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 (C,H;(NO;),) into gaseous dinitrogen, gaseous dioxygen, gaseous water and gaseous carbon dioxide. 믐 x10 4C;H, (NO,), (1) → N, (3) + 0, (3) + CO,(8) + H,0(g) ? 2. Suppose 74.0L of carbon dioxide gas are produced by this reaction, at a temperature of - 13.0 °C and pressure of exactly 1 atm. Calculate the mass of nitroglycerin that must have reacted. Round your answer to 3 significant digits.

Solve correctly please. (Gpt/Ai wrong answer not allowed)
