2) flammability
3) heat of combustion
4) reactivity
5) malleability
6) toxicity

Answer 1

A chemical property is a characteristic or behavior of a substance that indicates its ability to undergo chemical reactions or changes in composition.

Step-by-step explanation:

A chemical property is a characteristic or behavior of a substance that indicates its ability to undergo chemical reactions or changes in composition. It describes how the substance interacts with other substances or energy to form new substances. Some examples of chemical properties include flammability, toxicity, reactivity, and heat of combustion.

For example, flammability is a chemical property because it describes the substance's ability to burn or ignite in the presence of a flame. Toxicity is also a chemical property because it describes the substance's ability to cause harm or poisoning.

On the other hand, physical properties of matter, such as melting point, boiling point, and density, describe the substance's characteristics that can be observed or measured without changing its composition.

Answer 2

1) Compressibility - The measure of a substance's ability to be compressed or reduced in volume.

2) Flammability - The ability of a substance to catch fire and burn.

3) Heat of combustion - The amount of heat released when a specific amount of a substance undergoes complete combustion.

4) Reactivity - The tendency of a substance to undergo chemical reactions.

5) Malleability - The ability of a material to withstand deformation under compressive stress.

6) Toxicity - The degree to which a substance can harm living organisms.

Step-by-step explanation:

Compressibility: Compressibility is a measure of how much a substance can be compressed or reduced in volume under the application of pressure.

Flammability: Flammability refers to a substance's ability to catch fire and burn. This property is crucial for assessing the fire hazard associated with a material, and it is often expressed as a flammable or combustible limit, indicating the concentration range at which a substance can ignite.

Heat of Combustion: The heat of combustion is the amount of heat released when a specific amount of a substance undergoes complete combustion. It is typically measured in energy units per unit mass or volume of the substance. The heat of combustion is a key parameter for understanding the energy content of fuels.

Reactivity: Reactivity is the tendency of a substance to undergo chemical reactions. Highly reactive substances are more likely to participate in chemical transformations, and this property is crucial for understanding the potential hazards and applications of a material.

Malleability: Malleability is the ability of a material to withstand deformation under compressive stress. It is often assessed by measuring the material's ability to undergo plastic deformation without rupture.

Toxicity: Toxicity is the degree to which a substance can harm living organisms. It is an essential consideration in assessing the safety of chemicals and materials, often expressed as LD50 (lethal dose for 50% of the population) or other toxicity measures.
