Justin is making a snack. he toasts a piece of bread and spreads peanut butter and jelly on it. then he cuts an apple into several slices and adds these to his plate. next, justin mixes a scoop of lemonade powder into a glass of water, mixes it, and adds ice.

how many chemical changes occurred in this scenario?

one

Explanation:

The chemical change that occurred was the toasting of the bread. This caused the bread to be heated and cooked, using fire to change it into a new substance. This cannot be reversed because you cannot make toast back into bread. All of the other changes were physical changes and did not change the identity of the substance.
