What is the chemical formula of water?

Answer 1

it's H2O
2 hydrogen one oxygen.
the easiest way to undersand why :
in order to be steady,atoms need to have 8 electrones in the last level.
oxygen has 6,so he needs 2 more.
hydrogen has only 1,so he needs 7 more.
two hydrogen atoms bond with 1 oxygen.
puff !
there's water !

Answer 2

H2O or HOH

Atomic weight of water = 18.01528 amu (atomic mass units)

Legitimate alternative chemical names for water are:
Dihydrogen Monoxide
Hydronium Hydroxide
Hydric acid
and
Hydrogen Hydroxide

Answer 3

Water (H2O, HOH) is the most abundant molecule on Earth, composing 70-75% of the Earth's surface as liquid and solid state in addition to being found in the atmosphere as a vapor. It is in dynamic equilibrium between the liquid and vapor states at standard temperature and pressure. At room temperature, it is a nearly colorless, tasteless, and odorless liquid. Many substances dissolve in water and it is commonly referred to as the universal solvent, however, there are many compounds that are essentially, if not completely, insoluble in water. Water is the only pure substance found naturally in all three states of matter.

Answer 4

H2O Two hydrogen molecules to one oxygen

Answer 5

But of course, its H2O - one molecule of water comprises two atoms of hydrogen and one atom of oxygen

Answer 6

H2O
2 hydrogen atoms
1 oxygen atom

Answer 7

H2O (thats two hydrogen atoms and one oxygen atom)

Answer 8

That would be H2O. Two hydrogen, one oxygen.

Answer 9

H-2-O [2parts hydrogen 1part oxygen].

Answer 10

H20
