Answered by DrBob222
You need to learn how to write a question. The equation is exothermic because it is giving off 285.8 kJ of heat.

If the energy number is on the product side of the equation, it is exothermic as the one you've posted. If the energy number is on the reactant side of the equation, it is endothermic. => H₂O(l) + 44Kj => H₂O(g)
