Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure the same number of each type of atom on both sides of the equation.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

What is the general format for writing chemical equations?

Back

The general format is: reactants → products.

Front

What is the significance of coefficients in a chemical equation?

Back

Coefficients indicate the number of molecules or moles of each substance involved in the reaction.

Front

What does it mean to say a chemical equation is balanced?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides, reflecting the conservation of mass.
