Question 1

Consider the following reaction:

              2Al(s) + 3Cl2(g) → 2AlCl3(s);    ΔH = -1390.81 kJ

a) Is the reaction exothermic or endothermic?

b) How much heat is produced/required when 10.0 g AlCl3 forms.

c) How many grams of Al are required to absorb/evolve 1.00 kJ of energy?



Question 2

Consider the following standard heats of formation:

              P4O10(s) = -3110 kJ/mol

              H2O(l) = -286 kJ/mol

              H3PO4(s) = -1279 kJ/mol

Calculate the change in enthalpy for the following process:

              P4O10(s) + 6H2O(l) → 4H3PO4(s)
