    Really struggling to figure out how to do this. I'm doing an access course online, and my tutor is useless. This is the example.

    (ClO3)- is reacted to form Cl2 and in the same reaction NO is reacted to form (NO3)-. Work out the oxidation numbers and then produce the half equations. Combine the pair of half equations obtained to give the full redox equation.

    I already know that the oxidation numbers for Cl are 5 and 0, and for N are 2 and 5, but from there I have no idea what to do!? Any help would be greatly appreciated.

    Write out the two half equations and look at the number of electrons in each equation to see how you would combine them.
