"(NH4)2SO3" is the formula for the compound among the following choices given in the question that is formed from the following polyatomic ions: NH4+, SO32-. The correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that has come to your help.

Answer: The correct option is C) \((NH_4)_2SO_3\) .

Explanation: The given ions are ammonium ion with +1 charge and sulfite ion with -2 charge. When the ions combined to form a compound then over all charge becomes. The over all charge becomes zero only if the positive charge equals to the negative charge.

As the ammonium ion has +1 charge and the sulfite ion has -2 charge, two ammonium ions are required for each sulfite ion. Since two ions of ammonium ion are required for each sulfite ion, the subscript of ammonium ion will be 2 and that of sulfite ion is 1. If the subscript is 1 then its not written.

Hence, the compound formula will be \((NH_4)_2SO_3\) and the correct option is C.
