Question

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?

Answer 1

Answer:

When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. ... In this oxidation, a molecule of hydrogen gas is ionized to two electrons and two protons.

Answer 2

Answer:

A water molecule is made up of two hydrogen atoms and one oxygen atom. A single oxygen atom contains six electrons in its outer shell, which can hold a total of eight electrons. When two hydrogen atoms are bound to an oxygen atom, the outer electron shell of oxygen is filled
