Chemical Reactions Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. Later, in the Seventeenth...

One Of Life¡s Great Proteins ¡V Hemoglobin Introduction Hemoglobin is a protein, which is one of the four basic biological molecules of life. Proteins have many functions and are versatile molecules. They are important for building and repairing cells and tissues and also as enzymes that are...

Year 11 Chemistry Unit 1 POLYETHENE-ain't it choice! word count : 1131 Polyethene also known as polyethylene or polythene, was the first of the polymers to be discovered. Polyethene is a polymer produced by reacting oxygen and ethene, in this reaction the small ethene molecules attach t...

Acid rain is rain that is more acidic than normal. Acid rain is a complicated problem. Primarily caused by air pollution, acid rain's spread and damage involve weather, chemistry, soil, and the life cycles of plants and animals on the land and in lakes and streams. This form of air pollution is ...

Sterling Lake Introduction We were interested in the biotic and a biotic factor in the aquatic environments of Sterling Lake in Lake County, IL. We examined water chemistry by using the Hach kit spectrometer to measure the chemical components dissolved in water. We tested a particular form of ...

MTBE Methyl Tertiary Butyl Ether. The word sounds like it's foreign. It might even sound like it is out of that nerd in highschool's chemistry book, but it is becoming as common as wildfires in Redding. Until about seven years ago, when it was first introduced into our lives, many ...

People often look at the world with a jaded eye, seeing and addressing problems, without any knowledge to back them up. To apply this idea to the world we live in, one can look at three basic environmental problems the world faces today; acid rain, ozone depletion, and global warming. Each of t...

For many years now, scientists have researched and test the affects of air pollution. It has already been proven that pollution and the chemical substances affect a person's health and well being. There are a lot of things pollute the air, including ourselves and what we do. Pollution is basi...

A Review of Oxidative Stress and Antioxidants Introduction Oxidants such as super oxide, a free radical form of oxygen gas, hydrogen peroxide, and free radical hydroxide are molecules that can commence chain reactions in a cell and cause damage along the way. A free radical is any molecule with...

In this paper I will describe the molecular structure and the chemical properties of water. Also I will discuss the importance of water to living organisms and the effects of acid rain on our environment. Water, as a molecule is a bent molecule and this characteristic makes it a very polar. W...

Electron Pair Repulsion Theory: The electron pair repulsion theory states that the electron pairs in the valence energy level of an atom repel each other, and therefore are arranged as far apart as possible. For example, H2O: Due to this theory, different molecules with different...
