Calculate the energy required to heat 197.0g of graphite from 3.1C to 14.2C. Assume the specific heat capacity of graphite under these conditions is 0.710Jg1K1. Round your answer to 3 significant digits. N2(g)+3H2(g)2NH3(g)H=92.kJ In the second step, ammonia and oxygen react to form nitric acid and water: NH3(g)+2O2(g)HNO3(g)+H2O(g)H=330.kJ Calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these reactions. Round your answer to the nearest kJ
