A.A water molecule has two dipole moments and they cancel each other.
B.A water molecule is symmetrical and therefore is nonpolar.
C.The electronegativities of hydrogen and oxygen are equal and therefore a water molecule is nonpolar.

D @iPwnBunnies

Answer 1

D is what I think lol

Answer 2

Which compound listed below will dissolve in water?

Answer 3

Sorry I posted 2

Answer 4

For the first one it is D. Had to think about it, I don't see water as asymmetric, but I think it is.

Answer 5

Sweet.

Answer 6

For the second question...Looks like all of them can dissollves in water. Usually certain ionic compounds don't dissolve in water. Not sure about these covalent substances.

Answer 7

Hmm ok

Answer 8

Which of the following statements about Lewis structures is FALSE?
A.A duet is a stable electron configuration for helium.
B.A covalent bond occurs when electrons are shared.
C.An octet is when an atom has 8 valence electrons.
D.An ionic bond occurs when electrons are transferred.
E.All of the above statements are true.

E for this?

Answer 9

E looks good. Don't know why they put that ionic bond thing in there lol. I don't use Lewis structures for ionic compounds.
