Mình thích môn Thể Dục cơ =)) Nhưng cứ viết cho bạn về môn Tiếng Anh 

 My favorite subject is English. The first reason I like this subject is that itis a core subject which is vital and essential in my career path. I try to learn thisinternational language well so that I can communicate with foreigners and find agood job in the future. Furthermore, learning English well can help me readbooks or magazines in English. Through reading things in English, I can beexposed to various cultures and customs. Besides, my English teacher is adedicated person who can engage me in her lessons and bring the passion for me.I found her lessons interesting because she delivered them in a way that I reallyliked. In short, English is an important subject which I am really keen on.

1. What subject
2. What it deals with
3. Why I like it
4. The end

I learn many subjects in school. But the one I enjoy learning is History.

History helps us know what people did and how they lived ages ago. It also tells us how men had to manage to make their lives better and better.

Many learners, however, do not like to read History. They say that there are too many names and dates to remember. But they do not understand that if we know nothing about the past, we cannot have a good knowledge of the present. For example, if we wish to know how men learnt to use fire or clothes, we have to know what men did in the past to travel at night or to keep themselves warm. In fact, only a study of History will make us realize that what we do today is the result of what our ancestors did in the past. History therefore is a long story of man’s struggle through the ages. As we read the story, we are learning many interesting things.

I enjoy learning history. I have a large number of history books in my house. Some day, I might even write a history book myself.

Thanks 

câu chuyện nào

I don"know.

Cuộc chia tay của những con búp bê phải ko bạn

dc = bc , 2 góc này kề bù nhau 

=) a // b 

vì a kề bù với x nên 

ta có : a + x = 180 độ 

=) 75 độ + x = 180 độ

=) x = 105 

vậy x = 105 độ

Đề sai nha

Bài 3: 

PTHH: \(2R+O_2\xrightarrow[]{t^O}2RO\)

Theo PTHH: \(n_R=n_{RO}\) \(\Rightarrow\dfrac{3,6}{M_R}=\dfrac{6}{M_R+16}\)

  \(\Rightarrow M_R=24\)  (Magie)

Bài 4 ở đâu vậy ??

Bài 2: 

 PTHH: \(2Al+6HCl\rightarrow2AlCl_3+3H_2\uparrow\)

Ta có: \(n_{Al}=\dfrac{8,1}{27}=0,3\left(mol\right)\)

\(\Rightarrow\left\{{}\begin{matrix}n_{HCl}=0,9\left(mol\right)\\n_{AlCl_3}=0,3\left(mol\right)\\n_{H_2}=0,45\left(mol\right)\end{matrix}\right.\) \(\Rightarrow\left\{{}\begin{matrix}V_{H_2}=0,45\cdot22,4=10,08\left(l\right)\\m_{AlCl_3}=0,3\cdot133,5=40,05\left(g\right)\\m_{ddHCl}=\dfrac{0,9\cdot36,5}{7,3\%}=450\left(g\right)\\m_{H_2}=0,45\cdot2=0,9\left(g\right)\end{matrix}\right.\)

Mặt khác: \(m_{dd\left(saup/ứ\right)}=m_{Al}+m_{ddHCl}-m_{H_2}=457,2\left(g\right)\)

\(\Rightarrow C\%_{AlCl_3}=\dfrac{40,05}{457,2}\cdot100\%\approx8,76\%\) 

đa thức trên không có nghiệm vì

với mọi x=a ( dương) thì 2a^4+3a+1 luôn luôn > 0

Mk lấy bài này trên tiếng anh 123 , link là : www.tienganh123.com

Three people were asked about their hometowns and here is what they said.

Lam: Welcome to Ha Long Bay! Ha Long Bay belongs to Ha Long city in Quang Ninh province.It is famous for natural beauties with many islands and caves. There are many large hotels and beautiful beaches here. Besides, the air is very fresh and cool. The seafood here is more delicious and cheaper than the seafood in Hanoi. Now there are big supermarkets and amusement parks, which makes life here even more fun.

Mai: My hometown is Sa Pa which is a peaceful town in Lao Cai province. Sa Pa has beautiful mountains and hills and the weather is pleasant, especially there are four seasons on a summer day here. One more thing, you can find Fansipan, the highest peak of Vietnam, in my hometown.All of these attract many tourists both in Vietnam and from abroad to come here and enjoy their holidays.

Hoa: My family and I live in Ho Chi Minh City. It is a very big city, even bigger than Hanoi. There are many high office buildings, shopping centers, and restaurants in my neighbourhood. What I really like here is the weather. There is no winter and the sun shines every day. People from all around the country come here to live, study, and work. So it is good because you can learn about different cultures. But sometimes it is just too noisy.
