Homework Help: CHEMISTRY

Posted by Vanessa on Thursday, April 22, 2010 at 5:07pm.

Hello, I am trying to balance this redox reaction WITHOUT using the half-reaction method. Here is the unbalanced equation:

MnO4 -(aq) + Zn(s)--> Mn 2+(aq) + Zn 2+(aq)

It looks as if both elements are being oxidized. The answer is supposed to be:

2MnO4 -(aq) + 16H +(aq) + 5Zn(s) --> 2Mn 2+(aq) + 8H2O(l) + 5Zn 2+(aq)

Thank you!
