Hydrogen Bond
Water vapor is the least dense form of water, and the molecules are farthest apart from each other. Liquid water is the densest form of water. In ice, molecules form a crystal lattice.
No, molecules that are farthest apart from each other are not called water vapor. Water vapor refers specifically to the gaseous form of water molecules. Molecules that are far apart from each other can simply be part of a gas phase.
Hydrogen Bond
Yes, the molecules in water are close to each other due to the hydrogen bonding between water molecules. This leads to water having a relatively high density and being in liquid form at room temperature.
Molecules are not stuck together: Water vapor Molecules are attracted to each other, but not ordered: Liquid water Molecules are joined in an ordered structure: Ice -Apex-
Yes, water can form hydrogen bonds with itself. Each water molecule can form hydrogen bonds with up to four neighboring water molecules, resulting in a network of hydrogen-bonded water molecules, which gives water its unique properties like high surface tension and cohesion.
Water molecules won't form a solution (are not miscible) in oil. The reason is that water molecules are polar, and oil molecules are not. Water molecules, in an environment of oil, are attracted to each other, and this polar bonding excludes the oil molecules.
Two water molecules are formed by a total of 6 atoms: 2 from each oxygen atom and 1 from each hydrogen atom.
Hydrogen Bonds
Water molecules form hydrogen bonds with each other. This occurs because the oxygen atom in one water molecule is slightly negatively charged, while the hydrogen atoms are slightly positively charged, allowing for attraction between molecules.
NH3
Three molecules of water are lost when a triglyceride is formed. Each water molecule is released during the condensation reaction between a glycerol molecule and three fatty acid molecules to form a triglyceride.
