Using the data in the check your learning section of example 5.5, calculate δh in kj/mol of agno3(aq) for the reaction: nacl(aq) + agno3 (aq) ⟶ agcl(s) + nano3 (aq)

In an exothermic reaction the bonding energy of the product is: less than the reactants same as the reactants greater than the reactants dependent upon the presence of a catalyst
