Giúp e vs, sáng mai lấy gấp nha a chị

Answer 1

a, 1, S + O2 \(\underrightarrow{t^o}\) SO2

2, 2SO2 + O2 \(\xrightarrow[V2O5]{t^o}\) 2SO3

3, SO3 + H2O -----> H2SO4

4, H2SO4 + 2NaOH ----> Na2SO4 + 2H2O

5, Na2SO4 + BaCl2 ---> BaSO4 + 2NaCl

b, 1: CaCO3 \(\underrightarrow{t^o}\) CaO + CO2

2, CaO + H2O ---> Ca(OH)2

3, Ca(OH)2 + Mg(NO3)2 ---> Ca(NO3)2 + Mg(OH)2

c, 1, 2Cu + O2 \(\underrightarrow{t^o}\) 2CuO

2, CuO + 2HCl ----> CuCl2 ++ H2O

3, CuCl2 + 2NaOH ---> 2NaCl + Cu(OH)2

4, Cu(OH)2 + 2HNO3 ---> Cu(NO3)2 + 2H2O

d, 1, 2Fe + 3Cl2 \(\underrightarrow{t^o}\) 2FeCl3

2, FeCl3 + 3NaOH ----> 3NaCl + Fe(OH)3

3, 2Fe(OH)3 \(\underrightarrow{t^o}\) Fe2O3 + 3H2O

4, Fe2O3 + 3H2SO4 ---> Fe2(SO4)3 + 3H2O

5, Fe2(SO4)3 + 6NaOH---> 3Na2SO4 + 2Fe(OH)3

e, 1, 4Al + 3O2 \(\underrightarrow{t^o}\) 2Al2O3

2, Al2O3 + 6HCl ----> 2AlCl3 + 3H2O

3, AlCl3 + 3NaOH ---> 3NaCl + Al(OH)3

4, 2Al(OH)3 \(\underrightarrow{t^o}\) Al2O3 + 3H2O

5, 2Al2O3 \(\xrightarrow[criolit]{t^o}\) 4Al + 3O2

6, 2Al + 6HCl ---> 2AlCl3 + 3H2
