Question

Carbon forms molecular compounds with some elements from Group 16. Two of these compounds are carbon dioxide, CO2, and carbon disulfide, CS2.

Carbon dioxide is a colorless, odorless gas at room temperature. At standard temperature and pressure, CO2(s) changes directly to CO2(g).

Carbon disulfide is formed by a direct reaction of carbon and sulfur. At room temperature, CS2 is a colorless liquid with an offensive odor. Carbon disulfide vapors are flammable.

59 Identify one physical property and one chemical property of CS2. [1]

Answer 1

The physical property of carbon disulfide is that at room temperature, CS2 is a colorless liquid with an offensive odor. The chemical property of carbon disulfide is that it is formed by a direct reaction of carbon and sulfur.

Answer 2

Answer: Physical property of $CS_2$ is state of matter (liquid) and it is a chemical compound.

Explanation:

Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed.

Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc.

Carbon disulfide $(CS_2)$ is the compound which is formed by the chemical combination of carbon and sulfur atoms. The equation for this follows:

$C+2S\rightarrow CS_2$

The chemical property of carbon disulfide is different from that of carbon and sulfur. Thus, this is a chemical compound.

It is given, that this compound is a colorless liquid, which means that the state of this compound is liquid state.

Hence, physical property of $CS_2$ is state of matter (liquid) and it is a chemical compound.
