Determine the enthalpy of the reaction using Hess's law

Ag₂O (s) + 2 HCl (aq) → 2 AgCl (s) + H₂ (g) + O₂ (g)

Given the following data

2 Ag (s) + 1/2 O₂ (g) → Ag₂O (s) ΔH = -31.1 kJ/mol

Ag (s) + 1/2 Cl₂ (g) → AgCl (s) ΔH = -127.0 kJ/mol

H₂O (l) + Cl2 (g) → 2 HCl (aq) + 1/2 O₂ (g) ΔH = -48.6 kJ/mol

H₂ (g) + O₂ (g) → H₂O (l) ΔH = - 285.8 kJ/mol
