which of these changes is an example of a chemical change?
folding clothes
slicing vegetables
burning jet fuel
inflating a balloon

Explanation:

A chemical change produces new substances, while physical changes only alter shape/state without forming new matter. Folding clothes, slicing vegetables, and inflating a balloon are physical changes (no new substances). Burning jet fuel reacts with oxygen to create new substances like carbon dioxide and water vapor, which is a chemical change.

Answer:

burning jet fuel
