Asked by Brian

(1) 2 Ni(s) + O2 (g) --> 2NiO(s) delta H= -479.4 kJ
(2) Ni(s) + Cl2(g) --> NiCl2(s) delta H= -305.3 kJ

Using equations 1 and 2 and Hess's Law, determine the amount of moles Nickel (ii) Chloride that was combusted given the following:

volume = 15.45 L
pressure = 2.29 atm
*each time it is performed, the combustion on a specific mass of NiCl2 required 58.2 kJ of energy
