C) K4MnO
D) KMnO4

The following list contains some common polyatomic ions Using the charge on these ions and the idea of valence predict the formulas for the compound formed from class=

Respuesta :

Answer:  or Sodium carbonate.

              or Potassium permanganate

Explanation: ion carries 1 + charge whereas carbonate ion carries overall charge of -2. So for every carbonate ion, two sodium ions combine to balance the charges and thus form a stable compound,

Potassium ion carries 1 + charge where as permanganate ion carries overall charge of -1. So for every permanganate ion, one potassium ion combines to balance the charges and thus form a stable compound,  Explanation:
