Not much.
Ice is only water, when the molecules are submitted to low temeperatures and have formed a crystalline arrangement of low density. In ice, the molecules arange themselves in hexagons with hydrogen bonds binfing each molecule.
When ice melts it turnes into water and the molecules leave the crystalline shape and come back to their normal density. In water, not all molecules are binded forming short and irregular lines.
→ In the image below, you can see the arrangement of ice and water.

Answer:
- <u><em>B. Structural</em></u>
Explanation:
The <em>atomic </em>or molecular <em>formula </em>represents each kind of atom by its chemical symbol and the number of each kind of atom by a subscript, but it does not show how they are connected. Thus, many different compounds have the same atomic or molecular formula.
The <em>skeletal formula</em> is a kind of abbreviated molecular formula in which the carbon and hydrogen atoms are not indicated but are understood. The skeletal formula shows the chain, the double and triple bonds, and the atoms different to carbon and hydrogen. Each vertex on the chain represents on carbon atom, and the hydrogen atoms (not shown) are the needed to complete the four valence electrons of each carbon atom.
The<em> structural formula </em>shows each atom, using the chemical symbol, and how they are connected in the compound, i.e. the bonds, using short lines.
For instance, the structural formula for the simplest organic compound, methane, CH₄, is:
H

H - C - H

H
The answer is:
It will float
