Stoichiometry

how much can a reaction produce?

Stoichiometry: mass and quantity relationships among reactants and products in a chemical reaction
How to solve stoichiometry:
Check the units given
Determine the mole ratio
Use the mole ratio to calculate moles
Use molar mass to calculate grams
Other methods you can use:
List what you know
Set up the problem
Estimate and calculate
Reaction stoichiometry compares the mass and quantity of substances in a chemical equation. Composition stoichiometry describes the relationship among the elements within a substance Stoichiometry problems can be solved with conversions factors created from mole ratios, molar masses, density, and avogadro’s number. Excess reactant: reactant that will not be used up in a reaction that goes to completion Limiting reactant: reactant that is consumed first in a reaction that foes to completion Theoretical yield: calculate maxium amount of product possible from a given amount of reactant Actual yield: measured amount of product actually produced from a given amount of reactant Precent yield: ratio of actual yield to theoretical yield, multiplied by100.

how can stoichiometry be used?

There are many ways to use stoichiometry is used with cars which is used as air bags.
