Quizplus · Accepted Answer

In order to balance the equation, we need 2 molecules of hydrogen gas. This can be seen by comparing the number of hydrogen atoms on each side of the equation (4 on the reactant side, 8 on the product side). Multiplying the coefficient for hydrogen gas by 2 will give us the correct number of hydrogen atoms on each side.
