Chemicals Found Everywhere
Hidden Dangers Everyday humans are exposed to toxic chemicals and the majority of these people are unaware of the fact. Until viewing websites with regard to chemicals in our society, I too was unaware of how often an individual comes into contact with these toxins. There were three sites that were explored and they were quite informational. The first website Banned Elsewhere, Compounds Still Used in U.S. by Marla Cone, explains to readers about

Chemical Engineering
CHEMICAL ENGINEERING Chemical engineering is the branch of engineering that deals with the application of physical science (e.g. chemistry and physics), with mathematics, to the process of converting raw materials into valuable forms. As well as producing useful materials, chemical engineering is also concerned with pioneering valuable new materials and techniques; an important form of research and development. It largely involves the design and maintenance of chemical processes for large-scale manufacture. As a matter of

Harmful Chemicals That Are in Our Enviroment
Harmful Chemicals That Are In Our Enviroment According many scientific researchers, our entire population has been dowsed with chemicals. There are several aspects of this dowsing that should concern us. First, and foremost, many of these chemicals are suspected to have damaging health effects on humans, as well as, other life forms. Second, most of these chemicals have only recently been produced so the environment is clearly changing and being challenged by these newcomers.

Easily Made Silicon-Based Chemicals from Sand
Word Count 504 Easily Made Silicon-based Chemicals from Sand I believe this new process of creating silicon-based chemicals from sand will revolutionize the industry by decreasing costs and increasing productivity. University of Michigan Professor and materials scientist, Richard Laine, discovered a relatively non-toxic and inexpensive way of producing a many different kinds of silicon-based chemicals. This Process uses sand or rice hull ash and antifreeze to create needed chemicals while helping to decrease costs

Chemical Equilibrium
CHEMICAL EQUILIBRIUM Reversible reactions and dynamic equilibrium Ammonia (NH3) is an important industrial chemical that is used in the manufacture of fertilisers. It is manufactured by reacting hydrogen with nitrogen. The reaction is said to be reversible and the conversion of reactants to products is never complete. N2 + 3H2 2NH3 A reversible reaction is a reaction which can take place in either direction When the concentrations of the reactants and product have become constant,

Chemical Reactions - Sodium Hydroxide
Chemical Reactions- Sodium Hydroxide A chemical reaction is a change where two or more substances are changed into a new substance. You can identify a chemical reaction by colour change, effervescence (bubbles), when light or heat given off, and the change is usually irreversible. There are 6 main types of chemical reactions- combustion (often called burning), synthesis, decomposition, neutralization, single replacement and double replacement. A combustion reaction is a reaction with oxygen, and heat is

Chemicals
A chemical substance is a material with a definite chemical composition. It is a concept that became firmly established in the late eighteenth century after work by the chemist Joseph Proust on the composition of some pure chemical compounds such as basic copper carbonate.[1] He deduced that: "All samples of a compound have the same composition; that is, all samples have the same proportions, by mass, of the elements present in the compound". This became

Chemical Reactions of Copper Compounds
Chemical Reaction of copper compounds Introduction: In this experiment, the objective was to conduct a series of chemical reactions that contain copper or copper compounds. That is to say that the products of each chemical reaction were used in the next reaction. The process starts with a solid copper wire dissolved in nitric acid and the end product is copper powder. The product which was used from the previous reaction is the limiting. In the

Determining Optimum Environmental and Chemical Effects on Enzyme Kinetics
Abstract Enzymes, fundamental proteins that catalyze reactions by lowering activation energy, operate under kinetic principle and can react slower or faster with different ph and temperature levels. By finding this optimum temperature and pH through a process of spectrophotometery we can understand how many of the enzymes in our body function in different environments. I will examine a set of pH ranges and temperature ranges to find which one has the fastest reaction rate due

Harper Chemical Company
HARPER CHEMICAL COMPANY The Harper Chemical Company (HCC) was a medium sized producer of industrial chemicals, which sold its products primarily to customers in the paper industries and the paint industries. In 1980, HCC diversified into the production of a mineral called Dominite. By acquiring the Dominite activities, HCC hoped it would yield at least 15% return on investment after taxes. In early 1980, the HCC board of directors authorised the construction of a processing
