1. What are the poems about chemistry?

1. Lime Ode

Thousands of hammers carved out the deep mountains, and the fire burned them as if nothing happened.

Don’t be afraid of being shattered into pieces, you must remain innocent in this world.

Author: Ming Yu Qian

Explanation:

(1) Lime chant: Praise for lime. Yin: chant. Refers to the name of an ancient poetry genre {a form in ancient times}

(2) Thousands of hammers and thousands of chisels: Countless hammerings and excavations describe the difficulty of mining lime. Thousands, ten thousand: refers to the number of impacts, not eleven thousand. Hammer: to hammer. Chisel: to dig.

(3) If it is easy: it seems to be a common thing. If: as if, as if; leisurely: ordinary, relaxed.

(4) Innocence: refers to the pure white nature of lime, and also metaphors noble moral integrity. Human world: human world.

Translation:

Stones can only be mined from the mountains after repeated impacts. They regard burning by fire as a normal thing. They are not afraid even if their bodies are broken into pieces, and they are willing to sacrifice their innocence. Stay in the world.

2. The guest came from

The guest came from Nanming, leaving behind my spring guest pearl.

There are hidden characters in the beads, which cannot be written down if I try to identify them.

The seal should be sealed for a long time in case the official needs it.

The sight turns into blood, and the sorrow is gone.

Author: Tang Du Fu

Explanation:

(1) There is a hidden word, a vague word. Because it was vague, I couldn't tell what the word was. "Book" means writing. Beads are made of teardrops, so we came up with the word "hidden" from the beads. This word is literally the word "tears". It's so blurry, yet so clear. It is intended to warn the ruling class that they should see that all the property they exploit contains the blood and tears of the people.

(2) Silence, seal. A box, a box for hiding things. Wait. The public family, the official family, must, need, that is, the so-called "collection".

Translation:

The poem says that a guest from the south gave the poet a pearl. There seemed to be patterned writing on the pearl. The poet kept it in a box. After a long time , opened the box and looked, the pearls were gone, leaving only some red liquid.

3. Farewell

Passionate but always ruthless, I can’t laugh in front of the bottle.

The candle bids farewell with intention and sheds tears for others until dawn.

Author: Tang Du Mu

Explanation:

"Candles" originally have wicks, so it is said that "candles have hearts"; but in the eyes of the poet The candle wick has become a feeling of "farewell", personifying the candle. In the eyes of the poet, the candle tears that overflowed all night long were sad for the separation of the host and hostess. "Weep for others until dawn", the word "for others" makes the meaning deeper. "Until dawn" also points out the long time for farewell banquet, which is also a manifestation of the poet's unbearable separation.

Translation:

Jiang Yan between Qi and Liang once summed up the feelings of parting as "sadly ecstatic". However, the expression of this kind of emotion varies greatly from person to person and from different situations. This kind of emotion itself cannot be described by the words "sadness" and "sorrow". Du Mu does not use the words "sadness" and "sadness" in this poem, but it is written frankly and sincerely, expressing his true feelings when parting.

4. Yuan's Day

The sound of firecrackers marks the end of the year, and the spring breeze brings warmth to Tusu.

Thousands of households always exchange old talismans for new peaches.

Author: Wang Anshi of Song Dynasty

Translation:

With the sound of crackling firecrackers, we bid farewell to the old year and welcome the new year. People welcomed the warm spring breeze and drank the delicious Tusu wine happily. Every household is illuminated by the rays of the sun, and every household takes down the old Spring Festival couplets and replaces them with new ones during the New Year.

Explanation:

(1) Firecrackers: the popping sound made when ancient people burned bamboo. It was used to ward off ghosts and evil spirits, and later evolved into setting off firecrackers (firecrackers).

(2) Tusu: the name of medicinal wine. It is an ancient custom for the whole family to drink this kind of wine soaked in Tusu grass on the first day of the Lunar New Year to ward off evil spirits, avoid plague, and seek longevity.

(3)曈曈: The bright and warm appearance at sunrise.

(4) Peach: Peach charm is an ancient custom. On the first day of the first lunar month, people write the names of the two gods Shen Tu and Yu Lei on peach boards and hang them by the door to suppress evil spirits. Also used as Spring Festival couplets.

(5) Thousands of Houses: Describes a large house or a large number of households.

