Helppp please hurry :))

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?

Heat is the total potential energy of a substance that can be transferred. true false

Δu of , in kj/kg, as it isto k, (a)as a of , (b) at , (c) at .
