with permanganate were determined. Every chemical reaction ranges from hours to femtoseconds to occur. The rate of a chemical reaction can be determined by assessing the change in either the reactant or product in a given time or point (Connors, 1990). It is important to take account of the stoichiometric ratios of each component, regardless as to which compound is chosen to determine the rate. The study of the rates of chemical reactions is called Chemical Kinetics (Soustelle, 2011). The following

In 1986, Polysar Limited was Canada’s largest chemical company with $1.8 billion in annual sales. Based in Sarnia, Ontario, Polysar was the world’s largest producer of synthetic rubber and latex and a major producer of basic petrochemicals and fuel products. The results for NASA Rubber division for the first nine months were not as good as expected. Sales volume was up and feedstock costs were down resulting in a gross margin that was better than budget. The fixed costs of the butyl rubber plant

SCH4U – The Chemistry of Covalent Bonding Date_____________________ Orbital Hybridization One of the most influential chemistry books ever written was The Nature of the Chemical Bond by Linus Pauling (1901-1994). Published in 1939, Pauling was awarded the Nobel Prize in 1954. Pauling received a second Nobel Prize for peace in 1962. Pauling made tremendous contributions to the field of chemistry, and was an outspoken activist against war and nuclear weapons. If you consider the energy

Jacinta Houng Comparing the Solubility of Chemicals in Water “Water is known as the “universal solvent” because so many different substances dissolve in it and we rely on this for many of our daily needs.” Introduction: Water is known as the ‘universal solvent’ as it is capable of dissolving a variety of different substances and dissolves more substances than any other liquid. However the ability to be soluble depends on a substances polarity and bonding. This then contributes to the various ways

process of digestion to break down and extrapolate the nutrients from our food to maintain and fuel our bodies. In order to perform digestion our bodies use enzymes, which are biological catalysts. They are made of proteins that responsible for the chemical reactions essential to sustaining life. Enzymes have three major characteristics: increase the rate of reaction, are substrate specific and lower the energy barrier it takes to for reactants to occur. Enzymes can also react differently under certain

HANDY-DANDY GUIDE TO WRITING A REACTION PAPER If you were to ask 10 people, "How do I write a Reaction Paper?" you'd probably get 10 different responses. No one seems to know exactly how to do one, yet almost everyone is assigned one at some point in his or her academic career. Here is a guide to what faculty are usually "looking for" in a well-written reaction paper. Remember, however, that every faculty member is different: some will want you to spend more time "analyzing" or "evaluating" the

plants use a process called photosynthesis. This process is when the plant uses the sunlight to make sugar molecules. Also during this process the plants gain solar energy. The solar energy trap will produce chemical reactions that will require water and carbon dioxide. The carbohydrates (chemical reaction from water and carbon) are consumer by animals. Soon a chain reaction begins: plants- animals eat the plants- animals eat the animals that eat the plants. The sunlight energy will move, grow and reproduce
