A balanced chemical reaction satisfies the law of conservation of matter. Subscripts and coefficients determine thenumber of atoms and moleculesin a chemical equation. The part of the chemical formula that shows the ratio of a molecule’s atoms and determines its chemical identity are known as subscripts.

How do you balance an equation with a coefficient of 2?
Placing a coefficient of 2 before the product, however, will balance out the equation and is written as N 2 + O 2 鈥?gt; 2NO. In another example, once again involving atoms of nitrogen and oxygen, coefficients need to be added to both sides of the following unbalanced equation: N 2 + O 2 鈥?gt; N 2 O 3.
What is a balanced chemical equation?
A balanced chemical equation is a reaction in which the number of atoms in a reaction is equal on both the reactant and the product side for each element. A balanced chemical reaction satisfies the law of conservation of matter.
