Chia nhỏ bài ra nhé em!

Bạn xem lại cho mình PTPU số 7

a) K₂O  +  H₂O  →  2KOH (phản ứng hóa hợp).

b)  2Al(OH)₃     \(\underrightarrow{t^o}\)    Al₂O₃   +   3H₂O (phản ứng phân hủy)

c) Fe₂O₃  +  3H₂  \(\underrightarrow{t^o}\)  2Fe  +  3H₂O ( phản ứng oxi hóa khử)

d) Zn  + CuSO₄  →  ZnSO₄  +  Cu  (phản ứng thế)

Em xem lại các bài học sau để nắm rõ định nghĩa về các loại phản ứng nhé
