write out the balanced equation when Iron(II) sulfate, potassium permanganate, and sulfuric acid react to form Iron (III) sulfate, manganese (II) sulfate, Potassium sulfate, and water.
Is your problem in balancing these. Here is a site that will help and I will get you started. You need to learn to do these by yourself. #5,6,7 should be of help to you.

FeSO4 + KMnO4 + H2SO4 ==> Fe2(SO4)3 + MnSO4 + K2SO4 + H2O
In this reaction Fe changes oxidation state from +2 on the left to + 3 on the right. Many students don't start this right; the first thing to do is place a coefficient of 2 for FeSO4 so you can compare 2 Fe with 2 Fe. Then Mn on the left is +7 and on the right is +2. Now follow the rules.
To write out the balanced equation for the reaction between Iron(II) sulfate (FeSO4), potassium permanganate (KMnO4), and sulfuric acid (H2SO4), we need to determine the chemical formulas of the products.
The reaction involves the oxidation of iron(II) and the reduction of permanganate. Let's break it down step by step:
1. Determine the products:
- Iron(II) sulfate (FeSO4) will react with potassium permanganate (KMnO4) and sulfuric acid (H2SO4).
- The products will be Iron(III) sulfate (Fe2(SO4)3), manganese(II) sulfate (MnSO4), potassium sulfate (K2SO4), and water (H2O).
2. Write the unbalanced equation:
FeSO4 + KMnO4 + H2SO4 → Fe2(SO4)3 + MnSO4 + K2SO4 + H2O
3. Balance the equation:
Balance the elements one by one. Start with the most complex molecule or the atoms that appear the least number of times.
a. Balance the Fe atoms:
FeSO4 + KMnO4 + H2SO4 → Fe2(SO4)3 + MnSO4 + K2SO4 + H2O
b. Balance the Mn atoms:
FeSO4 + KMnO4 + H2SO4 → Fe2(SO4)3 + MnSO4 + K2SO4 + H2O
c. Balance the S atoms:
FeSO4 + KMnO4 + H2SO4 → Fe2(SO4)3 + MnSO4 + K2SO4 + H2O
d. Balance the O atoms:
FeSO4 + KMnO4 + H2SO4 → Fe2(SO4)3 + MnSO4 + K2SO4 + H2O
e. Finally, balance the H atoms:
FeSO4 + KMnO4 + 2H2SO4 → Fe2(SO4)3 + MnSO4 + K2SO4 + 2H2O
The balanced equation for the reaction is:
3FeSO4 + 2KMnO4 + 2H2SO4 → Fe2(SO4)3 + 2MnSO4 + K2SO4 + 2H2O
