Stoichiometry

Stoichiometry is a branch in chemistry that essentially deals with the "math" of chemistry. For instance, take photosynthesis. 6H2O + 6CO2 = C6H12O6 + 6O2. That's the stoichiometric formula for photosynthesis. 6 water molecules plus 6 carbon dioxide molecules makes one sugar molecules with an extra 6 oxygen molecules. The plant uses the sugar molecules for itself and gets rid of the oxygen molecules for us to breathe. We take the oxygen and the carbon dioxide, and we breathe out the carbon dioxide for the plants to take. It's a big circle. That formula for photosynthesis is basic stoichiometry. The chemistry and math go together. For a simple math problem, there is a simple stoichiometric problem. For a hard math problem comes a hard stoichiometric problem.
