Using the stаndаrd enthаlpies оf fоrmatiоn Hf0 given and your knowledge of Hf0 values for elements in their standard states, determine the enthalpy of this reaction. Assume that O2 (g) does represent oxygen. 2A3X2 (g) + O2 (g) → 2A3X (g) + 2XO (g) Hf0 values A3X2 (g) = –{C2} kJ/mol A3X (g) = –{CO} kJ/mol XO (g) = {NO} kJ/mol For full credit: Round your answer to the ones place so that there are no decimals. (EX: 12.3 = 12) Include the correct unit.
