1) Example 6.7 - What is DHrxn/mol Mg for the reaction Mg(s) + 2 HCl(aq) → MgCl2(aq) + H2(g) if 0.158 g Mg reacts in 100.0 mL of solution to change the temperature from 25.6°C to 32.8°C? Cs of the solution is the same as the water = 4.184 J/g.C, Use the density of water for the density of the solution that is 1 g/ml.

2) How much heat is evolved in the complete combustion of 13.2 kg of C3H8(g)?

C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(g) DH = -2044 kJ
