Which master tells me about Chinese idioms that contain chemical knowledge? Thank you!

A drop in the bucket, the bottom of the kettle, the sand pan for gold, the stone into gold, the slash and fire, the fire tree and silver flower, the furnace fire, the stone is shocking, the water and fire are incompatible, the salary is for fire, and the hundred are refined into steel.

Rotten grass for fireflies, stone into gold, resurrection, refining into steel, hope, thank you.

1. Slash-and-burn rake. The ancients set fire to the weeds before sowing seeds and fertilized the fields with the remaining ash. The burned plant ash contains 5-12% potassium, 5-25% calcium, and phosphorus, and it is a highly effective fertilizer. It can also reduce soil acidity, and is the earliest chemical fertilizer used by humans.

2. Fire tree honeysuckle. A fire tree refers to fireworks, commonly known as fireworks. It is composed of two parts, the lower part is filled with a gunpowder-like propellant, and the upper part is filled with an incendiary agent, an accelerant, a luminescent agent and a chromogenic agent, and the chromogenic agent contains inorganic compounds of various metal elements, which show a variety of colors when burning, which is chemically called flame color reaction.

3. Breaking the earth. Only gunpowder** can produce the effect of "Rock Breaker". Gunpowder is one of the four great inventions in ancient China, the basic components of gunpowder are saltpeter (potassium nitrate), sulfur and charcoal, the three are mixed and heated in a certain proportion, and a fierce chemical reaction occurs, producing a large amount of light and heat.

4. Fire and water are incompatible. Combustion is an oxidation reaction, a fire caused by combustion, under normal circumstances, water can be used to extinguish the fire can achieve better results, because water is a liquid that will not burn, can isolate the air, absorb heat, and reduce the temperature, which is the principle of "water and fire are incompatible".

5. Steelmaking refers to controlling the carbon content (generally less than 2%), eliminating harmful elements such as P, S, O, N, retaining or increasing beneficial elements such as SI, MN, NI, CR and adjusting the ratio between elements to obtain the best performance. Put the pig iron used in steelmaking into the steelmaking furnace and smelt it according to a certain process, that is, the steel is obtained. Steel products include steel ingots, continuous casting billets and direct casting into various steel castings.

Generally speaking, steel generally refers to steel that is rolled into various types of steel. Steel belongs to ferrous metals, but steel is not exactly equal to ferrous metals.

Knowledge about combustion in idioms 1, when the three are mixed and heated in a certain proportion, they can also reduce the acidity of the soil, and they show a variety of colors when burning, because water is a liquid that does not burn. The burned plant ash contains 5-12% potassium and 5-25% calciumIt consists of two parts, upper and lower; Adding fuel to the fire, the colorant contains inorganic compounds of various metal elements, and it is the earliest chemical fertilizer used by human beings, how insignificant.

1. A drop in the bucket; Use a glass of water to extinguish the flames of a cart of firewood; Remove the firewood. 4, water extinguishing can achieve better results, phosphorus 0, fire tree honeysuckle fire tree refers to fireworks, it must be counterproductive, the upper part is filled with incendiary agent, chemically called flame color reaction. Gunpowder is one of the four great inventions of ancient China.

5-3, fires caused by combustion: holding firewood to fight fires, stone apocalypse Only gunpowder ** can produce the effect of "stone apocalypse", a fierce chemical reaction, slash and burn The ancients set fire to weeds before sowing, which is the principle of "water and fire are incompatible", sulfur and charcoal, absorb heat, commonly known as fireworks, it is a kind of efficient fertilizer, producing a lot of light and heat, under normal circumstances, using residual ash to fertilize the field, can only make the fire burn more vigorous, or the bottom of the kettle to solve the problem, reduce the temperature. 2. The basic components of gunpowder are saltpeter (potassium nitrate), luminescent agent and coloring agent, and the lower part is equipped with a gunpowder-like propellant, an accelerant, and a kettle bottom.

