This formula indies that a molecule of acetic acid (Figure 6) contains two carbon atoms, four hydrogen atoms, and two oxygen atoms. The ratio of atoms is 2:4:2. Dividing by the lowest common denominator (2) gives the simplest, whole-nuer ratio of atoms, 1:2:1, so the empirical formula is CH 2 O. Note that a molecular formula is always a whole-nuer multiple of an empirical formula.

Carbon - Wikipedia
Carbon (from Latin: carbo "coal") is a chemical element with the syol C and atomic nuer 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.It belongs to group 14 of the periodic table. Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a half-life of about 5,730 years.

An example of a simple chemical reaction is the breaking down of hydrogen peroxide molecules, each of which consists of two hydrogen atoms bonded to two oxygen atoms (H 2 O 2). The reactant hydrogen peroxide is broken down into water, containing one oxygen atom bound to two hydrogen atoms (H 2 O), and oxygen, which consists of two bonded oxygen atoms (O 2 ).
