If the total heat energy for the reaction of magnesium metal (0.500 g) with HCl is given by (Δqtotal = 1000.0 J). Calculate the enthalpy change (ΔHrxn) for this reaction. Enthalpy change for this reaction is given by the relationship: ΔHrxn = -Δqtotal/moles of Mg. The molar mass of magnesium is 24.305 g/mol
