It is a pure substance that can be decomposed into simpler substances by some suitable chemical technique. A compound is formed by combination of two or more elements in a definite proportion. For example, water is a compound of hydrogen and oxygen elements present in..

A compound is a pure substance that is formed by the combination of atoms of two or more elements. The atom in a compound is chemically combined in a fixed and constant proportion. When compounds are formed, atoms of two or more elements combine chemically, by either..

The oxygen percent decreases as the elevation increases. If h represents the elevation, find the oxygen percentage that shows the compound inequality 25000 < h ≤ 50000 from the table. => 14% or 6% or 50% or 35%..

Chlorine combines with free hydrogen to form hydrogen chloride. It can also react with the hydrogen present in other compounds such as water, ammonia, hydrocarbon, hydrogen sulphide e..

Introduction - All elements in the periodic table have been classified as metals and non-metals. The non-metals are placed on the right hand side of the periodic table. Non-metals are simple small molecules that are mostly gases. Elements between metals and non-metals are regarded as semi-metals an..
