Please help me with this one...

What is the oxidizing agent in the following redox reaction:

HNO3(aq) + K2CrO4(aq) + Fe(NO3)2(aq) ->

KNO3(aq) + Fe(NO3)3(aq) + Cr(NO3)3(aq) + H2O(l)

?

First one: Cr starts at +6 each and ends at +3. Fe(II) starts at +2 and ends at +3.
Oxidation is the loss of electrons.
