KOH + NH4Cl = Na3PO4 + HCl = ZnO + K2CO3 = KBr + Cl2 = разложение FeCO3 =

Here are the balanced chemical reactions for the equations you provided:

1. KOH + NH₄Cl → KCl + NH₃ + H₂O

   • This is an acid-base reaction where potassium hydroxide reacts with ammonium chloride to produce potassium chloride, ammonia, and water.

2. Na₃PO₄ + HCl → NaCl + H₃PO₄

   • In this neutralization reaction, sodium phosphate reacts with hydrochloric acid to produce sodium chloride and phosphoric acid.

3. ZnO + K₂CO₃ → ZnCO₃ + K₂O

   • This reaction shows zinc oxide reacting with potassium carbonate, forming zinc carbonate and potassium oxide.

4. KBr + Cl₂ → KCl + Br₂

   • In this halogen displacement reaction, potassium bromide reacts with chlorine gas to produce potassium chloride and bromine.

5. FeCO₃ → FeO + CO₂

   • This is the decomposition reaction of iron(II) carbonate, which breaks down into iron(II) oxide and carbon dioxide upon heating.
