Question

•Zn + CuSO4 → •CaCO3 + HCl → •BaCl2 + H2SO4 → •Ba(NO3)2 + K2SO4 → •NaCl + AgNO3 → •AlCl3 + NaOH →

Answer 1

Ответ:

Zn + CuSO4 = ZnSO4 + Cu

CaCO3 + 2HCl = CaCl2 + CO2 + H2O

BaCl2 + H2SO4 = BaSO4 + 2HCl

Ba(NO3)2 + K2SO4 = BaSO4 + 2KNO3

NaCl + AgNO3 = NaNO3 + AgCl

AlCl3 + 6NaOH = Na3[Al(OH)6] + 3NaCl

Answer 2

Let's balance the chemical equations step by step:

1. Zn + CuSO4 → ZnSO4 + Cu (Zinc reacts with Copper(II) sulfate to form Zinc sulfate and Copper)

2. CaCO3 + 2HCl → CaCl2 + CO2 + H2O (Calcium carbonate reacts with Hydrochloric acid to form Calcium chloride, Carbon dioxide, and Water)

3. BaCl2 + H2SO4 → BaSO4 + 2HCl (Barium chloride reacts with Sulfuric acid to form Barium sulfate and Hydrochloric acid)

4. Ba(NO3)2 + K2SO4 → BaSO4 + 2KNO3 (Barium nitrate reacts with Potassium sulfate to form Barium sulfate and Potassium nitrate)

5. NaCl + AgNO3 → AgCl + NaNO3 (Sodium chloride reacts with Silver nitrate to form Silver chloride and Sodium nitrate)

6. AlCl3 + 3NaOH → Al(OH)3 + 3NaCl (Aluminum chloride reacts with Sodium hydroxide to form Aluminum hydroxide and Sodium chloride)

Please note that I've balanced the equations by ensuring that the number of atoms of each element on both sides of the equation is the same.
