Actually, there are actually an incredible number of chemical compounds known, and plenty of extra hundreds of thousands are feasible but have not still been found or synthesized. Most substances present in character—for instance Wooden, soil, and rocks—are mixtures of chemical compounds. These substances can be divided into their constituent compounds by physical strategies, which might be methods that do not change the way during which atoms are aggregated inside the compounds.
