In the following reaction, how many moles of CH3OH are required to
produce -1.501 x 103 kJ of heat?
2 CH3OH (1) + 3 O2 (g) – 2 CO2 (g) + 4 H2O(g) AH° = -1280. kJ

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

it is stable as it is in group 0 which have full outer shells of electrons
