Question

Hoàn thành các PTHH sau:

a/ Al + O₂ \(\rightarrow\) Al₂O₃

b/ Fe₂O₃ + ...... \(\rightarrow\) FeCl₃ + H₂O

c/ C₅H₁₀ + O₂ \(\rightarrow\) CO₂ + H₂O

d/ Fe₃O₄ + CO \(\rightarrow\) Fe + CO₂

Answer 1

a)4Al+3O₂→2Al₂O₃

b) Fe₂O₃+6HCl→2FeCl₃+3H₂O

c) 2C₅H₁₀+15O₂→10CO₂+10H₂O

d) Fe₃O₄+4CO→3Fe+4CO₂

Answer 2

a) 4Al + 3O₂ \(\underrightarrow{to}\) 2Al₂O₃

b) Fe₂O₃ + 6HCl → 2FeCl₃ + 3H₂O

c) C₅H₁₀ + \(\dfrac{15}{2}\)O₂ \(\underrightarrow{to}\) 5CO₂ + 5H₂O

d) Fe₃O₄ + 4CO \(\underrightarrow{to}\) 3Fe + 4CO₂

Answer 3

Hoàn thành các PTHH sau:

a/ 2Al + \(\dfrac{3}{2}\)O₂ → Al₂O₃
