(NH4)2SO4 + NaOH = NH3 + Na2SO4 + H2O The answer I'm told is: (NH4)2SO4 + 2NaOH = 2NH3 + Na2SO4 + 2H2O I can't understand how this is...?

balanced because on the left side this coefficient of 2 means that there is now: NH4 = 2 SO4 = 1 Na = 2 <-- O=2 <-- H=2 <-- Both coefficients of 2 on the right now mean: NH3=2<-- Na=2 SO4=1 H=4<-- O=2<-- What am I doing wrong? Is it anything to do with, NaOH multiplying everything to 2 instead... show more balanced because on the left side this coefficient of 2 means that there is now:

What am I doing wrong?
Is it anything to do with, NaOH multiplying everything to 2 instead of just the Na?
