Question

I need to balance this equation but I have no idea where to start!
NaOH(aq) + NaNO2 (aq) + Al(s) + H2O(1) --> NH3 (aq) + NaAlO2 (aq)

Answer 1

Start by noticing 2 Na's on the left and 1 on the right. This can be fixed by making is 2NaAlO2.

that Al is now easy to fix. now recount :)

aqueous implies a solid dissolved in water
