Phosphorus burns in oxygen to possibly form two types of solid oxides. 3.1 g of elemental phosphorus (P) burns in 3.2 g of oxygen until the reactants are exhausted, releasing X kJ of heat.

(1) Determine the composition of the reaction products (expressed as chemical formulas) through calculation, and their corresponding mass (g) is              .

(2) Given that the heat of combustion of elemental phosphorus is Y kJ/mol, the heat of reaction ΔH for the reaction of 1mol P with O<sub>2</sub> to form solid P<sub>2</sub>O<sub>3</sub> is              .

(3) Write the thermochemical equation for the reaction of 1mol P with O<sub>2</sub> to form solid P<sub>2</sub>O<sub>3</sub>:
