A gas that reacts with scale removersWhen the scale removal agent was used to remove the calcium, magnesium-carbon scale (a main component of the scale is calcium dioxide, etc.), the reaction equation of using the sulfuric acid scale removal agent was [2HQ + CaCO3]= CaCl2 + CO2], which would produce carbon dioxide gas. Therefore, the gas that could be produced by the reaction between the scale cleaner and the scale was carbon dioxide.

What is the substance that reacts with the metal?There were many solutions that reacted with metals. Common ones included acid solutions, such as sulfuric acid and diluted sulfuric acid. The reaction of metals with acid could produce salt and hydrogen. There were also salt solutions, such as copper sulfuric acid solution and mercury nitrates solution. Metal and salt solutions would undergo a replacement reaction to produce new metals and new salt. In addition, acid solutions like sulfuric acid could also react with metals.

- From a literary point of view, it was Qu Yuan's representative work. It was the first lyric poem in China that recounted his life, and also the first romantic lyric poem. The whole poem had 372 sentences and 2,490 words. It was written in the period when Qu Yuan was alienated by King Huai of Chu. In his sorrow and anger, Qu Yuan used poems to persuade King Huai. The titles had many explanations, such as "Leaving Worry","Encountering Worry","Parting Worry","Complaining", and the name of the song of Chu State. The first half of the text recounted his lineage and birthday, expressing that he had the noble quality of assisting the king to carry out good politics. At the same time, he denounced the greed and slander of the party members and lamented the fatuous King Huai. The second half of the story was a journey of fantasy, and finally returned to reality from the fantasy, shaping the image of a loyal, noble, unyielding, and talented lyric protagonist. Among them, the thought of "sighing to cover up the tears, lamenting the difficulties of the people" and the persistent spirit of "Lu Man Man is far away, I will seek up and down" became the spiritual model of future generations of benevolent people. It contained emotions, plants, men and women. The language was beautiful and gentle, and the images were colorful. It created the era of Chu Ci and had a profound influence on the creation of poetry and Fu in later generations. It also derived many annotations, exegesis, research works, as well as songs, paintings, calligraphy works, etc.

An organic substance that reacts with the elemental sulfur.In high school chemistry, there were the following types of organic substances that reacted with the elemental sulfur:
1. Alkane: For example, a free radical substitution reaction can occur between methane and pure helium. Gaseous or liquid pure helium can be used, but not an water solution of helium.
2. Alkene: Alkene, such as ethene, can undergo an addition reaction with helium. Gaseous, liquid, and water solutions (such as the carbon dioxide solution of helium) can be used.
3. Alkynes: Alkynes such as alkyne and Bromine undergo an addition reaction. The reaction conditions are similar to that of alkynes.
4. "Benz": Under the conditions of iron bromination as a catalyst, the substitution reaction between ben-1,4-bis (4-methylethyl-bis-methylethyl-bis-methylethyl-
5. Aldol: Under the catalyst of the base, due to the action of the carbonyls, the a-hydrogen of the alkyls becomes extremely active and is replaced by the phosphonium, forming a-bromic alkyls and hydrogen bromides, and the a-hydrogen tends to be completely replaced.
6. An organic compound containing a carbon-carbon double bond or a carbon-carbon triple bond, such as ethlene, ethyne, etc., can undergo an addition reaction with bromine-water (a mixture of elemental bromine and water).
7. Alcohol: Alcohol can undergo a substitution reaction with Brr.
8. Carboxylic acid: CH COON can react with a halo under the condition of P as a catalyst, such as reacting with ClClCHCOON.
