On Easter Sunday, April 3, 1983, nitric acid spilled from a tank car near downtown Denver, Colorado. The spill was neutralized with sodium carbonate: 2 HNO 3 ( a q ) + Na 2 CO 3 ( a q ) → 2 NaNO 3 ( a q ) + H 2 O ( l ) + CO 2 ( g ) a. Calculate ∆ H° for this reaction. Approximately 2.0 ×10 4 gal nitric acid was spilled. Assume that the acid was an aqueous solution containing 70.0% HNO 3 by mass with a density of 1.42 glcm3. What mass of sodium carbonate was required for complete neutralization of the spill, and what quantity of heat was evolved? ( Δ H f ° for NaNO 3 (aq) = −467 kJ/mol) b. According to The Denver Post for April 4, 1983, authorities feared that dangerous air pollution might occur during the neutralization. Considering the magnitude of ∆ H°, what was their major concern?