5. Miscellaneous Poems of Ji Hai·Part 5

The sun is setting in the day when I am about to leave, and I sing my whip to the east and point to the end of the world.

Falling red is not a heartless thing, it turns into spring mud to protect flowers.

Author: Qing Gong Zizhen

Translation:

The vast sadness of farewell extends to the distance where the sunset sets to the west, leaving Beijing and heading eastward. Wai, it feels like you are at the end of the world.

When I resign and return home, I am like a fallen flower falling from a branch, but it is not a heartless thing. It turns into the soil of spring and can also play a role in nurturing the next generation.

Explanation:

(1) Vast sorrow: The sorrow of leaving Kyoto is as vast as water waves, which also refers to the author's upset mood. Vast: Infinite.

(2) Yin whip: the poet's riding whip. East refers to: the hometown of the East. Tianya: means far away from Kyoto.

(3) Luohong: Falling flowers. Flowers that are red are considered noble, so fallen flowers are also called fallen flowers.

(4) Flower: a metaphor for the country. That is: arrive. 2. Five poems about chemistry

Thousands of hammers are used to carve out the mountains, - CaCO3 decomposes

The fire burns as if it were nothing. ——CaCO3====CaO

Don’t be afraid of being shattered into pieces, ——CaO+H2O===Ca(OH)2

You must remain innocent in the world. ——Ca(OH)2+CO2===CaCO3↓+H2O

Du Fu’s guests came from:

The guests came from Nanming, leaving me the spring guest pearl. There are hidden words in the beads, and I cannot write them down if I try to identify them. Keep the case sealed for a long time, in case the official needs it. The sight turns into blood, and the sorrow is gone.

The poem says that a guest from the south gave the poet a pearl. There seemed to be patterned writing on the pearl. The poet kept it in a box. After a long time, he opened the box and looked for it. The pearl was missing. And Fei, only some red liquid is left. Pearls are formed by the agglomeration of secretions produced after the mantle of pearl oysters is stimulated. Its main component is calcium carbonate and a small amount of inorganic substances. Du Fu's room was leaking and damp, and when the bamboo box encountered moisture, it reacted with water and carbon dioxide: CaCO3+H2O+CO2==Ca(HCO3)2, turning into a red liquid

Du Mu's farewell:

Passionate but always ruthless, I can't laugh in front of the bottle. The candle bids farewell with intention and sheds tears until dawn.

The component of candles is paraffin, which is a solid hydrocarbon with a very low melting point and can burn in the air. The reaction releases heat and melts the candle. 3. Chemistry-related verses

Oh, let’s make waves for the ship of mankind (Ending: Make waves with all our strength) 4. What are the jokes about classic organic chemistry

By the way, there are During a class, (probably to introduce metals), she held a magnesium strip in one hand and an aluminum foil in the other, and said: "This is magnesium, this is aluminum, then together they are - magnesium aluminum." (The last two are magnesium. When writing, all the boys in the class shouted: Beauty! )

1. Calcium oxide and calcium hydroxide are the same. ——How shocking!

2. When several reactions are carried out at the same time, the first one to bear the brunt is acid-base neutralization.

——Typical idiom misuse Ing?

3. When concentrated sulfuric acid splashes on the skin, what is the first reaction? ——Screaming of course!

——Drink advertisement?

4. I was doing an experiment in the next class today and accidentally proved that human skin contains carbon.

(Referring to his finger being accidentally burned and turning black)

——A moment of silence for you?

5. Put zinc into the solution. This is called "rest assured"!

——So is putting zinc in a jar called "care"?

6. Does zinc replace iron or copper first? Doesn’t it pick out the soft ones first and bully them? ——Another shocking "chemistry saying"

7. Are there two solutes in the solution? Are they two species?

——Please, don’t speak so funny even if your English is not good! 5. Write a poem that contains chemical changes, write what is the chemical change of Shenma

