2. Guests come from
The guests came from there, but I left my spring guest beads.
There are words hidden in the beads, so you can't tell a book apart.
In order to meet the needs of the public, I kept silent for a long time.
Open your eyes and turn into blood, mourning for the absence of this sign.
Author: Tang Du Fu
Explanation:
(1) has a hidden word and a vague word. Because it is vague, I can't identify what a word, a book or an article is. Beads are made of tears, so I came up with the word "hidden" from the beads. After all, it is the word "tears". It is so vague, but it is so clear. It is intended to warn the ruling class to see clearly all the property they exploited, including the blood and tears of the people.
(2) seal and seal. Baskets, boxes for cultural relics. Wait, wait, wait Government, government, need, need, which is the so-called "levy".
Translation:
According to this poem, a guest from the south gave the poet a pearl with a pattern on it. The poet kept it in a box. After a long time, he opened the box and found it. The pearl disappeared, leaving only some red liquid.
Step 3 say goodbye
Affectionate is always ruthless, but you can't laugh until you feel it.
The candle on the table lit the heart, and it also saw the parting; You see, it shed tears for us and flowed to the morning.
Author: Tang Dumu
Explanation:
"Candle" has a wick, so it is said that "candle has a heart"; However, in the eyes of the poet, the wick became a "farewell" heart, symbolizing the candle. In the poet's eyes, the tears he overflowed all night were sad for the departure of the host and hostess. The words "shed tears for others until dawn" and "help others" make the meaning more profound. Until dawn also points out the length of the farewell banquet, which is also the performance of the poet's reluctance to go.
Translation:
Jiang Yan between Qi and Liang once summed up the feelings of parting as "forgetting me". But the expression of this kind of emotion varies from thing to thing and from person to person. This kind of emotion itself cannot be obtained by the words "sadness" and "sadness". Du Mu's poems did not use such words as "sadness" and "sorrow", but were written frankly and sincerely, telling the truth when leaving.

2. Five poems about chemistry cut out a deep mountain, and -CaCO3 decomposes.
When the fire started, it was idle. ——CaCO3====CaO
I'm not afraid of being smashed to pieces. -Cao+H2O = = Ca (OH) 2
Leave your innocence in the world. ——Ca(OH)2+CO2===CaCO3↓+H2O
Du Fu's guest followers:
The guests came from there, but I left my spring guest beads. There are words hidden in the beads, so you can't tell a book apart. In order to meet the needs of the public, I kept silent for a long time. Open your eyes and turn into blood, mourning for the absence of this sign.
According to this poem, a guest from the south gave the poet a pearl with a pattern on it. The poet kept it in a box. After a long time, he opened the box and found it. The pearl disappeared, leaving only some red liquid. Pearl is formed by agglutination of secretions produced by stimulation of the mantle of pearl oyster. Its main components are calcium carbonate and a small amount of inorganic substances. Du Fu's bedroom was wet by rain, and the bamboo box was wet, which reacted with water and carbon dioxide: CaCO3+H2O+CO2==Ca(HCO3)2, and became a red liquid.
Du Mu's farewell:
Affectionate is always ruthless, but you can't laugh until you feel it. The candle on the table lit the heart, and it also saw the parting; You see, it shed tears for us and flowed to the morning.
The composition of candles is paraffin wax, which belongs to solid hydrocarbons and has a low melting point. Can be burned in the air, and the reaction releases heat to melt the candle.

4. What's the story of classic organic chemistry? Once in class, she held a magnesium strip in one hand and an aluminum foil in the other, and said, "This is magnesium and this is aluminum, so together it is magnesium and aluminum." In the last two words, the boys in the class shouted together: beauty! )
1, calcium oxide and calcium hydroxide, they are birds of a feather. -What a shocking person!
2. When several reactions are carried out at the same time, the first is acid-base neutralization.
-Typical idiom misuse?
3. What is the first reaction when concentrated sulfuric acid splashes on the skin? -Scream, of course!
-Beverage ads?
An experiment was done next class today, which unexpectedly proved that human skin contains carbon.
(refers to the fingers accidentally burned black)
-A moment of silence for you?
5. Put zinc into the solution, which is called "rest assured"!
-So putting zinc in a jar is called "caring"?
