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 ( C3H5NO33 ) into gaseous dinitrogen, gaseous dioxygen, gaseous water and gaseous carbon dioxide. 2. Suppose 37.0L of carbon dioxide gas are produced by this reaction, at a temperature of −9.0°C and pressure of exactly 1atm . Calculate the mass of nitroglycerin that must have reacted. Round your answer to 3 significant digits. g

Answer 1

Balanced chemical equation is- 4C3H5(NO3)3(1)→ 6 Nz4g) + O219) + 1012018) +1260219 To calculate Applying equation the moles of co2 produced ideal gas PV = nRT = 1athx 37.0k RT 0.0821 atmyx 2 64 k. mol-x 1.71 mol. from the reaction nolee of C3 4 5 (403) 3 used - moles of coo 4 nC 3 H 5 (2003) 0.57 nuola = mass moles molar 0.57 molx Mass. 227 gineel mass 12992