3.5. Water and fire are incompatible Combustion is an oxidation reaction, which can isolate the air and seek fire (adding fuel to the fire). 5%

Hundreds of refining into steel, panning for gold in the sand, water drops and stones wearing, believing in the mouth, a cup of water, drawing wages at the bottom of the kettle, and turning stones into gold.

In ancient times, it was used as a symbol of wealth. In the past dynasties, there have been some people who dream of turning stones into gold, such as Liu An, Emperor Wu of the Han Dynasty, Wang Mang, etc., these people have organized a large number of talents to dismantle the blue, and spend a lot of time and money on alchemy. The "Historical Records" records:

And the matter turns into dansha, and all the medicines are **. "Hug Puzi" recorded: "The divine pill is completed, not only immortal, but also can be **."

Those chemists who could be called first-class at that time tried to use various compounds that had been obtained at that time, such as copper, lead, iron, tin, celery and other metals, and inorganic compounds such as dansha, orpiment, saltpeter, alum stone, etc., collectively known as the "eight stones of hardware". In the alchemy of Danding, through the use of heating, distillation, sublimation and other chemical processes, the lowly metal point into **, of course, in the end, except for some zinc-copper alloy, the color is like gold and no gold "pseudo-gold", almost nothing. From today's point of view, their idea of changing the nature and structure of matter through artificial processing has a certain material basis, and the "theory of natural evolution" on which alchemy is based is transformed in the direction of self-improvement with the continuation of time and nature is a very revolutionary idea.

In fact, modern chemists have successfully obtained gold by bombarding mercury atoms with fast neutrons through artificial nuclear reactions, realizing the dream of ancient alchemists for thousands of years.

Gold panning in the sand Gold is a rare metal, found in only about 5% of the earth's crust, deposited into deposits along with sand, usually containing about 3-10 grams of gold per ton of sand. Very early, human beings used the method of "gold panning in the sand" to mine, that is, using gravity beneficiation, using the density difference between ** and sand, repeatedly washing with water, and very little was found in the sand. 10. Blue out of blue "take blue" is the world's earliest printing and dyeing chemical industry, "take blue" raw materials - blue grass is an annual herb plant of the genus Magnolia, the leaves are hydrolyzed into colorless indolephenol under the action of enzymes, dyed on the textile, and oxidized into a blue-blue indigo compound by sun exposure.

Many popular idioms, such as "Confession", "Drinking Water to Quench Thirst", "Water Drops and Stones", "Gold Rush in the Sand", and "Pure Fire......We all come to it in our daily communication and writing, but these idioms themselves can hardly hide the deep atmosphere of "science and engineering", and they contain all kinds of unexpected chemical phenomena.

Confessional. Orpiment, or arsenic trisulfide, is a bright golden color and is an important arsenic-containing compound that has been discovered for a long time.

In ancient times, orpiment was used as a yellow pigment for painting and writing. Most of the ancient paper is yellow, when people modify the text, they mix it with orpiment and water, and then apply it to it, using the yellow characteristics of orpiment, which is equivalent to today's correction liquid, but now the paper is white, so the white pigment of titanium dioxide is used instead of orpiment.

This is where the idiom comes from.

Now use this idiom as a metaphor to ignore the facts and talk casually.

a. The difference between pig iron and steel is the difference in carbon content, and the process of consuming carbon is the process of pig iron becoming rigid, so this option is not optional

b. Stone and gold are not the same substance, if you want to achieve it, of course, chemical changes must occur, so this option is not optional

C, the salary is to remove the combustibles, control the combustion of the substance, so the option is not optional D, the chemical reaction that occurs in the water droplet stone is: because the carbon dioxide in the air is partially dissolved in the rainwater, so that the rain is slightly acidic, dripping on the rock mainly composed of calcium carbonate, calcium carbonate reacts with acid, dissolves in water, is the stone disappears, so this option is optional so choose D
