Answer 1

4. The fact that ice is less dense than water is related to the fact that ____. (1 point)
the molecular structure of ice is much less orderly than that of water
the molecules of ice are held to each other by covalent bonding
ice has a molecular structure in which water molecules are arranged randomly
ice has a molecular structure that is an open framework held together by hydrogen bonds ***

Answer 2

@sparki1 please help

Answer 3

@KinzaN help ?

Answer 4

The surface tension of water is considerable--you can't say it's greater than all other liquids but it would definitely be higher than most other liquids. The reason being the formation of hydrogen bonds between water molecules.

And a water molecule is bent. I can show you why if you'd like.

I answered the third question in my first explanation. =)

Answer 5

Question four is either b or d, I can't decide.

Answer 6

I know that ice is less dense because the volume of ice is greater than that of water for equal number of molecules--there is more H-bonding in water than in ice. Not sure which answer that best corresponds to. Sooorry.

Answer 7

I have fell in love lol (: thank you @KinzaN

Answer 8

Haha, you're welcome.
