So sánh ngũ ngôn cổ thể với ngũ ngôn hiện đại giúp mình với

`(1)FeO + H_2SO_4 -> FeSO_4 + H_2O`

`(2)FeSO_4 + Ba(OH)_2 -> Fe(OH)_2 + BaSO_4`

`(3)Fe(OH)_2 -> (t^o, chân.không) FeO + H_2O`

`(4)FeO + 2HCl -> FeCl_2 + H_2O`

\(\left(1\right)CuO+H_2SO_4\rightarrow CuSO_4+H_2O\\ \left(2\right)CuSO_4+BaCl_2\rightarrow BaSO_4\downarrow\left(trắng\right)+CuCl_2\\ \left(3\right)CuCl_2+2KOH\rightarrow Cu\left(OH\right)_2\downarrow\left(xanh.lam\right)+2KCl\)

\(\left(1\right)2Fe+3Cl_2\xrightarrow[t^0]{}2FeCl_3\\ \left(2\right)FeCl_2+3NaOH\rightarrow Fe\left(OH\right)_3+3NaCl\\ \left(3\right)2Fe\left(OH\right)_3\xrightarrow[t^0]{}Fe_2O_3+3H_2O\\ \left(4\right)Fe_2O_3+3H_2SO_4\rightarrow Fe_2\left(SO_4\right)_3+3H_2O\)

\((1) CaC_2 + 2H_2O \to Ca(OH)_2 + C_2H_2\\ (2) C_2H_2 + H_2 \xrightarrow{t^o,PbCO_3} C_2H_4\\ (3) C_2H_4 + H_2O \xrightarrow{t^o,H^+} C_2H_5OH\\ (4) C_2H_5OH + O_2 \xrightarrow{men\ giấm} CH_3COOH + H_2O\\ (5) CH_3COOH + C_2H_5OH \buildrel{{H_2SO_4}}\over\rightleftharpoons CH_3COOC_2H_5 + H_2O\)

1) Na₂O + H₂O \(\rightarrow\)2NaOH

2) 2NaOH+ SO₂ \(\rightarrow\)Na₂SO₃ + H₂O

3) Na₂SO₃ + H₂SO_{4\(\rightarrow\)} Na₂SO₄ + H₂O+ CO₂

4)SO₂ + 2KOH \(\rightarrow\)K₂SO₃ + H₂O

1.Na2O+H2O--->2NaOH

2.2NaOH+SO2--->Na2SO3+H2O

3.Na2SO3+H2SO4--->Na2SO4+H2O+CO2

4.2KOH+SO2--->K2SO3+H2O

(1) S+02===> S02 ( Nhiệt độ)

(2) 2SO2+ 02===> 2S03( ĐIỀU KIỆN V2O5, 450 độ)

(3) S03+ H20=====> H2S04

(4)3 H2S04+ 2Al====> Al2( S04)3+ 3/2H2 

(5) ZnO+ H2===> Zn+ H20

(6) Zn+ HCl=====> ZnCl2+ H2
