Bonds in a molecule of water are covalent bonds because the hydrogen and oxygen molecules share electrons.
The smallest fundamental unit of a covalent compound is called a molecule. It is formed when two or more atoms share electrons to become stable.
An example of this general type of molecule that you could find at home is water, which is a polar molecule. Water consists of two hydrogen atoms covalently bonded to one oxygen atom, resulting in an uneven distribution of charge and making it a polar molecule.
Two hydrogen atoms need to be combined with one oxygen atom to form a molecule of water (H2O). Or you could have two hydrogen to two oxygen atoms, forming hydrogen peroxide (H2O2) but this is unstable and decomposes back to water and oxygen gas.
pure water evaporates faster because it has a higher vapour pressure than salt water. Raoult's Law. The attraction between salt ions and water is stronger than that of water molecules. It therefore takes more energy to separate a water molecule from salt, that a water molecule from another water molecule.
Water is a polar molecule.
The molecule of water remain unchanged, and also the percentage of hydrogen.

NH3 (ammonia) is less stable than water due to its lower boiling point and reactivity with acids. Water is a more stable molecule due to its strong hydrogen bonding and overall lower reactivity compared to ammonia.

No. Water is called fresh simply when it does not have too much salt in it. Fresh water could still be contaminated with toxins or harmful organisms.
This would normally be fresh water, but on some occasions, they can be salt or brackish.
A third hydrogen atom cannot join a water molecule (H2O) to form H3O in the same way because water is a stable molecule with a bent structure due to the two lone pairs of electrons on the oxygen atom. While H3O does exist as the hydronium ion, it forms under specific conditions when an additional hydrogen ion (H+) combines with a water molecule. However, this is a transient state and does not represent a stable, neutral molecule like H2O.
The stable is rice. Cambodian (Khmer) food uses a variety of fresh water and sea fish and meats, fresh herbs and pickles.
A shallow body of fresh water could be described as a pond.