6. Does zinc replace iron or copper first? Doesn't it pick soft bullying first? -Another shocking "Chemical Xiehouyu"
7. Are there two solutes in the solution? Are they two species?
-If your English is not good, please don't speak so interesting!
5. Write a poem containing chemical changes, and write that the chemical changes of Shenma are 1, and the mountains are cut out. If you accidentally set fire to it, innocence should stay on earth. CaCO3=CaO+CO2↑ (condition: high temperature) Cao+H2O = Ca (OH) 2ca (OH) 2+CO2 = CaCO3 ↓+. Every night, the candle will cry dry the wick. Melted wax oil (hydrocarbons and oxygen) burns to produce water and carbon dioxide. Wildfire never completely devoured them, and they grew taller again in the spring breeze. Combustion (combustion of macromolecular organic matter). Besides firecrackers, the spring breeze brought warmth to Tusu. 5. Explosions, gunpowder, and one hundred steelmaking are turned into finger bombs. 3co = Fe2O3 = high temperature = 2fe+3co2 = lead with bad color. Pb3o4+2c-→ 3pb+2co2 =, ancient alchemy. 7. Centennial wine and thyme. Ch3cooh+ch3ch3oh = ch3cooch3ch3h3+H2O (esterification reaction), and ethyl acetate is fragrant. Today, watching the wine-making King Ji of the Tang Dynasty tune the divine comedy in June, it is facing the beautiful spring ... several years have passed and there is no savings. C6H 12O6==2C2H5OH+2CO2, anaerobic respiration. 9. Nothing happened to Jude. The copper rusted. 2cu+O2+H2O+CO2 ═ ═ Cu2 (OH) 2co3。 Rot. 1 1, stop and sit in the maple forest late, the frost leaves are red in February. The increase of glucose and the low temperature in autumn are beneficial to the formation of anthocyanins. Therefore, the content of anthocyanin gradually increased and the content of chlorophyll gradually decreased. Anthocyanin is an unstable organic substance with no color. They turn red when they meet acidic substances and blue when they meet alkaline substances. In this way, anthocyanins turn blue in acidic mesophyll cells.
6. Five ancient poems or prose related to chemistry, please thank all the great gods. There are many ancient poems describing chemical properties, 1. Li Shangyin's Untitled: "When the spring silkworm dies, the wax torch starts to dry.
"There are both melting processes in physical changes and burning phenomena in chemical changes. The composition of candle is paraffin wax, which belongs to saturated hydrocarbon. Exothermic combustion in the air can melt solid paraffin into liquid wax tears. 2. Wang Anshi's "January Day": "After a year of explosion, the spring breeze warms Tu Su. "
This is a typical chemical change. Firecrackers are generally made of sulfur and other substances, which react chemically after being ignited to generate new substances such as sulfur dioxide. 3. Liu Kun's "Appreciating Lu Chen": "Why do you make a hundred steelmaking and turn it into a complex?" In fact, "making hundreds of steelmaking" is a process of continuously purifying pig iron.
4. Li Bai's Song of Autumn Pus: "Fire shines on heaven and earth, and red stars are purple." This poem also describes the scene of metal smelting at that time.
5. Yu Qian's Ode to Lime in the Ming Dynasty: "If a thousand hammers are dug out, if the fire burns, turn it off. I am not afraid of being smashed, I want to remain innocent in the world. "
It is not easy to mine limestone, which refers to physical changes. In this poem, "burning" refers to the chemical reaction of calcining limestone to produce calcium oxide and carbon dioxide. Coupled with the words "if leisure", people feel that this is not only burning limestone, but also symbolizes that people with lofty ideals are taking their time and treating it as leisure no matter how severe the test is. "Broken into pieces" embodies the changes of the body and expresses the spirit of not being afraid of sacrifice. Keeping the world innocent is the author's straightforward expression and his determination to be a pure and innocent person. Yu Qian's other object-chanting poem "Ode to Coal": "Digging chaos will bring black gold, and the most profound sun will be saved. Fire will revive spring, and the red furnace will break the night. Ding yiyuan is generated by strength, and the stone remains after death. I hope that the whole life is full of warmth and I will go out of the mountains tirelessly. " The author focuses on the formation, characteristics, properties and main uses of coal in the whole poem, and with the help of
The above is for reference.
