What is the main difference between a homogeneous mixture and a heterogeneous mixture?

a.
the number of ingredients in each will differ.

b.
the components of a homogeneous mixture are evenly distributed.

c.
a homogeneous mixture is easier to make.

d.
the components of a heterogeneous mixture are spaced evenly throughout.

The answer is The components of a homogeneous mixture are evenly distributed.

In a homogeneous mixture, all components are evenly distributed. They are known as solutions. In a heterogeneous mixture, components are not evenly distributed. It consists of visibly different components. For example, milk is the homogeneous mixture, you cannot see its particles. But milk and cereals are the heterogeneous mixtures.
