Question

There are three main types of mixtures. Which is a heterogeneous mixture

Answer 1

Heterogeneous -
The hetero prefix means something like "different," and it makes sense because there are different stuff mixed up in a heterogeneous mixture. So there are different components that haven't been bonded together.

Answer 2

The "homo" prefix means "same," so a homogeneous mixture is one solution, the same all the way through.
