What kind of reaction is mixing tomato sauce and mayonnaise?

Mixing tomato sauce and mayonnaise is not a chemical reaction in the traditional sense. It's a physical change that creates a mixture.

Here's why:

* No new substances are formed: The ingredients (tomato sauce and mayonnaise) retain their individual chemical compositions. They don't chemically react to create something entirely new.

* Only a change in physical properties: The ingredients combine and may alter their texture, appearance, or taste, but not their underlying chemical structure.

Therefore, the "reaction" is simply the act of combining two different substances to create a new mixture.
