帮忙写几个化学方程式，然后改写为离子方程式，十分感谢！

氧化铁溶于盐酸 5.醋酸与氢氧化钙溶液反应 6.氧化铝溶于强酸溶液 3.碳酸钙与醋酸反应 21.锌与醋酸 4

Answer 1

.碳酸钙与醋酸反应
CaCO3+2CH3COOH==CO2↑+(CH3COO)2Ca+H20
CaCO3+2CH3COOH==CO2↑+2CH3COO-
+
Ca2+
+H20
2.氧化铝溶于强酸溶液
Al2O3+
6H+
==
2Al3+
+
3H2O
3.锌与醋酸
Zn+2CH3COOH==H2↑+(CH3COO)2Zn
Zn+2CH3COOH==H2↑+2CH3COO-
+Zn2+
4.氧化铁溶于盐酸
Fe2O3+6HCl
==
2FeCl3+
3H20
Fe203+6H+
==
2Fe3+
+
3H20
5.醋酸与氢氧化钙溶液反应
2CH3COOH+Ca(OH)2
==2H20+(CH3COO)2Ca
CH3COOH
+
OH-==
H2O
+
CH3COO-
6.醋酸与氨水反应
CH3COOH+NH3·H20
==
CH3COONH4+
H20
CH3COOH+NH3·H20
==
CH3COO-
+
NH4+
+H20

Answer 2

Ca
CO3
+
2CH
3COOH=(CH3COO)2Ca+H2O+CO2
CO3(2-)+2
CH3COOH
=H2O+CO2+2CH3COO（-）
Al2O3
+6HCl=3H2O+2
AlCl3
Al2O3+6H(+)=3H2O+2Al(3+)
Zn+2CH3COOH=(CH3COO)2Zn+H2
Zn+2CH3COOH=Zn(2+)+H2+2CH3COO（-）
Fe2O3
+6HCl=2
FeCl3
+3H2O
Fe2O3+6H(+)=2Fe(3+)+3H2O
CH3COOH+NaOH=CH3COONa+H2O
CH3COOH+OH(-)=CH3COO(-)+H2O
CH3COOH为
弱电解质
CH3COOH+NH3.H2O=
CH3COONH4
+H2O
