c) Air          

Heterogeneous mixture

d) Soil

e) Blood

Explanation:

Mixture:

mixture is made up of different atoms and can be separated into its component by physical mean.

•The properties of the mixture are not same and contains the properties of all those component present in it.

•mixture is a combination of one or more Pure substances and can be separated by simple physical methods.

•it have varying boiling and melting point.

There are two types of mixture

Homogeneous mixture and heterogeneous mixture

Homogeneous mixture:

It have same uniform appearance and the different components cannot be distinguished by naked eye.

Heterogeneous mixture:

It do not have uniform appearance and the different components of the mixture can be distinguished and observed by naked eye.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
