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]

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.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
