Answer:
Hey i got your answer, MARK IT BRAINLIEST
Explanation:
1. Identify the oxidation number of every atom.
Left hand side: Fe = +2; Mn = +7; O = -2
Right hand side: Fe = +3; Mn = +2
2. Determine the change in oxidation number for each atom that changes.
Fe: +2 → +1; Change = +1
Mn: +7 → +2; Change = -5
3. Make the total increase in oxidation number equal to the total decrease in oxidation number.
We need 5 atoms of Fe for every 1 atom of Mn. This gives us total changes of +5 and -5.
4. Place these numbers as coefficients in front of the formulas containing those atoms.
5Fe2++1MnO-4→5Fe3++1Mn2+
5. Balance all remaining atoms other than H and O.
Done.
6. Balance O.
Add enough H2O molecules to the deficient side to balance O.
We have 4 O atoms on the left, so we need 4 H2O on the right.
5Fe2++1MnO-4→5Fe3++1Mn2++4H2O
7. Balance H.
Add enough H+ ions to the deficient side to balance H.
We have 8 H atoms on the right, so we need 8 H+ on the left.
5Fe2++1MnO-4+8H+→5Fe3++1Mn2++4H2O
8. Check that atoms and charges balance.
On the left: : 5 Fe; 1 Mn; 8 H; 4 O
On the right: 5 Fe; 1 Mn; 8H; 4 O
On the left: ll+10ll- 1 + 8 = +17
On the right: +15 + 2mm=+17
The balanced equation is
5Fe2++1MnO-4+8H+→5Fe3++1Mn2++4H2O
