Asked by Jay
Determine how much heat (in kilojoules) is evolved or absorbed in the reaction of 1.05 g of Na with H2O:
2Na(s)+2H2O(l) →2NaOH(aq)+H2(g),ΔH∘=−368.4 kJ
2Na(s)+2H2O(l) →2NaOH(aq)+H2(g),ΔH∘=−368.4 kJ

heat=.368kJ/2moles * 1.05/23
Heat of reaction is not given per mole, it is given per 2 moles Na, or 2 moles water.
