When the coefficients of the formulas in a chemical equation have been adjusted to satisfy the law of of , the equation is said to be balanced.

When the coefficients of the formulas in a chemical equation have been adjusted to satisfy the law of conservation of mass, the equation is said to be balanced. This means that the number of atoms of each element in the reactants side of the equation equals the number of atoms of that same element in the products side of the equation.

Here are the steps to balance a chemical equation:

1. Write down the unbalanced equation. 'Reactants --> Products'

2. Count the atoms of each element in the reactants and the products.

3. Use coefficients to balance the equation. Coefficients are small whole numbers that are placed in front of the formulas in a chemical equation in order to balance it.

4. Double-check to make sure that you have the same number and type of atoms on the both sides of the equation.

5. If not, adjust the coefficients as needed.

6. Once the equation is balanced, make sure that the coefficients are in the lowest possible ratio.

Remember, you can only change the coefficients in front of compounds to balance a chemical equation, you cannot change the subscripts inside a chemical formula.
