\(n_{C_3H_7NO_2}=\dfrac{22,25}{89}=0,25mol\)

=> \(n_{HCl}=0,25mol\)

Ta có:

\(m_M=m_{Alanin}+m_{HCl}=22,25+0,25.36,5=31,375g\)

\(n_{N_2}=\dfrac{0,56}{22,4}=0,025mol\)

\(\Rightarrow m_{N_2}=0,025.28=0,7g\)

\(n_{H_2}=\dfrac{3,36}{22,4}=0,15mol\)

Gọi M là công thức chung của 2 KL:

\(M+2HCl\rightarrow MCl_2+H_2\)

\(\Rightarrow n_M=0,15mol\)

\(\Rightarrow\overline{M}=\dfrac{4,4}{0,15}=29,33\)

=> Hai kiêm loại đó là Mg và Ca

\(N_{H_2}=\dfrac{6,72}{22,4}=0,3mol\)

\(R+H_2SO_4\rightarrow RSO_4+H_2\)

Bảo toàn e ta có:

\(\dfrac{7,2}{M_R}.n=0,3.2=0,6\)

\(\Rightarrow7,2n=0,6.M_R\Leftrightarrow12n=M_R\)

Nếu n =1 => M = 12 ( loại)

Nếu n = 2 => M = 24 (Mg)

Read the passage carefully and choose the correct answer.

REMEMBER?

Your mind's ability to bring back experiences you have had is your memory. There are two kinds of remembering, recall and recognition. For instance, you may not be able to recall the poem you read yesterday in class, but if you see it again, you will know it instantly because you recognize it.

Some few people have 'total recall,' often spoken of as photographic memory. A person with total recall can recite a whole page of a book he has read only once, or playa musical composition after hearing it once. This is very unusual, however, and most people have difficulty in remembering even names they heard the day before. This is not because most people lack the ability to remember, but because they had not paid much attention to what they heard. They felt no personal reasons to remember. Having a personal reason for remembering is one of the most important factors in a good memory.

When you have a strong reason for remembering, concentrate as you read or listen, and try to connect the new information to things you I already know. A detail is easy to remember when it fits into a whole that makes sense. If you understand the entire history lesson before you try to remember any particular dates, your memory may surprise you.

43. A person with photographic memory is ________.

a. can only remember things if he looks at a photograph

b. can remember every detail of what he sees or hears

c. can be found in mental hospitals

d. brings his camera everywhere he goes

44. One way to improve our memory is ________

a. to ask other people to repeat something you want to remember.

b. to have a camera with you all the time

c. to concentrate on what you hear or read

d. to learn everything by heart

45. Which sentence is not true?

\(n_{CO_2}=\dfrac{5,04}{22,4}=0,225mol\)   =>  \(n_C=0,225mol\)

\(\Rightarrow m_C=0,225.12=2,7g\)

\(n_{H_2O}=\dfrac{4,05}{18}=0,225mol\)

\(\Rightarrow m_H=0,225.2=0,45g\)

\(\Rightarrow m_O=5,55-2,7-0,45=2,4g\)

\(\Rightarrow n_O=\dfrac{2,4}{16}=0,15mol\)

\(x:y:z=0,225:0,45:0,15\)

              \(=\dfrac{3}{2}:3:1=3:6:2\)

\(n_{H_2}=\dfrac{12,32}{22,4}=0,55mol\)

\(Fe+2HCl\rightarrow FeCl_2+H_2\)
