Question

I need to balance this equation by redox reactions with half reactions method
NH4ClO4 + Al --> Al2O3 + AlCl3 + NO

Answer 1

IT wont balance ever, by any method. You have H on the left, not on the right.

Answer 2

Bob is wrong, by half reactions the hydrogen will balance out with the addition of H2O on the right hand side... i'm doing this problem myself and having trouble separating into half reactions in the first place
