Answer:
Mixture is a combination or aggregate of two or more components. A mixture can be homogenous or hetrogenous depending upon the components present in it. A homogenous mixture is the one which is made of only one type of component. A hetrogenous mixture is the one which is made up of two or more types of components. An air is a mixture of gaseous elements and compounds that interact but are not bound to each other. Therefore, air is a hetrogenous mixture of gases.
