Substances that enter into a chemical reaction are known as.. \n\n reactants?\n\n catalysts? \n\n products? \n\n protons?

reactants...catalysts help a reaction by speeding it up (usually)...products are the end result of reactions...protons just aren't the right answer

You could also try\nwww.rxlist.com\nthey shurely describe the mode of action\n\nFor chemical structures try\nwww.wikipedia.org\nthey should cover a lot of the substances, I guess.

From which perspective?  Reactions or Transport or both?\n\nLike, if you want to do reactions, you can give a rate law for absorption and reaction on a catalyst.  Solve for the PBR size necessary to give X % conversion of the reactants.\n\nFrom a mass transport standpoint, perhaps look at the mass flux of reactant to a catalyst surface?

The sign there is a chemical reaction is the fact there is heat being released.  Evidently, the reactant have more energy, because they are able to release that energy in the form of heat.

Chemicals used in the reaction is important. What is the pKa of the reactant? Research on which buffer and what its pH buffering region is important, because it should cover the pKa region of the chemicals used. Once knowing which buffer to make, we can take a buffer by making a mixture that have a weak acid with its salt of conjugate base, or weak base with its conjugate acid. It should be noted that here buffer solutions are presented in terms of the Brønsted-Lowry notion of acids and bases.

these electrons are the ones that participate in chemical reactions, ie formation of bonds

Yes they react, for example:\n\nCH3COOCH2CH3 + HCOOH  <==> HCOOCH2CH3 + CH3COOH

Any chemical reaction is based on a flow of energy.  Provide more energy and you can then make the reaction faster, as the energy is more abundant to allow the compounds to react, and each molecule will then get to the proper energy level required to react at a faster rate.

A pure substance has a formula or symbol so we know exactly what atoms are in it in what proportion. \n\nIn a mixture there can be any material in any proportion.\n\nIn a solution, a type of mixture, there is one substance dissolved in another so that they are all mixed and anywhere we take a sample it will be the same.

Acids & bases is pretty easy to understand. You could probably find quite a bit of stuff too, about their properties, indicators, things they're used for, all that stuff. Or you could try energy. It may be a little harder, but you could go on forever about energy. What types of energy there are (thermal kinetic, mechanical kinetic, radient, gravitational potential, electrical potential, chemical potential), how energy changes between forms, pahses changes in matter (because of energy), on and on and on. Hope that helps.

Hydrogen and Oxygen are elements and H20 and H2O2 are examples of compounds formed with these elements. An atom is an element , two or more of them are a compound \n\nExocytosis is the process by which a cell releases large biomolecules through its membrane such as enzymes, peptide hormones and antibodies\nFive steps are involved in exocytosis:\nVesicle tethering  \nVesicle docking  \nVesicle priming  \nVesicle fusion

Collision Theory - A theory that suggests that chemical reactions occur when reacting particles collide with each other with sufficient energy.\n\nOrganic Chemistry - There are many hundreds of thousands of organic chemicals. Anything containing carbon atoms can be considered to be organic. The proteins that make up our hair, skin, and muscles, DNA and RNA, the foods we eat, the clothes we wear and the medicines we take are all organic chemicals.\n\nThey are given the name organic because it was once thought that the only difference between inorganic and organic chemicals was that organic chemicals seemed only to come from living things, but this was dismissed in the early 1800's when 'chemists' made known organic compounds (like urea) from known inorganic compounds. It was later realised that all organic chemicals contain carbon, this is the only distinguishing feature between inorganic and organic chemicals.\n\nRate of Reactions - There are 5 factors that affect the rate of reaction, which are Physical state of reactants, concentration, temperature, catalysts and light.
