- Nitroglycerin (C3H5N3O9) is a powerful explosive. Its decomposition may be represented by 4C3H5N3O9 ⟶ 6N2 + 12CO2 + 10H2O + O2 This reaction generates a large amount of heat and many gaseous products. It is the sudden formation of these gases, together with their rapid expansion, that produces the explosion.

- 5. An experiment is performed to measure the mass percent of CaCO3(s) in eggshells. Five different samples of CaCO3(s) of known mass react with an excess of 2.0M HCl(aq) in identical sealed, rigid reaction vessels. The pressure of the gas produced is measured with a pressure gauge attached to the reaction vessel. Since the reaction is exothermic, the reaction system is cooled to its original temperature before Cooling the HCl(aq) to a lower temperature than it was in the original experiment the pressure is recorded. The experimental data are used to create the calibration line below. Using eggshells that are more finely powdered than those used in the original experiment 0.10- 0.09 0.08- Using 2.0M CH3COOH(aq) instead of 2.0M HCl(aq) 0.07 * 0.06- Reducing the volume of the reaction vessel 0.05 0.04 CLEAR ALL 0.03- 0.02- 0.05 0.10 0.15 0.20 Mass of CaCO3(s) (grams) The experiment is repeated with an eggshell sample, and the experimental data are recorded in the table below.
