What you think is correct:

H2SO4 + NH3 ----> (NH4)2SO4

You could dissolve ammonia (NH3) in water (H2O) to get

NH3 + H2O ----> NH4OH

Now add the acid (H2SO4) to the aqueous solution of ammonia.

H2SO4 + 2NH4OH ---> (NH4)2SO4 + 2H2O

(Often, when we refer to a reaction with "ammonia" involved, we can treat it as "a solution of ammonia in water" without giving any importance to the water it is dissolved in...so by saying NH3 we actually mean NH4OH.)

Your teacher probably had the ammonia solution in mind when he/she told you that there'd be H2O on the product side. Otherwise, dry ammonia itself (NH3) reacts as

H2SO4 + NH3 ----> (NH4)2SO4 , which is perfectly balanced and correct.

H2so4 Nh3

Nh3 H2so4

Hey the reaction is SO3 + H2O ==> H2SO4 You are balancing the wrong reaction!

I choose your answer over the teacher's. Water is not generated when an anhydrous base is used. If she wanted to use NH₄OH instead of ammonia, then water would have been a product.

how above equation is balanced?
