Front

What is the term for the maximum amount of product that could be obtained in a chemical reaction?

Back

Theoretical yield

Front

Define mole ratio.

Back

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

Front

What is a balanced chemical equation?

Back

An equation that has the same number of atoms of each element on both sides.

Front

What is the difference between theoretical yield and actual yield?

Back

Theoretical yield is the maximum amount of product expected, while actual yield is the amount actually obtained.
