Chemistry - Stoichiometry Flashcards
Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in a chemical reaction. The molecular formula shows the exact number and types of atoms in a single molecule of a compound. It differs from the empirical formula, which shows only the simplest ratio.
What is Stoichiometry
the branch of chemistry that tells us the relationship between amounts of rectants and products in a chemical reaction

explain the limiting reactant | when carring out chemical reactions its common for chemists to use and excessive amount of one or more of the reactants in order to increase the yeild of products |
what is the yeild of a product | the amount of a product formed in a chemical reaction |
what is theoretical yeild | the yeild calculated from the equation,it assumes the reaction is 100% efficent |
what is actual yield | the yield that is obtained in practice |
how to get percentage yield | actual yeild / theoretical yeild x 100 |
