What is the formula for the compound formed from the following polyatomic ions: nh4+, so32-?
a. nh4so3
b. nh6so3
c. (nh4)2so3
d. nh4(so3)2

The correct option is C) .

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 and the correct option is C.

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

d.) circle motion requires a force to give it a centripetal acceleration.
