Combustion reactions involve reacting a substance with oxygen. When compounds containing carbon and hydrogen are combusted, carbon dioxide and water are the products. Using the enthalpies of combustion for C4H4 (–2341 kJ/ mol), C4H8 (–2755 kJ/ mol), and H2 (–286 kJ/ mol), calculate ΔH for the reaction C4H4(g) + 2H2(g) → C4H8(g)
