Question

1. look at the picture. then, answer the question.

the density of epibatidine is 1.2 g/ml. is density a physical or chemical property?
chemical property
physical property

Explanation:

Physical properties are characteristics that can be observed or measured without changing the substance's chemical composition. Density is calculated as mass per unit volume ($\text{density}=\frac{\text{mass}}{\text{volume}}$) and does not involve a chemical change. Chemical properties involve changes in the substance's chemical structure (e.g., reactivity, flammability). Since density measurement doesn't alter the chemical makeup of epibatidine, it's a physical property.

Answer:

physical property
