Calculate the enthalpy change for the hydration of MgSO4 using the following data:MgSO4(s) → MgSO4(aq) ΔH1 = 44.5 kJ/molMgSO4(aq) + 7H2O(l) → MgSO4 • 7H2O(s) ΔH2 = -63.2 kJ/mol.

A chemistry student needs to determine the enthalpy change for the reaction of nitrogen gas reacting with hydrogen gas to form ammonia gas, given that they have the following information:N2(g) + 3H2(g) --> 2NH3(g) ΔH1 = -92.4 kJ/mol2H2(g) + O2(g) --> 2H2O(l) ΔH2 = -572.0 kJ/molN2(g) + O2(g) --> 2NO(g) ΔH3 = +180.6 kJ/molUse Hess's law to calculate the enthalpy change for the reaction:2NH3(g) + 5O2(g) --> 2HNO3(aq) + 2H2O(l)
