Determine the value of the equilibrium constant, KC, for the reaction; A+2B<_>C+D, if the equilibrium concentration are: A=0.0253M, C=0.109M and D=0.011M

Smog is the term used to describe the combination of fog and smoke

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
