Question

4. Завершите уравнения возможных реакций. K+CuSO4→____________________________________ KOH+H2SO4→_________________________________ NaOH+ZnCI2→_________________________________ Ba(OH)2+CO2→_________________________________ Zn(OH)2+K2O→_________________________________ Fe(OH)2+ZnCl2→________________________________

Answer 1

Ответ:

Объяснение:

2K + CuSO4 = K2SO4 + Cu↓

2KOH + H2SO4 = K2SO4 + 2H2O

2NaOH + ZnCl2 = Zn(OH)2↓ + 2NaCl

Ba(OH)2 + CO2 = BaCO3↓ + H2O

Zn(OH)2 + K2O = реакция не идёт

Fe(OH)2 + ZnCl2 = реакция не идёт

Answer 2

K CuSO4 → K2SO4 + Cu

The reaction between potassium (K) and copper sulfate (CuSO4) produces potassium sulfate (K2SO4) and copper (Cu) [[1]].

KOH H2SO4 → K2SO4 + H2O

The reaction between potassium hydroxide (KOH) and sulfuric acid (H2SO4) produces potassium sulfate (K2SO4) and water (H2O) [[2]].

NaOH ZnCl2 → NaCl + Zn(OH)2

The reaction between sodium hydroxide (NaOH) and zinc chloride (ZnCl2) produces sodium chloride (NaCl) and zinc hydroxide (Zn(OH)2) [[3]].

Ba(OH)2 CO2 → BaCO3 + H2O

The reaction between barium hydroxide (Ba(OH)2) and carbon dioxide (CO2) produces barium carbonate (BaCO3) and water (H2O) [[4]].

Zn(OH)2 K2O → ZnO + H2O + KOH

The reaction between zinc hydroxide (Zn(OH)2) and potassium oxide (K2O) produces zinc oxide (ZnO), water (H2O), and potassium hydroxide (KOH) [[5]].

Fe(OH)2 ZnCl2 → Zn(OH)2 + FeCl2

The reaction between iron(II) hydroxide (Fe(OH)2) and zinc chloride (ZnCl2) produces zinc hydroxide (Zn(OH)2) and iron(II) chloride (FeCl2) [[6]].

Please note that these are the possible reactions based on the given reactants. The actual reaction that occurs may depend on various factors such as reaction conditions and concentrations of the reactants.
