Is jello a mixture or pure substance?

* Multiple components: Jello is made from gelatin, water, sugar, and flavoring. These are distinct substances.

* Variable composition: You can change the amount of each ingredient, resulting in different flavors and consistencies of jello.

* Separation: You could potentially separate the components of jello by filtering out the water and perhaps using a centrifuge to separate the gelatin from the sugar.

Therefore, since jello has multiple components and a variable composition, it's classified as a mixture.
