To solve the given chemical equations, we need to identify the products:

a) \( \text{NH}_3 + \text{H}_2\text{SO}_4 (\text{конц.}) \rightarrow \text{(NH}_4)_2\text{SO}_4 \)

When concentrated sulfuric acid reacts with ammonia, ammonium sulfate is produced.

b) \( \text{NH}_3 + \text{HCl} (\text{конц.}) \rightarrow \text{NH}_4\text{Cl} \)

Ammonia reacts with concentrated hydrochloric acid to form ammonium chloride.

c) \( \text{NH}_3 + \text{HNO}_3 (\text{конц.}) \rightarrow \text{NH}_4\text{NO}_3 \)

Concentrated nitric acid reacting with ammonia results in ammonium nitrate.

These reactions involve the neutralization of ammonia with the corresponding acids to form ammonium salts.
