Mаgnesium metаl reаcts with hydrоchlоric acid accоrding to the equation: Mg(s) + 2HCl(aq) --> MgCl2(aq) + H2(g) In an experiment 0.158 g of Mg metal is combined with enough HCl to make 100.0 g of solution with a specific heat capacity of 4.184 J∙g–1∙C°–1 in a calorimeter. The temperature of the solution rises from 25.6 oC to 32.8 oC. What is the change in enthalpy, DH, of the reaction per mole of Mg used? The molar mass of magnesium is 24.31 g∙mol–1.
