Why is water considered a polar molecule? a. the molecule has no overall charge. b. the oxygen and hydrogen atoms share electrons equally. c. the atoms in the molecule have partial charges. d. the molecule can only attract positive charges. i personally deduct that it is c but i would love some other opinions! : )

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
