Solution:

An aqueous solution is saturated in both potassium chlorate and carbon dioxide gas at room temperature. What happens when the solution is warmed to 85˚C? a) Potassium chlorate precipitates out of solution. b) Carbon dioxide bubbles out of solution. c) Potassium chlorate precipitates out of solution and carbon dioxide bubbles out of solution. d) Nothing happens; all of the potassium chloride and the carbon dioxide remain dissolved in solution.
