An equilibrium mixture of SO2, SO3 and O2 gases is maintained in a 11.5 L flask at a temperature at which Kc = 55.2 for the reaction shown below. If the number of moles of SO3 in the flask at equilibrium is twice the number of moles of SO2, how much O2 is present in the flask at equilibrium? Show all work.
2 SO2 (g) + O2 (g) ? 2 SO3 (g)
The value of E° for each of the cells is 2.04 V. Suppose that in starting a car on a cold morning a current of 108 A is drawn for 14 seconds from the car battery. How many grams of Pb would be consumed? (M r(Pb)=207.19 g/mol)

A compound contains only carbon, hydrogen, nitrogen, and oxygen. Combustion of a 2.18 g sample burns in excess oxygen yields 3.94 g of CO2 and 1.89 g of H2O. A separate experiment shows that a 1.23 g sample contains 0.235 g of N.
Calculate the molar solubility of Cu(OH)2, Ksp = 2.2 × 10-20, in 0.82 M NH3. Don't forget to use the complexation reaction Cu2+ + 4 NH3 ? Cu(NH3)42+, K = 5.0 × 1013.
