The image represents the reaction between a certain number of molecules of N2 and H2. Two squares are shown. Inside the left square one unit of two joint circles if shown. The molecular formula of nitrogen gas is shown on top of this square. The square on the right has four units of two joint circles. The molecular formula for hydrogen gas is shown on top of this square If the maximum amount of NH3 is formed during the reaction, what is the leftover reactant? One molecule of N2
One molecule of H2
Two molecules of N2
Two molecules of H2
