Front

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

Back

Theoretical yield

Front

Define 'theoretical yield'.

Back

The maximum amount of product that can be produced from a given amount of reactant.

Front

What is a balanced chemical equation?

Back

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

Front

How do you calculate the mole ratio from a balanced equation?

Back

By comparing the coefficients of the reactants and products.

Front

What is the significance of mole ratios in chemical reactions?

Back

They allow chemists to predict the amounts of reactants and products involved.

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 calculated maximum.
