Consider the reaction of `NH_(3)(g)` with `CuO`:
`3CuO(s)+2NH_(3)(g)rarr3Cu(s)+N_(2)(g)+3H_(2)O(l)`
The standard enthalpy of formation of `NH_(3)(g)`, `CuO(s)` and `H_(2)O(l)` are `-46`, `-155` and `-285(kJ)/(mol)` respectively. The amount of heat released when `25.9g` of `CuO(s)` reacts with `2.72g` of `NH_(3)(g)` is
(Atomic mass: `Cu=63.5gmol^(-1)`)
