Question 1

What would be the standard enthalpy change for the reaction of 1.00 mole of H2(g) with 1.00 mole of  Cl2(g) to produce 2.00 moles of HCl(g) at standard state conditions?
         [ΔH°f (HCl(g))= –92.3 kJ/mol]


Question 2

When an automobile engine starts, the metal parts immediately begin to absorb heat released during the combustion of gasoline.  How much heat will be absorbed by a 165 kg iron engine block as the temperature rises from 15.7°C to 95.7°C? (The specific heat of iron is 0.489 J/g·°C.)
