Nitric oxide (NO) can be formed from nitrogen, hydrogen and oxygen in two steps. In the first step, nitrogen and hydrogen react to form ammonia: N2(g) + 3 H,(g) - 2 NH,(g) AH=-92. kJ In the second step, ammonia and oxygen react to form nitric oxide and water: 4 NH,(g) + 50,(g) -4NO(g) + 6H,0(g) AH=-905. kJ Calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. Round your answer to the nearest kJ.

THERMODYNAMICS: A 1.09 g sample of acetic acid (HC2H302) was burned in excess oxygen in a bomb calorimeter. The calorimeter, which alone had a heat capacity of 2.67 KJPC, contained 7 g of water. The temperature of the calorimeter and its contents increased from 24.3°C to 27.95°C. What is AH (in kJ) for the combustion per 1.00 mol of acetic acid? MW of acetic acid is 60 g/mol. (Round off the final answer to ONE decimal place. Do not include the unit.)
