Question

1. check the box if the statement describes a chemical property or a physical property.

chemical property physical property
malleability
boiling point
color
ductility
toxicity
density
reactivity
flammability

Explanation:

Physical properties can be observed or measured without changing the substance's chemical composition. Chemical properties describe a substance's ability to undergo chemical changes. Malleability, boiling - point, color, ductility, density are physical as they don't involve chemical change. Toxicity, reactivity, flammability involve chemical reactions and changes in the substance's composition.

Answer:

malleability: Physical property
boiling point: Physical property
color: Physical property
ductility: Physical property
toxicity: Chemical property
density: Physical property
reactivity: Chemical property
flammability: Chemical property
