I need to equate the following reaction. This exercise seems me a little bit hard to solve in one reaction. So you'd probably have to write down half-reactions. I've tried a couple of times but I'm not quite getting there... The correct coefficients are:4 18 :rarrow:4 8 9 21H2O.
Could someone sketch how the half-reactions should be properly written down, or could construct the logic on how to get to the right coefficients?
Thanks!
