When hydrogen reacts with iodine, we can show the reaction as follows
h-h + 1-1>
2(h-1)
(a)
given the following bond energies, calculate the heat of reaction
(h - h: 436, 1-1: 151kj, h-1: 298kj)

How is electrolysis most commonly used to produce an energy source? a - splitting water molecules produces oxygen, which organisms breathe to fuel their bodies. b - splitting water molecules produces hydrogen gas, which is used to power machines through hydrogen fuel cells. c - splitting carbon dioxide molecules produces coal, a form of carbon that can be burned to produce heat. d - splitting carbon dioxide molecules produces natural gas, which can be burned to generate electricity in power plants.
