Water is made up of two hydrogen atoms and one oxygen atom.

Q. In water, the angle between the atoms of Hydrogen and one atom of Oxygen is

Q. Hydrogen combines with oxygen in a 1:8 weight ratio to form water. If every molecule of water contains two atoms of hydrogen and one atom of oxygen, an atom of oxygen must weigh:

Q. Assertion :Molecular formula of water is $\left(H_{2}O\right)$. Reason: One molecule of water contains two atoms of hydrogen and one atom of oxygen.

Q. Assertion :In the formation of water molecule, both hydrogen and oxygen atoms attain octet of electrons. Reason: Oxygen atom forms two ionic or electrovalent bonds with two hydrogen atoms.

Q. Water is formed by the chemical combination of hydrogen and oxygen.
A molecule of water consists of 2 atoms of hydrogen and 1 atom of oxygen, combined chemically. Figure 1 represents the molecules in liquid water (black – oxygen atom; gray – hydrogen atom).


Which of the following represents water molecules after liquid water is vaporized on boiling?

(a) (b) (c)
