Ammonia gas is formed from hydrogen gas and nitrogen gas according to the following chemical reaction: 3 H2(g) + N2(g) --> 2 NH3(g)   ΔH = - 92.4 kJ/rxn   Calculate the total energy released (in kJ) if one mole of ammonia gas is formed. Calculate the total energy released (in kJ) if six moles of hydrogen gas and two moles of nitrogen gas are combined and the above reaction occurs. Calculate the total energy released (in kJ) if you combine 6.00 g of hydrogen gas and 24.00 g of nitrogen gas and the above reaction occurs.
