On Easter Sunday, April 3, 1983, nitric acid spilled from a tankcar near downtown Denver, Colorado. The spill was neutralizedwith sodium carbonate:a. Calculate _H_ for this reaction. Approximately 2.0 _ 104 galnitric acid was spilled. Assume that the acid was an aqueoussolution containing 70.0% HNO3 by mass with a density of1.42 g/cm3. How much sodium carbonate was required forcomplete neutralization of the spill, and how much heat wasevolved? (_Hf_ for NaNO3(aq)_ _467 kJ/mol)b. According to The Denver Post for April 4, 1983, authoritiesfeared that dangerous air pollution might occur during theneutralization. Considering the magnitude of _H_, what wastheir major concern?
