判断下列复分解反应能否发生,能则写出化学方程式
(1)KCl + AgNO3 --- (2)H2SO4 + NaOH --- (3)NaNO3 + KCl ---
(4)Na2CO3 + KOH --- (5)Fe(NO3)3 + CuSO4 --- (6)Na2CO3 + Ba(OH)2 ---
(7)Cu + ZnSO4 --- (8)CaCO3 + HNO3 --- (9)ZnSO4 + (NH4)2CO3 ---

(1)1)KCl + AgNO3 =AgCl↓+KNO3 (2)H2SO4 + 2NaOH =Na2SO4+2H2O (6) Na2CO3 + Ba(OH)2=BaCO3↓+2NaOH (8)CaCO3 + 2HNO3=Ca(NO3)2+CO2↑+H2O (9)ZnSO4 + (NH4)2CO3=ZnCO3↓+(NH4)2SO4 (3)(4)(5)(7)不反...
