What are the reactions and phenomena of lime?
Lime reactions were as follows: - ** Lime cracking phenomenon **: If lime is carried in the raw materials or Cao is carried in the internal fuel (fly ash, slag), over-burned lime will be produced during the high-temperature smelting process. The overheated lime absorbed water and expanded in the brick body, which might cause the brick body to expand and damage. - ** Lime shaft kiln over-burning phenomenon **: During the lime roasting process, due to the high temperature or long time, the limestone in the limestone is over-decomposed, resulting in over-burned lime. Its appearance color is darker, the surface is hard and smooth, the particles are larger and irregular in shape; the chemical composition is low in calcium dioxide content and high in calcium dioxide content; the physical properties are high in density, low in void rate, small in contact area with water, and low in reaction rate. - ** Reaction between quicklime and water **: Under normal conditions, quicklime will undergo a violent chemical reaction when it meets water, forming calcium dioxide (slaked lime) and releasing a large amount of heat, causing water to boil when heated. The reaction equation was: CaO2 + H2O = CaO2. The specific reaction phenomenon was divided into two situations. One was to pour water into quicklime powder, and the water gradually boiled and evaporated, turning gray and turbid halfway. The second was to put quicklime into water, and the lime gradually dissolved and generated heat. If the two were strictly equal and fully reacted at the same time, the phenomenon would be close to the first situation. In addition, white water vapor could be seen when quicklime reacted with water. Quicklime gradually dissolved and completely dissolved into a clear solution after adding enough water, but calcium hydrogen was slightly dissolved. - ** Phenomenon of adding lime into saturated lime water **: - ** Adding excessive CaO2 **: CaO2 and the water in the lime water continuously react to form CaOx. The amount of the solution, the solute, and the solute continuously decrease until they all become 0. CaOx increases with the reaction and remains unchanged after the reaction. - ** Add a small amount of CaO**: CaO consumes a small amount of water and the reaction is heat. The consumption of water reduced the release of solute from the solution, and the heat release reduced the solute release from the calcium hydrogen, reducing the mass of solute and solution. When the reaction temperature gradually decreased and returned to room temperature, the solid that was separated due to the decrease in dissolution would dissolve again, and the solute and solution would increase again, but in the end, it would be smaller than the original saturated solution and solute. As for the solute mass fraction, when a small amount of CaO2 was added, the reaction temperature decreased to room temperature, and the solute mass fraction gradually increased to the original mass fraction. - ** Reaction of quicklime with carbon dioxide and water **: The reaction of quicklime with water will produce CaCl3, which is slightly dissolved in water. The reaction of CaCl3 with water and carbon dioxide will produce CaCl3. For example, after quicklime was dissolved in water, if it came into contact with carbon dioxide, it might produce a white deposit after standing for a day. The upper layer of clear liquid was calcium hydrogen, and when it was blown into it, it would become turbid, and then it would become clear. - ** Reaction between quicklime and cola **: Quicklime is dissolved in water to form calcium hydrogen and releases a lot of heat, causing the carbon dioxide in the cola to decompose into carbon dioxide and produce a lot of bubbles. After standing for a day, it will produce a white deposit (When the temperature returns to room temperature, carbon dioxide and calcium hydrogen react to form calcium dioxide).

Is it a cultural relic or calligraphy?
This question was not very clear. If you wanted to ask if a specific item was a cultural relic or calligraphy, you needed to provide relevant information about the item to answer. If it was about the distinction between cultural relics and calligraphy, cultural relics were relics and relics left behind by human social activities with historical, artistic, and scientific value, including buildings, living utensils, various works of art, etc. If a calligraphy work met these characteristics, it could be identified as a cultural relic. Calligraphy was an art form, the art of writing. It mainly used Chinese characters as the object of expression. The writer used writing tools such as a brush to write according to a certain style, structure, and composition. Many calligraphy works had become cultural relics because of their age and high artistic value. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The girl replied to the boy with a curtain word
Just from the word "curtain" itself, it had many meanings in ancient culture. It could be used to cover doors and windows, such as curtains, curtains, etc., with the function of separating space and protecting privacy. From the perspective of poetic images, the "curtain" had a subtle relationship between separation and penetration. It seemed to be separated but not separated, and it could create a hazy beauty. If the girl replied to the boy with the word " curtain," it might imply that there was some kind of vague estrangement between the two of them, or it might be a more implicit expression of wanting to keep a certain distance. It might also be a euphemistic and poetic way to respond to the boy with the help of the elegant image of " curtain " in classical culture. The specific meaning might need to be judged in combination with the specific situation and relationship between the two.

What is the reaction phenomenon of iron trioxid and potassium iodate?
When the reaction between iron (III) and potassium iodate was carried out, the reaction equation would be: [[Fe2 (Ox) 3 + 2Ki = Fe2 (Ox) 2 + I2 + 2kOx] if the iron (III) was in excess, and the reaction equation would be: [Fe3 (Ox) 3 + 3Ki = Fe2 (Ox) 2 + KI3 + 2kOx] if the amount of potassium iodate was in excess ([I2] and [I3 ^-] could form a complex ion). The reaction phenomenon was that there would be the formation of elemental iodines in the solution (when there was an excess of iron dioxide, it would form free elemental iodines, and when there was an excess of potassium iodinate, it would form a complex ion of <<I3 ^->>), and at the same time, iron dioxide would be reduced to iron dioxide. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Zhurong is Gonggong's father.
There were different opinions on whether Zhurong was Gonggong's father. One theory was that according to the records of the Classic of Mountains and Seas, the wife of Emperor Yan and the son of Chishui, Tingyu, gave birth to Yanju, Yanju gave birth to Jiebing, Jiebing gave birth to Xiqi, Xiqi gave birth to Zhurong, Zhurong descended into the river and gave birth to Gonggong. From this record, Zhurong was Gonggong's father. However, there were also people who believed that Zhurong was just a title of a divine title. Zhurong, who fought against Gonggong, was not Gonggong's father. Gonggong's bloodline was the descendants of Emperor Yan, while the one who fought against Gonggong was the descendant of Emperor Huang. Had he not watched enough of Long Lovesickness 2?
