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.
