First, We define a heterogeneous mixture:
It's a mixture in which the composition is not uniform throughout the mixture. It consists of two or more phases.
Soda with Ice, e.g. Coke with ice is a good choice, they form a heterogeneous mixture, they are in two distinct phases of matter (Ice is solid, Coke is liquid).
We have here 2 components and when we put them for example into a glass, we can look at the different phases formed.
Number of components: 2 (soda and ice)
Phases: 2 ( one solid and another one liquid)
Pizza is made up of different ingredients, which are each separate component. We consider it as a heterogeneous mixture because of that, and those components form different phases.
Number of components: we have many here. It depends on what you used to make the pizza up.
Phases: we have many phases, but mainly solid and liquid phases.
