Question: A scientist measures the standard enthalpy change for the following reaction to be -887.3 k) : 2NH3(g) + 3 N20(9) 4N2(g) + 3 H20(9) Based

A scientist measures the standard enthalpy change for the following reaction to be -887.3 k) : 2NH3(g) + 3 N20(9) 4N2(g) + 3 H20(9) Based on this value and the standard enthalples of formation for the other substances, the standard enthalpy of formation of N20(9) Is kJ/mol. A scientist measures the standard enthalpy change for the following reaction to be -558.3 kJ: H2CO(g) + O2(9).CO2(g) + H2O(1) Based on this value and the standard enthalples of formation for the other substances, the standard enthalpy of formation of H2CO(g) is kJ/mol
