Rationalize the temperature dependence of the solubility of a gas in water in terms of the kinetic molecular theory.
In some regions of the southwest United States, the water is very hard. For example, in Las Cruces, New Mexico, the tap water contains about 560 g of dissolved solids per milliliter. Reverse osmosis units are marketed in this area to soften water. A typical unit exerts a pressure of 8.0 atm and can produce 45 L water per day. a. Assuming all of the dissolved solids are MgCO3 and assuming a temperature of 27C, what total volume of water must be processed to produce 45 L pure water? b. Would the same system work for purifying seawater? (Assume seawater is 0.60 M NaCl.)
Acetylene can be made by reacting calcium carbide with water. CaC2(s) + 2 H2O() C2H2(g) + Ca(OH)2(aq) Assume that you place 2.65 g CaC2 in excess water and collect the acetylene over water. The volume of the acetylene and water vapor is 795 mL at 25.0 C and a barometric pressure of 735.2 mmHg. Calculate the percent yield of acetylene. The vapor pressure of water at 25 C is 23.8 mmHg.
