A 140-ml sample of gas is collected over water at 22°C and 753 torr. What is the volume of the dry gas at STP? (The vapor pressure of water at 22°C - 20. torr)
128 ml

108 ml
120 mL
none of these

Why do cells appear different in distilled water than they do in 10% salt water?

If an area has high air pressure and low humidity, what type of weather will it most likely have? plz !

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.
