Use the standard enthalpies of formation for the reactants and products to solve for the δhrxn for the following reaction. (the δhf of ca(oh)2 is -986.09 kj/mol and liquid h2o is -285.8 kj/mol.) ca(s) + 2h2o(l) > ca(oh)2 (s) + h2(g)

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.
