Question

1. of the properties listed below for the metal magnesium, which would be a chemical property?

□ melting point: 651°c
□ silvery - white solid
☑ ignites when heated
□ density: 1.738 g/ml

Explanation:

Chemical properties describe how a substance changes into a new substance via a chemical reaction. Physical properties are observable without altering the substance's chemical identity. Melting point, color, and density are physical properties. Igniting when heated involves magnesium reacting with oxygen to form magnesium oxide, a new substance, so this is a chemical property.

Answer:

✓ ignites when heated
