Aspirin can be prepared from salicylic acid ( C7H6O3 ), which has a molar mass of 138.12 g/mol, and acetic anhydride ( C4H6O3), which has a molar mass of 102.04 g/mol. The density of acetic anhydride is 1.082 g/mL. C,H6O3 + C4HO3 → C3H3O4 + C2H3O2 What is the theoretical yield, in grams, of aspirin (C,H3O4), which has a molar mass of 180.15 g/mol, possible when reacting 3.01 g of salicylic acid with 3.73 mL of acetic anhydride? Type answer:

Hydrogen is manufactured on an industrial scale by this sequence of reactions: CH, (g) + H,0 (g) CO (g)+3 H, (g) K1 CO (g) + H,0 (g)= CO, (g)+H, (g) K2 The net reaction is: CH4 (g) +2 H,0 (g) CO, (g)+4H, (g) K Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K, and K,. If you need to include any physical constants, be sure you use their standard symbols, which you'll find in the ALEKS Calculator. K

Hydrogen sulfide, H2S, is produced during decomposition of organic matter. When 0.4190 mol H2S burns to produce SO2 (9) and H20(g), -217.0 kJ of heat is released. What is this heat in kilocalories? Heat = kcal

Colorful fireworks often involve the decomposition of barium nitrate and potassium chlorate and the reaction ofthe metals magnesium, aluminum, and iron with oxygen.(a) Write the formulas of barium nitrate and potassium chlorate.(b) The decomposition of solid potassium chlorate leads to the formation of solid potassium chloride and diatomic oxygen gas. Write an equation for the reaction.(c) The decomposition of solid barium nitrate leads to the formation of solid barium oxide, diatomic nitrogen gas, and diatomic oxygen gas. Write an equation for the reaction.(d) Write separate equations for the reactions of the solid metals magnesium, aluminum, and iron with diatomic oxygen gas to yield the corresponding metal oxides. (Assume the iron oxide contains Fe3+ ions.)

Combustion of hydrocarbons such as pentane (C5H₁2) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. 2. Suppose 0.440 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 18.0 °C. Calculate the volume of carbon dioxide gas that is produced. Round your answer to 3 significant digits. ローロ X 00 0°

Combustion of hydrocarbons such as hexane (C6H₁4) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid hexane into gaseous carbon dioxide and gaseous water. 2. Suppose 0.320 kg of hexane are burned in air at a pressure of exactly 1 atm and a temperature of 15.0 °C. Calculate the volume of carbon dioxide gas that is produced. Be sure your answer has the correct number of significant digits. OL X x10 Ś 18 Ar
