WebThe heat change of the chemical reaction is related to the heat changes of the surrounding solution and calorimeter by the law of conservation of energy: q reaction + q solution + q calorimeter = 0 1. Write the balanced equation for the reaction between magnesium metal and hydrochloric acid. Include physical states. Mg(s) + 2HCl(aq) -> MgCl 2 ... WebEnthalpy is the total heat content of a system. The enthalpy of reaction (ΔHrxn) is the change in enthalpy due to a chemical reaction. The general formula is: Δ H r x n = H f. i. n a l − H i n i t a l = q where q is heat. If ΔH rxn> 0, the reaction is endothermic (the system pulls in heat from its surroundings)
