Answer

Brief Explanations:

A chemical change results in a new substance being formed with different chemical properties. Burning toast, a candle being lit, a car rusting, a white - cloudy substance forming after mixing two clear solutions, and leaves changing color in October involve chemical reactions that produce new substances. Wax melting, water boiling, crushing a rock with a hammer, and mixing yellow and blue paints are physical changes where no new chemical substances are formed.

Answer:

Evidence of a chemical change: Burning toast, A candle being lit, A car rusting, A white cloudy substance occurs after mixing two clear solutions, Leaves changing color in October No evidence for a chemical change: Wax melting, Water boiling, Crushing a rock with a hammer, Yellow and blue paints mixed together
