The redox reaction below occurs in acidic solution. Balance it with the smallest whole number coefficients and determine the coefficient for H+. MnO4(aq) + HNO2(aq) > Mn2+(aq) + NO3(aq)
when i did it..i got the answer as1...but im not to sure..help?
1. 3
2. 5
3. 1
4. 4
5. 2

How can you not be too sure? The equation is either balanced or it isn't and you know when you finish if it is right or not. I get 1 H^+ too. And I know that's right because the equation balances
1. atoms.
2. charge.
3. electron change. 
Balance this equation in acidic solution Mno4+Clo3=Clo4+Mn2+
