Study Notes
Stoichiometry
- Stoichiometry is founded on the Law of Conservation of Mass.
- Stoichiometry allows the calculation of the amount of products that will be produced in a chemical reaction if the amounts of the reactants are known.
- In the chemical equation CH4 + 2 O2 → CO2 + 2 H2O, the number 2 represents two molecules of O2.
- The chemical equation CH4 + 2 O2 → CO2 + 2 H2O represents the reaction between methane and Oxygen gas that produces Carbon Dioxide and water.
- Stoichiometry illustrates that the relationship between reactants and products is quantifiable and follows the Law of Conservation of Mass.
- The Law of Conservation of Mass is the foundation of stoichiometry and is used to calculate the amount of reactants and products involved in a chemical reaction.
- The amount of the other reactants and products involved in the reaction can be calculated if the amount of one reactant is known.
