Question

the reactivity of iron with oxygen the color of aluminum wire the flammability of ether the luster of silver jewelry the melting point of butter the smell of ginger the explosiveness of fireworks physical property chemical property

Explanation:

Physical properties can be observed or measured without changing the substance's chemical composition. Chemical properties are observed when a substance undergoes a chemical change. The color, luster, smell, and melting - point are physical as they don't involve chemical change. Reactivity, flammability, and explosiveness involve chemical changes.

Answer:

Physical property: the color of aluminum wire, the luster of silver jewelry, the smell of ginger, the melting point of butter
Chemical property: the reactivity of iron with oxygen, the flammability of ether, the explosiveness of fireworks
