### class example

**Sun Feb 16, 2020 12:56 pm**Just to clarify, in class Lavelle used the example:

8H+ + MnO4- + 5e- = Mn+2 + 4H2O where he said Mn is reduced from +7 to +2

Mn is initially +7 because O4 is is -8 and in order for the overall molecule to have a negative charge, Mn has to be +7 right? Thanks in advance!
