Question

Density, solubility, hardness, melting point, freezing point, color, texture conductivity.

a) density, solubility, hardness
b) melting point, freezing point, color
c) texture conductivity, color, hardness
d) solubility, melting point, texture

Answer 1

Flammability is the only chemical property listed, as it involves a substance's ability to burn and change its chemical structure. Density, melting point, and color are physical properties.

Step-by-step explanation:

The question is asking which option lists only chemical properties. A chemical property is a characteristic of a substance that can change its chemical structure. Choices provided include properties like density, melting point, color, and flammability. Flammability is a chemical property because it pertains to a substance's ability to ignite and undergo combustion. In contrast, density, melting point, and color are considered physical properties because they can be measured or observed without changing the substance's chemical identity.

Based on the information provided and the definition of chemical properties, only flammability fits the criteria as a chemical property, meaning that the correct answers to both exercises would be:

• Exercise 3.5.1B: a. flammability
• Exercise 1.4.1B: 1. flammability
