The last question: Reflections after class... Urgent!!!!

Xianglin's sister-in-law has a sense of resistance, and has a strong sense of resistance. Our reasons are as follows: 1. Xianglin's sister-in-law fled overnight because she was dissatisfied with her mother-in-law's desire to sell herself; Second, Xianglin's sister-in-law was so out of line when she was forced to remarry that she hit her head on the incense case; 3. In order to pursue the status of "people", Xianglin's sister-in-law did not hesitate to donate the threshold with the accumulated wages of the year; Fourth, after suffering a series of heavy blows, Xianglin's sister-in-law asked "me" about the existence of the soul, indicating that she had doubts about feudal superstition.

Based on the above, we believe that Xianglin's sister-in-law is rebellious, and has a strong sense of resistance. (let's draw it in a book according to the contents).

Why did Xianglin's sister-in-law fight?

The reason for her struggle is actually the deep-rooted patriarchal idea of "women from the beginning to the end" in her mind. For thousands of years, China's feudal society has imprisoned women's thoughts, especially for their chastity, and has formulated countless rules and precepts: "starvation to death is a small matter, loss of temperament is a big matter", "a good woman does not marry a second husband" and so on, like a shackle as tightly as a long-term constraint on women's thoughts.

Since it is "from the beginning to the end", then remarriage naturally violates the norm and is not done by a chaste woman. For Xianglin's sister-in-law, her resistance to remarriage is actually to be a virgin, although it is not out of instinct to protect her will. However, her struggle maintained feudal etiquette, and she was powerless to break through the strong feudal etiquette and heavy shackles and could only become its victim, which finally made Xianglin's rebellion tragic.

What is the essence of this struggle?

Can she change her tragic fate?

We can see that Xianglin's sister-in-law has resisted three times in her life, but the end of the rebellion has ended in failure. She is unlucky, and the root cause of this unfortunate tragedy is precisely the feudal ideology of etiquette that has ruled China for thousands of years, so the tragedy of Xianglin's rebellion has a deeper and broader social connotation and value.

The second question plays the role of echoing before and after

She worked hard to save money, and begged many times to donate money to the temple and donate a threshold. She hopes to atone for her sins through the stand-in of the threshold, and hopes that she will not be tortured by her two husbands in hell. After donating the threshold, she was in a good mood for a long time, but this external sustenance did not last long, and was broken when she was preparing for the sacrifice during the New Year.

You don't see the water of the Yellow River coming up from the sky, rushing to the sea and not returning (Li Bai will enter the wine).

If you don't reach the Yellow River, you won't die] is a metaphor for not stopping and losing the chain if you don't reach your goal. It is also more than Ran Cong, who can't describe the situation of Chaduansun, who really has no way out, and refuses to give up.

If NH4HCO3 is 1mol, it will be decomposed to generate 1molNH molh2O and 1molCO2.

If Na2O2, H2O, and CO2 participate in the reaction first, Na2O2 increases by 30g, A=30, and then is absorbed by concentrated H2SO4 and NH3, and concentrated H2SO4 increases by 17g, B=17

If it is absorbed by concentrated H2SO4, NH3 and H2O first, the concentrated H2SO4 increases by 35g, c=35After participating in the reaction by Na2O2 and CO2, Na2O2 increased by 28g, d=28. Therefore, it is CADB, choose A

1molH2O reacts with Na2O2 to change 1molNa2O2 to 2molNaOH and increase by 2 g.

1molCO2 reacts with Na2O2 to change 1molNa2O2 to 1molNa2CO3, an increase of 28 g.

It is assumed that NH4HCO3 has 2mol

NH4HCO3 = Heating = NH3 + H2O + CO22mol 2mol 2mol 2mol

1. Pass a sufficient amount of Na2O2 first

2na2o2 + 2co2 = 2na2co3 + o22mol 2mol 2mol 1mol

Solid weight gain = 2mol x 106g mol - 2mol x 78g mol = 56g

2na2o2 + 2h2o = 4naoh + o22mol 2mol 4mol 1mol

Solid weight gain = 4mol x 40g mol-2mol x 78g mol = 4g so a = 56g + 4g = 60g

After concentrated sulfuric acid, 2NH3 +H2SO4 = (NH4)2SO4 is obviously absorbed by 2molNH3.

Therefore b = 2 mol x 17 g mol = 34 g

2. First through concentrated sulfuric acid, 2NH3 +H2SO4=(NH4)2SO4 Obviously, 2molNH3 is all absorbed, and 2molH2O is also absorbed.

So c = 2mol x 17g mol + 2mol x 18g mol = 70g

Then pass a sufficient amount of Na2O2

2na2o2 + 2co2 = 2na2co3 + o22mol 2mol 2mol 1mol

Solid weight gain = 2mol x 106g mol - 2mol x 78g mol = 56g

Therefore d = 56g + 4g = 60g

To sum up: a=60g b=34g c=70g d=56g, then there is: c>a>d> b

From the meaning of the title: set: cloth is long x meters.

then x-14=2(x-25).

x-14=2x-50

x=-36x=36

(25-14) (2-l) 2-11

25 x11 ii 36

It turns out that both blocks are 36 meters each.

After using the total number of hectares to remove the total number of hectares and the corresponding time, the average hectares per hour of each brother are calculated, and then the total number of hectares per hour is removed by the rice transplanter, and then the total number of hectares per hour is removed.

The rice transplanter is approximately equal to the artificial equal.
