of the disastrous effects caused by acid rain. In North America this cancer eats into the very hea...
