1.7g of 2,3-dimethyl-1,3-butadiene is refluxed with 1.7g of maleic anhydride in toluene, and 1g of product is recrystallized from hexanes. The product has the formula C10H12O3. Calculate the percent yield. Answer to within 0.1 percent units.
Draw graphs representing Boyle's law, Charles's law, and Gay-Lussac's law for a fixed amount of gas. Make sure that you label each axis and state the assumptions for each law-that is, the variable(s) that is (are) held constant for each law.
Benzoyl peroxide, the substance most widely used against acne, has a half-life of 9.8 103 days when refrigerated. How long will it take to lose 7% of it potency (93% remaining)
The tank can hold a pressure of 50.0 atm before bursting. During a fire the gas is heated to 500 C. What is the gas pressure, and will the tank contain the gas without bursting

Hydrogen sulfide decomposes according to the following reaction, for which Kc = 9.30 10-8 at 700°C. 2 H2S(g) 2 H2(g) + S2(g) If 0.33 mol H2S is placed in a 4.7 L container
The temperature inside a pressure cooker is 1150C. Calculate the vapor pressure of the water inside the pressure cooker.
At the point of equilibrium there were 82.63 g of Br2(l). Determine the total pressure in the 50.0 L container at equilibrium.
A large gas flask is found to weigh 143.567 g. it is then filled with gas to a pressure of 735 torr at 31 C and found to weigh 1067.9 g (the density of water is 31 C is 0.997 g/mL). Assuming that the ideal gas equation applies, calculate the molar..
