2H2 + O2 → 2H2O. Step 2: Compute for the number of moles of H2O formed. Using 4 mol of H2. n H2O = 4 mol H2 × (2 mol H2O / 2 mol H2) n H2O = 4 mol H2O. Using 3 mol of O2. n H2O = 3 mol O2 × (2 mol H2O / 1 mol O2) n H2O = 6 mol O2. Step 3: Determine the limiting and excess reactant. H2 is the limiting reactant. (produces less amount of H2O ...
