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 SO2- 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.

In determining the volume of CO2 in the flask, the flask was filled with water and the total volume of the water in the stoppered flask was measured. A student filling the Erlenmeyer flask with water was in a rush and did not notice small air bubbles under the stopper. How would this error affect the experimental molar volume of CO2?

The Hydratres of Chromium(III) chloride have 3 known forms: A is a hexahydrate, B is a pentahydrate, C is a tetrahydrate. Adding excess of silver ion to a solution of 1 mole of each results in the following precipitates of silver chloride. A 3 moles, B 2 moles, C 1 mole. Using this information deduce the actual structure of each hydrate and write the corresponding name.
