An explanation of what water is.

Most people when you ask them refer to water as “H2O” or also also would call it Hydrogen Oxide which again is wrong.
As water H2O=2 Hydrogen molecules, 1 Oxygen molecule.
This would mean rather than being called Hydrogen Oxide as most people would think it is called the actual two names of water is:
Hydrogen Hydroxide:This fits in with the chemical formula of H2O and the name shows it as well as it tells us that there is “Hydrogen and 1 Oxygen molecule.
The other is called Dihydrogen Monoxide. Though this is technically correct this chemical name is rarely used as it is like a hoax it is considered not right, though is technically correct.
I would just stick to calling it water in a lesson unless you are writing chemical equations. Or if you just want to look clever then feel free to call it any of these two.
EDIT – The IUPAC name given for water is oxidane though water is also just as commonly used.
