Stoichiometry of Chemical Reactions

Dr. Stephen Lukacs (October 2020)

Everything you've learned prior is about compounds and their stability. Now, we get into the meat of chemistry through chemical reactions and the proper amounts and proportions required for good reactions.

Balancing Reactions

(October 2020) Reactions are the conversion of reactants or starting materials into final products. Balancing reactions ensure that whatever quantities enter the reaction process also exit. Just like cooking or mixing drinks, all things have a proper proportion and balancing reactions are simply those proper proportions to the natural mixture of atoms and molecules.

Stoichiometry of Chemical Reactions

(October 2020) Stoichiometry is simply the ratios of reactants and products in the balanced reaction. But those ratios can be extended to include very complex multi-step chemical conversions to answer very practical quantitative problems.
