Question

KCl + ….. → KNO3 + …… ZnSO4 + …… → ZnCl2 + ….. Ba(NO3)2 + ….. → KNO3 + ….. LiCl + ….. → NaCl + ….. HCl + ….. → CO2 + H2O + ….

Answer 1

1. KCl + AgNO3 -> KNO3 + AgCl↓

2.ZnSO4 + BaCl2 -> ZnCl2 + BaSO4↓

3.Ba(NO3)2 + K2SO4 -> 2KNO3 + BaSO4↓

4.3LiCl + Na3PO4 -> 3NaCl + Li3PO4↓

5.2HCl +Na2CO3 -> CO2 + H20 + 2NaCl

Answer 2

To balance the chemical equations you provided, I will fill in the missing compounds:

1. KCl + AgNO3 → KNO3 + AgCl (Potassium chloride + Silver nitrate → Potassium nitrate + Silver chloride)

2. ZnSO4 + 2 HCl → ZnCl2 + H2SO4 (Zinc sulfate + Hydrochloric acid → Zinc chloride + Sulfuric acid)

3. Ba(NO3)2 + K2SO4 → 2 KNO3 + BaSO4 (Barium nitrate + Potassium sulfate → Potassium nitrate + Barium sulfate)

4. LiCl + NaNO3 → LiNO3 + NaCl (Lithium chloride + Sodium nitrate → Lithium nitrate + Sodium chloride)

5. 2 HCl + Na2CO3 → CO2 + H2O + 2 NaCl (Hydrochloric acid + Sodium carbonate → Carbon dioxide + Water + Sodium chloride)

Please note that the above-balanced equations are based on typical reactions and balanced using stoichiometry principles.
