Question

write chemical formula of all the compounds that can be formed by the combination of following ions
Ca2+,k+,Fe3+,Cl- ,SO2-AND4 ATOM
+POSITIVE CHARGE
-NEGATIVE CHARGE

Answer 1

The following compounds are can be made from these above given ions and 4 atoms.

The ions can be divided as cations which are Ca++, Fe+++, K+ and the anions include Cl-, SO2- AND SO4-.

So they including will make CaSO4, CaSO2, CaCl2, FeCl3, Fe2 (SO4)3, Fe2 (SO2)3, KCl, K2SO4 and K2SO2.

The reaction actually takes place by ionization and delivers rapid compound mixing and reaction.
