Lots. You didn't specify how big the ice crystal was, so we can't be more specific.
There are roughly 33,000,000,000,000,000,000,000 water molecules in one gram of ice.
zero.
Ice crystals are made up of many water molecules bonded together in a hexagonal lattice structure. Each water molecule in the lattice is connected to four neighboring water molecules through hydrogen bonds, creating a rigid and ordered structure typical of ice.
There is nothing inside one of the open spaces of an ice crystal. Air would show O2 or N2 within the space, which are comparable in size to water molecules. Any water vapor in the spaces would have to show free-roaming water molecules. Therefore the space is filled with nothing.
A 6-sided ice crystal is typically referred to as a hexagonal ice crystal. It forms when water molecules freeze together in a hexagonal pattern due to the molecular structure of water. These crystals are commonly seen in snowflakes.
The molecules in water are not tightly packed as such flow and spread very easily but when the water turns to ice the molecules in the liquid enlarge ans they tightly packed and thus, when water turns to ice new molecules are not formed.
Compared to a solid object's molecules no. Unless the water is ice. Water molecules are more compact than gaseous molecules.
Water is denser than ice.The reason for this is that in liquid water the molecules are disorganized and their is little space between them. In ice the molecules are organized into a hexagonal crystal structure that puts extra space between the molecules.
The answer depends on what the solid is: ice, a hydrate crystal, or something else.
Ice is a type of solid crystal with a hydrogen bond structure. The bonds between water molecules in ice are hydrogen bonds which are weaker than covalent or ionic bonds. The crystal structure of ice is hexagonal.
can you keep water from expanding when it freezes?
The most common ice crystal shape is a hexagonal prism with flat, hexagonal faces. These ice crystals form due to the hexagonal structure of water molecules when they freeze.
Water and ice can be reversible because they both consist of the same molecules, H2O. When water is cooled down to its freezing point, it forms an orderly crystal lattice structure, resulting in ice. Conversely, when ice is heated to its melting point, the crystal lattice breaks down, turning it back into water.
