Using the values of standard enthalpy of formation NH3 = -46.19 KJ/mol

N2H4 = 95.40 KJ/mol

H2O = -285.83 KJ/mol

determine the standard enthalpy of formation for the reaction

4NH3 + O2 --> 2 N2H4 + 2 H2O

the sum of reactants is KJ/mol

the sum of products is KJ/mol

The heat of formation is KJ/mol

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
