A compound is a substance that includes two or more elements nlinux.orgically unified in a fixed proportion. The aspects carbon and hydrogen incorporate to create many kind of different compounds. One of the simplest is referred to as methane, in which tright here are constantly 4 times as many kind of hydrogen pshort articles as carbon pwrite-ups. Methane is a pure substance bereason it always has the very same composition. However, it is not an element because it can be broken down right into less complicated substances—carbon and hydrogen.
Recontact that the components of a mixture deserve to be separated from one an additional by physical means. This is not true for a compound. Table salt is a compound consisting of equal components of the elements sodium and also chlorine. Salt cannot be separated into its 2 elements by filtering, distillation, or any type of other physical process. Salt and also various other compounds can just be dewritten into their elements by a nlinux.orgical process. A nlinux.orgical change is a change that produces issue through a various composition. Many compounds have the right to be decreated into their facets by heating. When sugar is heated, it decomposes into carbon and water. Water is still a compound, yet one which cannot be broken dvery own right into hydrogen and oxygen by heating. Instead, the passage of an electric current through water will produce hydrogen and also oxygen gases.

The properties of compounds are mostly very different than the properties of the facets from which the compound is developed. Sodium is a very reactive soft metal that cannot be exposed to air or water. Chlorine is a deadly gas. The compound sodium chloride is a white solid which is vital for all living points (watch below).