1. Thousands of blows will chisel out the mountains, and the fire will burn them as if it were nothing. The body will be shattered into pieces, but the innocence will remain in the world.CaCO3 =CaO+CO2↑ (Condition: high temperature) CaO+H2O= Ca(OH)2Ca(OH)2+ CO2= CaCO3↓+H2O2. The spring silkworms will not run out until the silkworms die, and the wax torch will turn into ashes and tears before drying. Melted wax oil (Hydrocarbons and oxygen) burn to produce water and carbon dioxide. 3. The wildfire cannot be burned out, and the spring breeze blows to regenerate the combustion (the burning of macromolecular organic matter). 4. The sound of firecrackers is heard, and the spring breeze brings warmth to Tusu. Explosion, gunpowder .5. He Yibai makes steel and turns it into soft steel. 3CO↑+Fe2O3=high temperature=2Fe+3CO2↑, which also has physical melting. 6. When the powder is put into the fire, the color becomes lead.Pb3O4 + 2C — —→ 3Pb + 2CO2↑, ancient alchemy. 7. Hundred-year-old wine with ten lis of fragrance. CH3COOH+CH3CH3OH=CH3COOCH3CH3+H2O (lipidation reaction), ethyl acetate has a fragrance. ⑧. Watch the winemaking of Tang Wangji’s June tune Divine Comedy, heading towards Jimei Spring .It has always been used as spring wine, and it will not last for years without saving. C6H12O6==2C2H5OH+2CO2, anaerobic respiration. 9. It is better than the innocent day of the Yuan Dynasty, and the printed text is verdigris and moss money. 2Cu + O2 + H2O + CO2 ═══ Cu2 (OH)2CO3, copper rusts. 10. Zhumen’s wine and meat stink, and there are frozen bones on the road. Oxidation and decay of organic matter. 11. Stop and sit in the maple forest at night, the frost leaves are redder than the flowers in February. The increase in glucose and the low temperature in autumn It is conducive to the formation of anthocyanins. Therefore, the anthocyanin content gradually increases and the chlorophyll content gradually decreases. Anthocyanin is an unstable organic matter and has no color itself. When it encounters acidic substances, it turns red. Alkaline substances will turn blue. In this way, the anthocyanins turn red in the acidic mesophyll cells, so the leaves turn bright red. 6. Five ancient poems or prose related to chemistry, please ask the masters

There are also many ancient poems describing chemical properties. 1. Li Shangyin's "Untitled": "The silkworm will not be used until the spring silkworm dies, and the wax will be gone." The torch turns to ashes before it dries.

"There are both melting processes in physical changes and combustion phenomena in chemical changes. The component of candles is paraffin, which is a saturated hydrocarbon. It releases heat when burned in the air. Melt solid paraffin into liquid wax. 2. Wang Anshi's "Yuan Ri": "The year is gone with the sound of explosions, and the spring breeze brings warmth into Tusu."

This is a typical chemical change. Firecrackers are generally made of sulfur and other substances, causing After combustion, a chemical reaction occurs to generate new substances such as sulfur dioxide. 3. Liu Kun's "Gift to Lu Chen": "What is meant by hundreds of steel-making, turning it into a finger-winding element". "A hundred steel-making" is actually the process of continuously removing impurities from pig iron and making it pure.

4. Li Bai's "Qiupu Song": "The fire shines on the sky and the earth, and the red stars are scattered with purple smoke." This poem also describes the scene of metal smelting at that time.

5. "Ode of Lime" by Yu Qian of the Ming Dynasty: "Thousands of hammers and thousands of hammers are used to dig out the deep holes, and the fire burns as if it were closed. Don't be afraid of being shattered into pieces. You must leave innocence in the world."

< p> "A thousand hammers and thousands of hammers cut out a deep mountain" describes the difficulty of mining limestone, which refers to physical changes. "The fire burns as if it were idle." In this poem, "the fire burns" refers to the chemical reaction of calcined limestone to produce calcium oxide and Carbon dioxide, coupled with the words "take it easy", makes people feel that it is not only writing about calcined limestone, it also symbolizes that no matter what severe test the people of Zhitu face, they take it easy and take it easy, "shattering their bodies to pieces." "Not afraid" and "Shattered to pieces" embody physical changes and express the spirit of not being afraid of sacrifice. "To leave innocence in the world" is the author's direct expression of his heart, determined to be a pure and innocent person. Another poem by Yu Qian The poem "Ode to Coal": "The black gold is obtained by digging through the chaos, and the sun and the deepest fire are burning to bring back the vastness of spring, and the furnace shines through the dark night. The Ding Yi Yuan relies on the power, the iron and stone still exist in the heart after death, I hope that all the people will be full Warm, working tirelessly to get out of the mountains and forests." The author condenses the formation, characteristics, properties and main uses of coal in the entire poem, and uses the poem to praise the function and quality of coal to express the author's broad mind in dedicating himself to the cause of benefiting the people.
