2) Sakonzerme p-yeep. Cocmabime a) mathrm(Na)_(2) mathrm(CO)_(3)+mathrm(HNO)_(3) arrow b) mathrm(Cu)(mathrm(OH))_(2)+mathrm(HCl) arrow e) mathrm(KOH)+mathrm(H)_(2) mathrm(SO)_(4) arrow

Let's correct the equations and balance them properly:<br /><br />a) \( \mathrm{Na}_{2} \mathrm{CO}_{3} + 2\mathrm{HNO}_{3} \rightarrow 2\mathrm{NaNO}_{3} + \mathrm{H}_{2}\mathrm{O} + \mathrm{CO}_{2} \)<br /><br />b) \( \mathrm{Cu}(\mathrm{OH})_{2} + 2\mathrm{HCl} \rightarrow \mathrm{CuCl}_{2} + 2\mathrm{H}_{2}\mathrm{O} \)<br /><br />c) \( 2\mathrm{KOH} + \mathrm{H}_{2}\mathrm{SO}_{4} \rightarrow \mathrm{K}_{2}\mathrm{SO}_{4} + 2\mathrm{H}_{2}\mathrm{O} \)<br /><br />These are the balanced chemical equations for the given reactions.
