Question

15 multiple choice 1 point which of the following indicates a chemical change? melting ice cutting paper boiling water rusting iron

Explanation:

A chemical change results in a new substance being formed. Melting ice, cutting paper, and boiling water are physical changes as they only change the state or form of the substance without creating a new substance. Rusting iron is a chemical change because iron reacts with oxygen to form iron oxide (rust), a new substance.

Answer:

D. Rusting iron
