answered: cwibs

- 2,1

Explanations:- Water is H_2O and from it's formula it is clear that the ratio of H to O moles or atoms is 2:1 means two hydrogen atoms for each oxygen atom. No matter what amount of water we have, the ratio of H atoms to O atoms is always same.

Hence, the answer is 2,1.

The ratio of H and O atoms in water is 2: 1

Further explanation

In a chemical compound, there is the term atom, element, and compound itself.

1. An atom is the smallest material consisting of a nucleus, which contains protons, neutrons, and electrons,2. Elements can be atomic or molecular elements. It can be an atom such as Ag (argon), Fe (Iron). When in the form of molecules it is a combination of atoms of the same type, for example, O₂,3. A molecule is a combination of elemental atoms, can be two.

- If it consists of atoms of the same element called an Element molecule, For example, N₂, Cl₂

- If it consists of atoms of different kinds of elements called molecular Compounds, for example, H₂SO₄, NaOH

There are numbers in the chemical formula of the compound:

1. Numbers indicate the number of atoms written after the element symbol2. The number after the parenthesis shows the number multiplied by the number of atoms in the parenthesis.3. The number before the chemical formula shows the number of molecules behind it. Usually used in the reaction equation

Generally, there are 2 formulas used:

The empirical formula (RE) is the smallest atomic ratio of the constituent elements.Molecular formula (RM) is a formula that shows the number of atomic elements that make up a compound.

(RE) n = RM

In 1 water molecule that has the H₂O formula, according to the numbers in this molecular formula, it is found that:

there are 2 H atoms and 1 O atom, so the ratio of the atoms is:

H: O = 2: 1
