Is tuna casserole a heterogeneous mixture?

Yes, tuna casserole is a heterogeneous mixture. Here's why:

* Heterogeneous mixtures have components that are not evenly distributed throughout the mixture.

* Tuna casserole typically includes ingredients like:

* Tuna: Solid chunks of fish.

* Pasta: Solid noodles.

* Cream of mushroom soup: A creamy, often lumpy sauce.

* Vegetables: Pieces of peas, carrots, or other vegetables.

* Cheese: Often melted and distributed unevenly.

Because these ingredients are not uniformly dispersed, a single spoonful of tuna casserole might contain different amounts of each component. This uneven distribution makes it a heterogeneous mixture.
