Calculate the enthalpy change when 6.80g of NH_(3) is passed over heated CuO. The standard heat enthalpies of NH_(3(g)),CuO_((s)) and H_(2)O_((l)) are -46.0,-155.0 and -285.0kJ mol^(-1) respectively and the change is NH_(3)+(3)/(2)CuO rarr (1)/(2) N_(2(g))+(3)/(2) H_(2)O_((l))+(3)/(2)Cu_((s)) .

Calculate the enthalpy change when 6.80g of NH_(3) is passed over heat

1.	Calculate the enthalpy change when 6.80g of NH_(3) is passed over heated CuO. The standard heat enthalpies of NH_(3(g)),CuO_((s)) and H_(2)O_((l)) are -46.0,-155.0 and -285.0kJ mol^(-1) respectively and the change is NH_(3)+(3)/(2)CuO rarr (1)/(2) N_(2(g))+(3)/(2) H_(2)O_((l))+(3)/(2)Cu_((s)) .
