Suppose you place 0.0300 g of magnesium chips in a coffee-cup calorimeter and then add 100 0 ml. of 1.00 M HCl. The reaction that occurs is
Mg(s) + 2 HCl(aq) → H2(g) + MgCl2(aq)
The temperature of the solution increases from 22.56 °C (295.71 K) to 23.91 °C (297.06 K). What is the enthalpy change (kJ/mol) for the reaction per mole of Mg? Assume a specific heat capacity of the solution is 4.20 J/g • K and the density of the HCI solution is 1.00 g/mL.
