Answer 1

1.Fe2O3+3CO- > 2Fe + 3CO2

2.3AgNO3+Al -> Al(NO3)3+ 3Ag

3.2HCl+CaCO3 -> CaCl2+H2O+ CO2

4.2C4H10+5O2 -> 4CO2+2H2O

5.NaOH+FE2(SO4)3 -> Fe(OH)3+Na2SO4

6.4FeS2+11O2 -> 2Fe2O3+8SO2

7.6KOH+Al2(SO4)3 -> 3K2SO4+2Al(OH)3

9.8Al+3Fe3O4 -> 4Al2O3+9Fe

10.Fe3O4+4CO -> 3Fe+4CO2

11.FeO+H2 -> Fe+H2O

11.FeO+H2 -> Fe+H2O

Answer 2

PTHH 1: Fe₂O₃ + 3CO -t^o-> 2Fe + 3CO₂

PTHH 2: 3AgNO₃ + Al -> Al(NO₃)₃ + 3Ag

PTHH 3: 2HCl + CaCO₃ -> H₂O + CO₂ + CaCl₂

PTHH 4: 2C₄H₁₀ + 13O₂ -> 8CO₂ + 10H₂O

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

PTHH 6: 4FeS₂ + 11O₂ -t^o-> 2Fe₂O₃ + 8SO₂

Answer 3

3CO + Fe2O3 → 2Fe +
3CO2

3AgNO3 + Al → 3Ag +
Al(NO3)3

CaCO3 + 2HCl → H2O + CO2 + CaCl2

13O2 + 2C4H10 → 10H2O +
8CO2

Fe2(SO4)3 + 6NaOH → 3Na2SO4 + 2Fe(OH)3

4FeS2 + 11O2 → 2Fe2O3 + 8SO2

Al2(SO4)3 + 6KOH → 2Al(OH)3 + 3K2SO4

12CH4 + 5H2O + 5O2 → 9CO + 29H2 + 3CO2

8Al + 3Fe3O4 → 4Al2O3 + 9Fe

CO+Fe3O4→3FeO+CO2

FeO + H2 → Fe + H2O

Answer 4

PTHH 7: 6KOH + Al₂(SO₄)₃ -> 2Al(OH)₃ + 3K₂SO₄

PTHH 8: CH₄ + \(\frac{3}{2}\)O₂ + H₂O -> CO₂ + 2H₂

PTHH 9: 8Al + 3Fe₃O₄ -t^o-> 4Al₂O₃ + 9Fe

PTHH 10 bạn cho đề sai mình làm lại đề nha:

Fe_xO_y + yCO -t^o> xFe + yCO₂

PTHH 11: FeO + H₂ -t^o-> Fe + H₂O
