Answer 3

Water

Question 4

What are simple molecules

Answer 4

Bonds of covalent molecules held together by intermolecular forces

Question 5

Why are most simple molecules gases at room temp

Answer 5

The weak intermolecular forces do not require a lot of energy to break

Question 6

Why do small covalent molecules not conduct electricity

Answer 6

Because the molecules do not have an overall electric charge
