Question

Nitroglycerin is a dangerous powerful explosive that violently decomposes when it is shaken or dropped. The Swedish chemist Alfred Nobel (1833-1896) founded the Nobel Prizes with a fortune he made by inventing dynamite, a mixture of nitroglycerin and inert ingredients that was safe to handle. 1. Write a balanced chemical equation, including physical state symbols, for the decomposition of liquid nitroglycerin (C3Hs(N03),) into gaseous dinitrogen, gaseous dioxygen, gaseous water and gaseous carbon dioxide. 1 2. Suppose 24.0 L of carbon dioxide gas are produced by this reaction, at a temperature of -5.0 °C and pressure of exactly 1 atm. Calculate the mass of nitroglycerin that must have reacted. Be sure your answer has the correct number of significant digits

Explanation / Answer

1)

balanced equation :

4C3H5(NO3)3 (l)   -----------------> 12CO2 (g) + 6N2 (g) + 10H2O (g) + O2 (g)

2)

pressure = 1 atm

temperature = - 5 oC = 268.15 K

volume = 24.0 L

P V = n R T

1 x 24 = n x 0.0821 x 268.15

n = 1.09

moles of CO2 = 1.09 mol

4 mol nitroglycerin ------------- > 12 mol CO2

   ??                          -------------> 1.09 mol CO2

moles of nitoglycerin = 1.09 x 4 / 12 = 0.363

mass of nitoglycerin = 82.5 g
