Question

Giúp mình hoàn thành chuỗi phản ứng sau ( ghi điều kiện nếu có)

Al→Al(NO3)3→Al(OH)3→ Al2O3→Al→Al4C3→CH4→ CO2→NaHCO3→Na2CO3→CO2→Ca(HCO3)2→CaCO3→CaCl2

Answer 1

Al+Fe(NO3)3=Fe(NO3)3+Fe

Al(NO3)3+3NH3+3H2O=Al(OH)3+3NH4NO3

2Al(OH)3=Al2O3+3H2O (nhiệt phân)

Al2O3=2Al+3/2O2 (điện phân nóng chảy, xúc tác 3NaF.AlF3 (criolit) )

4Al+3C=Al4C3 (nung)

Al4C3+12H2O=4Al(OH)3+3CH4

CH4+2O2=CO2+2H2O

CO2+NaOH=NaHCO3

NaHCO3+NaOH=Na2CO3+H2O

Na2CO3+2HCl=2NaCl+CO2+H2O

2CO2+Ca(OH)2=Ca(HCO3)2

Ca(HCO3)2+2NaOH=Na2CO3+CaCO3+2H2O

CaCO3+2HCl=CaCl2+H2O+CO2

Answer 2

Al+4HNO3->Al(NO3)3+NO+2H2O

Al(NO3)3+3NaOH->Al(OH)3+3NaNO3

2Al(OH)3->Al2O3+3H2O

2Al2O3->4Al+3O2

4Al+3C->Al4C3

Al4C3+12H2O->4Al(OH)3+3CH4

CH4+2O2->CO2+2H2O

CO2+NaOH->NaHCO3

NaHCO3+NaOH->Na2CO3+H2O

Na2CO3+2HCl->2NaCl+CO2+H2O

2CO2+Ca(OH)2->Ca(HCO3)2

Ca(HCO3)2+Ca(OH)2->2CaCO3+2H2O

CaCO3+2HCl->CaCl2+CO2+H2O

Answer 3

Al+4HNO3->Al(NO3)3+NO+2H2O

Al(NO3)3+3NaOH->Al(OH)3+3NaNO3

2Al(OH)3->Al2O3+3H2O

2Al2O3->4Al+3O2

4Al+3C->Al4C3

Al4C3+12H2O->4Al(OH)3+3CH4

CH4+2O2->CO2+2H2O

CO2+NaOH->NaHCO3

NaHCO3+NaOH->Na2CO3+H2O

Na2CO3+2HCl->2NaCl+CO2+H2O

2CO2+Ca(OH)2->Ca(HCO3)2

Ca(HCO3)2+Ca(OH)2->2CaCO3+2H2O

CaCO3+2HCl->CaCl2+CO2+H2O
