Question

Hoàn thành các PTHH sau :

a/ Fe + O₂ \(--\rightarrow\) Fe₃O₄

b/ Al₂O₃ + HCl \(--\rightarrow\) AlCl₃ + H₂O

c/ C₃H₆ + O₂ \(--\rightarrow\) CO₂ + H₂O

d/ Fe₂O_n + HCl \(--\rightarrow\) FeCl_n + H₂O

Answer 1

a) 3Fe + 2O₂ \(\underrightarrow{to}\) Fe₃O₄

b) Al₂O₃ + 6HCl → 2AlCl₃ + 3H₂O

c) C₃H₆ + \(\dfrac{9}{2}\)O₂ \(\underrightarrow{to}\) 3CO₂ + 3H₂O

d) Fe₂O_n + 2nHCl → 2FeCl_n + nH₂O
