1是什么?CcSO4...没这东西
(2)2NaCl=2Na+Cl2
(3)CuCL2=Cu+Cl2
(4)BaCL2=Ba+Cl2三个Cl2后面都有上箭头
2
(1)CuSO4+BaCl2=CuCl2+BaSO4↓,SO42-+Ba2+=BaSO4↓
(2)CuCl2+2AgNO3=2AgCl↓+Cu(NO3)2 ,Cl-+Ag+=AgCl↓
(3)NAOH+HCL=NACL+H20,OH-+H+=H20
(4)Ba(OH)2+2HCL=BaCL2+2H20,OH-+H+=H20
(5)Ba(OH)2+H2SO4==BaSO4↓+2H2O,Ba2++2OH-+H2SO4==BaSO4↓+2H2O
(6)H2SO4+Na2CO3==Na2SO4+CO2↑+H2O,2H++CO3 2-=CO2↑+H2O
(7)CaCO3+HCl=CaCl2+H2O+CO2↑,CO3 2-+2H+=H2O+CO2↑
(8)NaSO4+BaCL2=2NACI+BaSO4↓,SO42-+Ba2+=BaSO4↓
(9)CO2+2NAOH(过量)=NA2CO3+H2O ,CO2+2OH-=CO3 2-+H2O
(10)CH3COOH+NOH
(11)CuO+2HCL=CuCl2+H2O,CuO+2H+=Cu2+ +H2O
(12)Zn+CuSO4=ZnSO4+Cu ,Zn+Cu2+=Zn2++Cu
3.(1)CaCO3+2HCl=CO2↑+H2O +CaCl2
(2)CuCl2+2AgNO3=2AgCl↓+Cu(NO3)2
