    4N2H4 (2) + 2N204 (1) - -> 6N2 (g) + 8H20 (g), AHO-2098 kJ

    Explanation:

    2N2H4 (2) + N204 (1) - -> 3N2 (g) + 4H20 (g), AHO-1049 kJ

    when 6 mol of nitrogen are formed?

    The ratio of Nitrogen in the previous therrmochemical equation to when 6 mol f nitrogen are formed is 2; 6/3 = 2.

    So to get the new thermoochemical equation, multiply all parameters in the given equation by 2.

    We have;

    4N2H4 (2) + 2N204 (1) - -> 6N2 (g) + 8H20 (g), AHO-2098 kJ
