"Webb29 maj 2024 · 2Mg (s) + 2HCl (aq) → H 2(g) + 2MgCl (s) Since the stoichiometric coefficients are equal for both reactants, the Mg is the limiting reagent because the amount (0.100 mol) is lesser than the amount of HCl (0.500 mol). So the amount of H 2 produced is given by: 0.100 mol Mg x (1 mol H 2) / (2 mol Mg) = 0.050 mol H 2 " - Mg s +2hcl aq → mgcl2 aq +h2 g net ionic
