Corn farmers typically use 5000 kg of ammonium nitrate per square kilometer of cornfield per year. Ammonium nitrate can be prepared by the following reaction. How much nitric acid would be needed to make the fertilizer for 1km2 of cornfield per year? NH3 + HNO3 ---> NH4NO3

a) __________ kg of HNO3 The ammonium ions can be converted into NO3 by bacterial action. If 10% of the ammonium component of 5000kg of fertilizer ends up as nitrate, how much oxygen would be consumed? NH4 + 2O2 ----> NO3 +H2O+2H

b) __________ kg of O2
