b. HF
c. H2S


Sagot :

Explanation:

A compound containing only two elements is called a binary compound.

(a). The compound HCN contains a hydrogen ion and cyanide ion. Hence, the name of HCN is hydrogen cyanide.

An aqueous solution of hydrogen cyanide is known as hydrogen cyanide solution.

(b). The compound HF contains a hydrogen ion and a fluorine ion. The suffix -ide will be added to its name. So, the name of this compound is hydrogen fluoride.

An aqueous solution of HF is known as hydrogen fluoride.

(c). The compound [tex]H_{2}S[/tex] contains two hydrogen atoms and one sulfur atom. The suffix -ide will be added to its name. So, the name of this compound is hydrogen sulfide.

An aqueous solution of this compound is known as hydrogen sulfide solution.
