The reaction between the acid and the acid would result in the formation of a sulfuric acid deposit. The reaction equation was Na Chi SiOx +2HNOOx == H Chi SiOx +2NaNOOx, and the reaction phenomenon was the formation of a white deposit. In this reaction, the sulfuric acid did not show any oxidisation, but only showed its acidic nature. This was because the silicon in the silica was already in the highest state, and the acidic nature of the sulfuric acid was stronger than that of the sulfuric acid, which was in line with the principle of making a weak acid from a strong acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There is no chemical reaction between NaCl2 and magnesiumcarbonate2. In chemistry, the conditions for metathesis reactions to occur were the formation of precipitations, gases, or water. After mixing the two, the conditions for the metathesis reaction were not met, so there was no reaction, no reaction equation, and no reaction phenomenon. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Aluminiothermic reaction was a kind of oxide-reduction reaction between aluminum and metal or non-metal compounds at high temperatures. Aluminiothermic reaction was an exhaling reaction, and its heat release was very large, usually enough to heat the product above the melting point, and the reaction could generally occur locally and be self-sustaining. This characteristic also reflected the energy-saving characteristics of the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The secret at the bottom of Ye Qingmei's lake was the forbidden door. According to the contents of Ye Qingmei's letter to Fan Xian, the forbidden door at the bottom of the lake was the final location of all secrets. Taiping Courtyard was the place where Ye Qingmei lived for a long time. It was also the place where she, the Qing Emperor, Chen Pingping, Fan Jian, and the others had been carefree when they were young. The specific secret content could be found in the 121st chapter of << Celebrating Years >>.

Rearrangement reaction refers to the migration of certain atoms or groups in the molecules of organic compounds under certain reaction conditions, resulting in the reorganization of the molecular structure. For example, the Beckmann Rearrangement Reaction was a reaction in which ketoximes were rearranged into N-substituted diamides under the action of an acidic catalyst; the Cope Rearrangement Reaction was a (3,3)-sigma-shift rearranging reaction of 1,5 -diene; the Hofmann-Martius Rearrangement Reaction was a reaction in which N-alkylated aromatic compounds were rearranged to the corresponding o-/p-alkylated aromatic compounds under the action of acid catalyst; the Curtius Rearrangement Reaction was a type of nuclopathic rearrangements. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Esterification reaction was a irreversible reaction, and it was very difficult to achieve a complete reaction. In the esterfication reaction, the ester could be synthesized from the mixture of ether and alcohol. At the same time, the ester could also be decomposed into ether and alcohol by reacting with water. The direction of the reaction depended largely on the content of various substances in the reaction environment. When the content of one of the substances on the left side of the equation (such as vinegar and alcohol) was very high, the reaction would tend to form an ester, but it was still difficult to achieve a complete reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Additional reaction: - The addition reaction of ethene and Bromine: <<CH2 = CH2 + Br2> - The addition reaction of ethene and hydrogen bromidate was as follows: <CH2 = CH2> - Under certain conditions, addition reactions could also occur between ethene, hydrogen, and water. Since the chemical properties of ethyne (carbon-carbon triple bond) were similar to that of alkene (carbon-carbon double bond), similar addition reactions could also occur. - The aromatic ring can undergo an addition reaction with hydrogen (in the presence of a catalyst such as Ni). - Aldol groups can undergo a reduction reaction (addition reaction), such as: <anno data-annotation-id ="00000000 - 4c00 - 4c00 - 8c00 - 9c00 - 9c000b000000"> CH3CH20H </anno>. Substitution reaction: - The substitution reaction between methane and Cl2: CH4 + Cl2. - The substitution reaction of the aromatic ring: For example, the substitution reaction with the aromatic group using FeBr3 as a catalyst; the nitration reaction with the aromatic group using concentrated sulfuric acid under heating conditions (the hydrogen on the aromatic ring is replaced by the nitrogen group). - The substitution reaction of the halated carbon was as follows: <<CH3CH2Br2>+<NaBr2>>. - The substitution reaction of alcohol: <CH3CH20H>+<br>> longrightarrow <CH3CH2br>+<H2O>> - The ester's cleavage reaction (which can be seen as a substitution reaction):<CH3COOCH2CH3 + H2O> <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

You might want to ask about the three pools that reflect the moon in West Lake, Hangzhou. The three pools reflecting the moon was one of the ten scenic spots of the West Lake in Hangzhou. It was known as the "first scenic spot of the West Lake". It was located in the southwest waters of the West Lake, also known as "Little Yingzhou". It was famous for its water-based gardens and moon-viewing. It included the three stone pagodas on the south side of the island and the Little Yingzhou. It was the largest island in the West Lake scenic area, covering an area of 7.67 hectares. The Three Pools Mirrors the Moon was built in the Song Dynasty. In the fifth year of Yuanyou of the Northern Song Dynasty (1090), Su Shi built three pagodas as a symbol when he governed the West Lake, and the three pools printed the moon. During the Wanli period of the Ming Dynasty, a series of constructions formed the "Little Yingzhou". During the Yongzheng and Guangxu years of the Qing Dynasty, there were repairs and renovations. There were many beautiful legends here. One theory was that after a candle was lit in a hollow cave, the reflection of the water would appear on the surface of the lake like the moon imprinted in the water, hence the name. There was also a legend that the water god of West Lake, Qian Tang, planted three pearls to cure his mother's eye disease and turned them into bright moons to illuminate the center of the lake. The three pools reflecting the moon were also known as the "Three Yuan Pool." In addition, on the night of the Mid-Autumn Festival, the moonlight shone through the thin paper pasted on the entrance of the cave and shone on the five equally-spaced round holes arranged on the spherical body. The holes were printed into the lake, showing many moons. It was difficult to distinguish between real and fake, and the night scene was very charming. It was also the background picture of the one-yuan note. There were many scenic spots on the island, such as the Nine Lion Stone, the Open Net Pavilion, the My Heart Pavilion, the Nine Winding Bridge, the Three Pools Moon Imperial Stele Pavilion, etc. The cultural landscape was concentrated at the northern end of the island. During the day, you can take a boat to visit the island from many docks.

Fever usually occurred within 1 - 2 hours after blood transfusion. It was often accompanied by chills or chills, followed by high fever. The body temperature could reach 39 - 40 ° C, accompanied by skin flushing and headache. Most of the blood pressure did not change. The symptoms lasted for less than 10 minutes and relieved after 1 - 2 hours. Some patients might be accompanied by nausea, vomiting and other symptoms. Most hemolytic reactions were caused by the transfusion of abnormal blood. The typical symptoms were shock, chills, high fever, difficulty breathing, back pain, precordium pressure, headache, hemoglobinuria, abnormal bleeding, and so on, which could lead to death. The only early signs of surgery patients under anesthesia were wound bleeding and low blood pressure. Compared to hemolytic reactions, fever reactions during blood transfusion were usually milder, but hemolytic reactions were more serious and even life-threatening. In addition, from the mechanism of the fever reaction, it was different from the hemolyzed reaction. The hemolyzed reaction was an acute immune transfusion reaction caused by the reaction of the transfused red blood cells (a few of which were the red blood cells of the recipient) with the corresponding red blood cell allo-antigen-like body of the recipient. In terms of treatment, there were also differences between the two. Blood transfusion should be stopped immediately for fevers, and heat preservation should be given when shivering, and fever should be treated with antipyretic treatment. For hemolytics, more complicated and urgent treatment measures should be carried out according to the specific situation, such as dealing with possible serious consequences such as shock and acute kidney failure. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
