Question

Hoàn thành các PTHH sau :

a/ Fe + O₂ \(\rightarrow\) Fe₃O₄

b/ AgNO₃ + ........ \(\rightarrow\) AgCl + Zn(NO₃)₂

c/ C₆H₆ + O₂ \(\rightarrow\) CO₂ + H₂O

d/ Fe_xO_y + H₂ \(\rightarrow\) Fe + H₂O

Answer 1

a, \(6Fe+2O_2\rightarrow2Fe_3O_4\)

b, \(2AgNO_3+ZnCl_2\rightarrow2AgCl+Zn\left(NO_3\right)_2\)

c, \(2C_6H_6+15O_2\rightarrow12CO_2+6H_2O\)

Answer 2

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

b) 2AgNO₃ + ZnCl₂ → 2AgCl↓ + Zn(NO₃)₂

c) C₆H₆ + \(\dfrac{15}{2}\)O₂ \(\underrightarrow{to}\) 6CO₂ + 3H₂O

d) Fe_xO_y + yH₂ → xFe + yH₂O

Answer 3

a/ 3Fe + 2O2 -> Fe3O4

b/ 2AgNO3 + ZnCl2 -> 2AgCl + Zn(NO3)2

c/ 2C6H6 + 15O2 -> 12CO2 + 6H2O

d/ FexOy + yH2 -> xFe + yH2O
