which is not a chemical change?
ingredients for a cake are stirred together
a bar of iron rusts
an egg is cooked
a piece of wood is burned

Explanation:

A chemical change produces a new substance, while a physical change only alters form/state without new matter. Stirring cake ingredients only mixes them; no new substance is formed. Rusting, cooking an egg, and burning wood all create new chemical substances.

Answer:

ingredients for a cake are stirred together
