Write the thermochemical equations for the following reactions according to the given conditions

(1) 14g of C2H4(g) reacts with an appropriate amount of O2(g) to produce CO2(g) and H2O(l), releasing 705.5 kJ of energy.

(2) 1 mol of H2(g) reacts with gaseous iodine to produce HI gas, releasing 14.9 kJ of heat.

(3) When a grams of acetylene gas (C2H2) is completely burned, 1 mol of carbon dioxide gas and liquid water are produced, and b kJ of heat is released. The thermochemical equation for the combustion of acetylene is\_ \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_
