Answer to Question #76595 in General Chemistry for Ben

Question

Balance the following reactions of combustion

a) C2H4 (g) + O2 yields CO2(g) +H20(g) + Energy

The energy is throwing me off from doing a normal balancing equation. Can you help me with this

Answer 1

C2H4(g) + 3 O2 → 2 CO2(g) + 2 H20(g) + Energy
“Energy” means that the reaction is exothermic and the heat (energy) is released. There is no need to balance it.
