Here is a good site that shows how to calculate the oxidation states and how to use them to balance a redox equation.
http://www.chemteam.info/Redox/Redox.html
Using redox methods, write the balanced equations for each of the reactions in the appropriate medium.
A) Ca(s) + Cr2O7(Charge 2-) (aq) --> Ca2+ (aq) + 2Cr3+ in acid medium
B) Fe(CN)6(charge 4-) (aq) + Ce(charge 4+) --> Ce(OH)3(s) + Fe(OH)3(s) + CO3(charge 2-) (aq) + NO3charge -)
I have a test on this in 5 days and I'm so lost, so if you could please explain the step by step process you could use for any problems like this that would be AMAZING. Thank you in advance!
