On Easter Sunday, April 23, 1983, nitric acid (HNO3) spilled from a tank car near downtown Denver, Colorado. The spill was neutralized with sodium carbonate (Na2CO3).
2HNO3(aq) + Na2CO3(s) -> 2NaNO3(aq) + H2O(l) + CO2(g) deltaH=-69.0kJ

a. How much heat is released by the neutralization of 2.94x10^3kg of nitric acid?

b. If 1,000kJ were produced, what volume of CO2 would be produced at 1 atm and 30C?
