Answer first gets brainliest
1. h2o molecules temperatures drop below freezing.
a. bond
b. form crystals
c. create solids
d. all of the above
2. when the ice forms, the hydrogen atoms in a water molecule
a. bond with hydrogen atoms in other water molecules
b. bond together and release the oxygen atom into the air
c. bond with the oxygen atoms in other water molecules
d. combine to form a single, heavier hydrogen atom
3. why is ice less fence than liquid water?

1 is B

Explanation:

Ice is crystalline so when water drops below freezing it forms crystals, I don't know the rest.

1. D

2. C

3. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density. More organized in the solid forms verse the liquid form.

Explanation:

1. When temperatures drop below freezing crystals are formed, and crystals = ice. Ice = solid and there are more bonds in ice than there are in water.

2. When ice forms the hydrogen atoms in a water molecule bond with the oxygen atoms in other water molecules.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
