50 items of chemistry in everyday life & chemical composition
What is Chemical Composition?
Chemical composition can be defined as the arrangement, ratio, and type of atoms in molecules of chemical substances. The chemical composition will vary if chemicals are subtracted or added from a substance. That is when the ratio of the substance changes or when chemical changes occur in the chemicals.
It is the chemical composition of a substance that determines the properties of the substance. We can conclude from here that the way atoms are put together, the density, colour, strength and other properties are determined.
