Question

Of carbon disulfide, rubber latex, and petroleum spirit, which are pure substances, and which are mixtures?

Answer 1

All except carbon disulfide, `CS_2`, are mixtures......

Explanation:

Petroleum is a mixture of isomers; even the petroleum spirit supplied in the lab is a mixture of `C_4-C_6` hydrocarbons. Rubber latex is a polymer, and vulcanizing solution is a proprietary mixture of sulfur and other materials......

On other hand, `CS_2` is a volatile solvent with a particularly foul odour, and is particularly flammable.
