Chemistry HN Unit 7 Vocab

Stoichiometry

The study of relationships between the amount of chemicals used and the amount of chemicals produced in a balanced reaction.

limiting reactant

Determines how much of the products can be produced in a chemical reaction.

mole ratio

Corelates two different chemicals in a balanced equation, for Stoichiometric calculations.

STP conditions

For all gas reactants and products, they must be at O Celsius, 273 K, 1 atm & 101.3 kPa.

theoretical yield

The amount of product we expect to produce based on the stoichiometric calculations.

excess reactant

When one reactant is more than is needed based on Stoichiometry and is left over at the end of the reaction.

percent yield

A ratio of the experimental or actual yield to the theoretical yield.

mole

The Avogadro Number of particles, or one ____ , is the key to all stoichiometry problems.

actual yield

The amount of product obtained at the end of a reaction in a lab experiment.

molar volume

When calculating the amount of gas produced or consumed in a reaction, we use the equality 1 mole = 22.4 L.
