Final answer:
Manganese (IV) perbromate does not exist, but formulas for compounds with the permanganate ion and potassium, calcium, and iron can be given as KMnO4, Ca(MnO4)2, and Fe(MnO4)3 respectively. Also provided is a balanced chemical equation for the reaction between the permanganate ion and bromide ion.
Step-by-step explanation:
The student is asking about the formula for Manganese (IV) perbromate. However, there seems to be a misunderstanding because such a compound does not exist. Instead, if we consider the permanganate ion (MnO4−), where manganese has a +7 oxidation state, we can propose formulas for ionic compounds with potassium (K+), calcium (Ca2+), and iron (Fe3+).
- Potassium permanganate: KMnO4
- Calcium permanganate: Ca(MnO4)2
- Iron(III) permanganate: Fe(MnO4)3
Regarding the reaction of aqueous permanganate ion with aqueous bromide ion (Br−), the balanced chemical equation is:
2 MnO4−(aq) + 16 Br−(aq) + 8 H2O(l) → 2 MnO2(s) + 8 BrO3−(aq) + 16 H+(aq)
