Front

What is a mole ratio in a chemical reaction?

Back

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

Front

What is the difference between actual yield and theoretical yield?

Back

Actual yield is the amount of product obtained from a reaction, while theoretical yield is the maximum possible amount.
