When a solution containing 1.4g of Ba(NO3)2 and 2.4 g of NH2SO3H is boiled, a precipitate forms. This precipitate may be Ba(NH2SO3)2, BaSO4, or BA(NH2)2. You can find these products in the reactions whose equations you balanced in the first reaction.

Ba(NO3)2+NH2SO3H+H2O----BaSO4+HNO3+NH4NH3
Ba(NO3)2+NH2SO3H+H2O-----BaSO4+NH4NO3+HNO3
Ba(NO3)2+2NH2SO3H+2H2O------Ba(NH2)2+2H2SO4+2HNO3
