Can compounds be made of the same element
WebA chemical substance has a fixed composition. According to Proust’s inference, “All samples of a compound have the same composition; i.e., all samples have the same proportion, by mass, of the elements present in the compound”. For instance, water is a chemical compound made up of two elements hydrogen (H) and oxygen (O) in a definite ratio.
