Final answer:
The empirical formulas for four ionic compounds given the ions MnO4-, BrO3-, Fe2+, and Pb4+ are Fe(MnO4)2 for Iron(II) permanganate, Pb(BrO3)4 for Lead(IV) bromate, Fe(BrO3)2 for Iron(II) bromate, and Pb(MnO4)4 for Lead(IV) permanganate.
Step-by-step explanation:
The task is to write the empirical formula for ionic compounds that could be formed from specific ions. For the ions provided (MnO4−, BrO3−, Fe2+, Pb4+), we would pair each anion with a cation to neutralize the charge and create a stable ionic compound. Here are the empirical formulas for four possible ionic compounds:
- Fe(MnO4)2: Iron(II) permanganate
- Pb(BrO3)4: Lead(IV) bromate
- Fe(BrO3)2: Iron(II) bromate
- Pb(MnO4)4: Lead(IV) permanganate
Each formula is created by balancing the charges of the cations and anions to ensure that the overall charge of the compound is zero.
