Chemistry -- to Dr.Bob
because its a redox reaction. the number of electrons in the Fe2+ to Fe3+ half-equation must equal the number of electrons in the MnO4 to Mn2+ half-equation, which is 6. Thus you need to have 6 Fe2+ and 6 Fe3+ also. Balance each half-equation first, and then combine the 2. :)
