Explanation:

25. Binary ionic compounds: They are known as the compounds which contains a cation formed from a metal and an anion formed from a non-metal or a polyatomic anion. For example : Barium sulfate

Ba : +2 ( metal of group II-A)

[tex]SO_4[/tex] : -2 ( sulfate)

These two ions combine to form a binary ionic compound having formula [tex]BaSO_4[/tex]

Binary Molecular compounds: They are known as the compounds which contain two or more non-metals that are bonded covalently. In these compounds, no ions are present because the electrons are shared by the atoms. Examples are: [tex]PCl_3[/tex] : phosphorous trichloride

[tex]SO_2[/tex] : sulfur dioxide

26. The general chemical formula for an acid is HX where H is the hydrogen and X is the non-metal or polyatomic ions. Examples of acids are:

HF : Hydrofluoric acid

[tex]H_2SO_4[/tex] : Sulfuric acid
