Calculate the Enthalpy of the following problem:

CS2 (l) + 3O2 (g) → CO2 (g) + 2 SO2 (g)

Given:

C (s) + O2 (g) → CO2 (g); ΔHf = -393.5 kJ/mol

S (s) + O2 (g) → SO2 (g); ΔHf = -296.8 kJ/mol

C (s) + 2 S (s) → CS2 (l); ΔHf = 87.9 kJ/mol

Given the following equations:

H2S(g) + 3/2 O2(g) → H2O(l) + SO2(g) ΔH = -563 kJ

CS2(l) + 3O2(g) → CO2(g) + 2SO2(g) ΔH = -1075 kJ

Use Hess's Law to calculate ΔH for the reaction below: CS2(l) + 2H2O(l) → 2H2S(g) + CO2(g) ΔH = ____ kJ

Solve in details.
