1. how do molecules of a polar compound differ from those of a nonpolar compound?

2. What happnens when ionic compounds are mixed with water?

3. what is capillarity?

4. Critical Thinking: Most automobiles have water-cooled engines. What must be true about a solution that can replace water in the cooling system, such as antifreeze?

i really don't get these! pleaseee help:) thank you!

1.Polar molecules have one end that is more negative(it has the electrons more of the time) and one end that is positive(it has the electrons less of the time) In other words the electrons that are shared in the covalent bond are not shared evenly. Therefore, it can attract other things that are polar. Non polar molecules share evenly and do not have a partial charge so do not attract things that have charges.
