How are mixture and compounds different?
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.
