Propane cap c sub 3 cap h sub 8 g , Δ⁢H_f=−103.8kJ/mol reacts with oxygen to produce carbon dioxide CO sub 2 , Δ⁢H_f=−393.5kJ/mol and water cap h sub 2 cap o , Δ⁢H_f=−241.82kJ/mol according to the equation. cap c sub 3 cap h sub 8 g plus 5 cap o sub 2 g rightarrow 3 CO sub 2 g plus 4 cap h sub 2 cap o g What is the enthalpy of combustion (per mole) of cap c sub 3 cap h sub 8 g ? Use Δ⁢H_rxn=∑(Δ⁢H_f_1p⁢r⁢o⁢d⁢u⁢c⁢t⁢s)−∑(Δ⁢H_f_1r⁢e⁢a⁢c⁢tan⁡t⁢s)
