Answer:
Mixture in chemistry terminology refers to a mixture of two or more components (elements, compounds or others) in such a way that there are no specific proportions. Moreover, the constituent components retain their characteristic properties to a greater extent. Mixtures do not have fixed boiling or melting points, rather they boil or melt over temperature ranges. Mixtures can be in the solid, liquid or gas state.
Compounds on the other hand are combinations of two or more elements combined in specific proportions e.g. 2 atoms of hydrogen and one of oxygen element combine to form water H2O. In forming a compound, the constituent materials lose their characteristic properties to a greater extent e.g. Hydrogen is combustible, and oxygen helps in combustion whereas water is neither combustible nor helps in combustion. Compounds, if do not have any impurities, melt and boil at fixed temperatures. Compounds also exist in the solid, liquid and gas states.
