WebbΔHrxn = qrxn / (moles magnesium) The balanced chemical equation for this reaction is: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g) The enthalpy of reaction for your experiment would be based on the heat lost or gained per 1 mole of magnesium, because magnesium is the limiting reagent. 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
