Water is considered a polar molecule because-

• the oxygen side is partially positive and the hydrogen side is partially negative

• it can be found in the North and South Poles

• the oxygen side is partially negative and the hydrogen side is partially positive

• it can freeze

If you want to dissolve a solute faster in a solvent, you can-

• leave the solute alone in the solvent after you put it in there

• raise the temperature of the solvent

• leave the solute in big chunks

• cool the temperature of the solvent

Which of the following would slow the rate of dissolving when you are dissolving a solid in water?

• Raise the temperature of the solution

• Stirring the solution

• Use a very large chunk of the solid

• Crush the solid before mixing

The solubility of a gas in a given volume of water depends primarily on the-

• the rate at which the gas is stirred in the water

• surface area of the gas
