Best ResponseYou've already chosen the best response.22H2 + 2O2 > 2H2O Ask yourself What does standard formation mean? It's the amount of energy you need to generate, 1 mol of a certain compound if I remember correctly. Now look at the periodic table, all those elements have 0 heat of formation because they occur naturally, and if something occurs naturally it has no heat of formation. Hydrogen gas Oxygen gas Those two are gasses that are naturally occurring so they are 0.

Best ResponseYou've already chosen the best response.2However you must take into account that this must be one mole of a compound formed from its constituents.

Best ResponseYou've already chosen the best response.2Should be H2 + 1/2O2 > H2O

Best ResponseYou've already chosen the best response.2The equation is set up properly but it should always result in one mole produced not two.

Best ResponseYou've already chosen the best response.2No problem, yeah it should usually be for just one mole but this is correct.
