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 (C₂H5(NO3)₂) dioxygen, gaseous water and gaseous carbon dioxide. into gaseous dinitrogen, gaseous 2. Suppose 13.0 L of carbon dioxide gas are produced by this reaction, at a temperature of -11.0 °C and pressure of exactly 1 atm. Calculate the mass of nitroglycerin that must have reacted. Round your answer to 3 significant digits. ローロ X 00 0° 2 画 olo

If 1000 L of gasoline has spilled into the street (MW=117 g/mol, density=0.7 g/mL which is true for octane) then firefighters add a lot of a material that dissolves into it that reduces the vapor pressure (liquid octane doesn’t burn, only the vapors). The firefighters put 500 kg of a material into the gasoline and reduced its vapor pressure from the pure partial pressure of 10.0 kPa down to 8.0 kPa. What is the molecular weight of the material that was added? (hint: use Raoult’s Law, which relates changes in pressure to the mol fractions.

a sample of dolomitic limestone containing only CaCO3 and MgCO3 was analyzed a) when a 0.2800-gram sample of this limestone was decomposed by heating, 75.o milliliters of CO2 at 750. mm Hg and 20°C were evolved. How many grams of CO2 were produced? b) write equations for the decomposition of both carbonates described above.  c) It was also determined that the initial sample contained 0.0448-gram of calcium. What percent of the limestone by mass was CaCO3? d) How many grams of the magnesium-containing product were present in the sample in a. after it had been heated?

Gypsum is a relatively soft rock made of CaSO4. Rainwater percolates through gypsum, dissolves some of the rock, and eventually becomes saturated with Ca2+ ions and SO²- ions. A geochemist takes a sample of groundwater from a cave and finds that it contains 8.4 x 10-3 M SO42- and 5.8 x 10-3 M Ca²+. (The ratio is not 1:1 because other sulfate rock contributes some of the SO42- ions to the solution.) Use these data to determine the solubility product of CaSO4.
