Balancing Equations

Front

What is a balanced chemical equation?

Back

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

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.

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.

Front

What is a coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a chemical formula to indicate how many molecules or moles of that substance are involved in the reaction.

What does it mean to 'balance' an equation?

Back

Balancing an equation means adjusting the coefficients so that the number of atoms of each element is the same on both sides of the equation.

Front

What is the first step in balancing a chemical equation?

Back

The first step is to write the unbalanced equation and count the number of atoms of each element on both sides.
