Compare and contrast heterogeneous and homogeneous mixtures

Hetero = many and homo = one.

Explanation:

Heterogeneous:

In the Heterogenous mixture, the components that are present in the mixture are not distributed uniformly. There are two or more than two phases present in a heterogeneous mixture. Examples of the heterogeneous mixture are - cereal in milk, gravel, pizza.

while

Homogeneous mixture:

In Homogeneous mixture, the components that are present in the mixture are distributed uniformly throughout the solution. There is only one phase present in a homogenous type of solution.   Examples of the homogenous mixture are- air, rainwater, steel.

Determine the  wavelength of light emitted when an electron  in an li2+ ion  makes a transition from an orbital with n  =  6 to an orbital with n  = 5.

The density would be 1.622
