Stoichiometry Concepts and Applications

Front

What is stoichiometry?

Back

Stoichiometry is the branch of chemistry that deals with the mass relationships of elements in compounds and the mass relationships among reactants and products in chemical reactions.

How do you calculate percent yield?

Back

Percent yield is calculated using the formula: (actual yield / theoretical yield) x 100%.

What happens when the limiting reactant is completely used in a reaction?

Back

The reaction stops when the limiting reactant is completely used.

Front

What is composition stoichiometry?

Back

Composition stoichiometry is the study of the mass relationships of elements in compounds.

Front

How do you determine the limiting reactant?

Back

To determine the limiting reactant, calculate the number of moles of each reactant available.

Front

What is the theoretical yield?

Back

The theoretical yield is the maximum amount of product that can be produced from a given amount of reactants.

Front

What is a limiting reactant?

Back

A limiting reactant is the reactant that is completely consumed in a chemical reaction, limiting the amount of product formed.

Front

What is an excess reactant?

Back

An excess reactant is a reactant that remains after the limiting reactant is completely consumed.

Front

What is the mole ratio in a chemical reaction?

Back

The mole ratio is the ratio of moles of one substance to the moles of another substance in a balanced chemical equation.

Front

How do you convert grams to moles?

Back

To convert grams to moles, divide the mass of the substance by its molar mass.
