NH4NO3 is frequently used as a fertilizer and in explosive compounds dlta Hf values of this compound nd H20 are -365kJmol-1 and -286kJmol-1 respectively. Calculate the amount of heat released bye the dissociation of 1mol of NH4NO3 according to the following reaction
2NH4NO3-->2N2 4H2O O2
dHrxn = (n*dH products) - (n*dH reactants)
Note: dH N2 and O2 are zero.
