Does the reaction need to be balance first before proceeding with the solution?

Extracted text: Show complete solution. Round everything to four decimal places and box all final answers. The molar heat of formation of NH4N03 (s) is -367.54 KJ and those of N20 (g) and H20 (1) are 81.46 and -285.8 KJ respectively at 25°C and 1 atmospheric pressure. Calculate delta H and delta U of reaction. NH4NO3(s) → N20(g) + H20(I)
