My best friend in high school is Lan. Lan sits next to me in class, eats with me at break time, and hangs out with me after school. She has long and beautiful hair; my mother always says that I need to pay more attention to my hair so it can be pretty as hers. I am good at English while Lan is excellent in Math, therefore we can help each other every time one of us has trouble in understanding those subjects. Besides our study, Lan is always by my side whenever I feel upset. I tell her everything, and only her can know my true feelings. We have been best friends since our young age, and I will keep this friendship forever.

Dịch:
Bạn thân nhất ở trường của tôi là Lan. Lan ngồi cạnh tôi trong lớp, ăn cùng tôi vào giờ giải lao, và cùng đi chơi với tôi sau giờ tan trường. Cô ấy có mái tóc dài và đẹp, mẹ tôi luôn bảo rằng tôi cần chú ý đến mái tóc của tôi nhiều hơn để nó có thể được đẹp như tóc Lan. Tôi giỏi tiếng Anh còn Lan giỏi Toán, vậy nên chúng tôi có thể giúp đỡ lẫn nhau mỗi khi một trong hai chúng tôi gặp rắc rối trong những môn đó. Bên cạnh việc học, Lan luôn bên cạnh tôi mỗi khi tôi buồn. Tôi kể Lan nghe nghe mọi thứ, và chỉ có Lan biết được cảm giác thật sự của tôi. Chúng tôi đã là bạn kể từ khi cả hai còn nhỏ, và tôi sẽ giữ tình bạn này mãi mãi.

(oh) hóa trị 1 mà zn hóa trị 2=> cthh la zn(oh)2

với lại ko có oh2 dau chi co OH hoac la H2O

phải viết là Zn(OH)₂ vì nhóm (OH) hóa trị I

Nhưng mà Zn có hóa trị là II, nhóm (OH2) có hóa trị là I, nếu như vậy, theo CTHH, ta có:

\(x.II=y.I\Rightarrow\frac{X}{Y}=\frac{I}{II}\Rightarrow X=1;Y=2.\)

Vậy CTHH của hợp chất là: Zn(OH₂)₂ chứ nguyên nhóm (OH₂ ) có hóa trị là I mà chứ đâu phải nhóm (OH). Xem lại giùm mình đi bạn!
