Considering the limiting reactant, how much heat is produced at constant pressure if 0.243 g of magnesium reacts with 100.0 mL of 0.300 M HCl according to the reaction below? Mg(s) + 2HCl(aq) => MgCl2(aq) + H2(g); ΔHo = –462.5 kJ

Calculate the ΔH  for the following reaction using the given bond energies. Show work for credit (H – F = 565 kJ; O – O = 494 kJ; H – O = 463, O – F = 184). F2O(g) + H2O(g) => O2(g) + 2 HF(g)

The following combination of signs for heat and work (respectively, heat first, work, next in the answer) represents a system that is gaining heat from the surroundings, and surroundings are doing work on the system?
