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 C,H4 (-2341 kJ/mol), C,Hs (- 2755 kJ/mol), and H2 (- 286 kJ/mol), calculate AH for the reaction. C,H, (9) + 2 H2 (g) C, Hs (g) ΔΗ kJ

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), C,Hs (-2755 kJ/mol), and
H2 (- 286 kJ/mol), calculate AH for the reaction.
C,H4 (9) + 2 H2 (9) → C4H$ (g)
