When a molecule has an opposite electrical charge on each end, it is known as what?

cohesion

polar molecule

hydrogen bond

solution

Which statement explains why water molecules stick together?

both sides are negative

one side has a positive charge and the other side has a negative charge

The tightness or film across the surface of water that enables paper clips to float is ____________.

adhesion

capillary action

surface tension

polarity

Small insects can walk across the surface of calm water. Their feet push the surface of the water down slightly, somewhat like a person walking across a trampoline, but they do not break the surface. What is the best explanation for why this happens?

The insects are light enough so that they do not break the hydrogen bonds holding the water molecules together

The insects actually use their wings to hover slightly above the water's surface and they only skim it with their feet

The insects' feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water's surface

The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next

Which end of the water molecule has a slightly positive charge?

the oxygen end

the hydrogen end

both ends are slightly positive

neither end is positive
