Which side of a water molecule sticks to a CO32- ion?
a. The oxygen (O-) atom
b. The hydrogen (H+) atom(s)
QUESTION 6
-
What is the term for water turning from liquid to gas?
a. latent heat of freezing
b. latent heat of melting
c. latent heat of vaporization
d. latent heat of condensation
Homework Answers
5) The hydrogen side of water molecule sticks with the CO3 2- ion. Because the net anionic charge of 2- will form bond with cationic hydrogen.
6) Water turning from liquid to gas is called vaporization and the heat required to vaporize is called latent heat of vaporization.

a)
The water molecule consists of two hydrogen atoms and one oxygen
atom. Since the oxygen atom has a higher electronegativity than the
hydrogen atom, the side of the molecule with the oxygen atom has a
partial negative charge.
Assume that the partial positive charge on each hydrogen atom is
Q2 = 0.512 x 10-19 C. What is the
electric charge Q1 on the Oxygen atom?
b)
The water molecule forms an angle, with hydrogen atoms at the
tips and...
