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>

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>

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>

The subjective reaction was not a mirror reaction. From the perspective of cognition, mirror reaction was a kind of objective reflection like looking in a mirror. This kind of reflection was like a mirror. Whatever the object outside the mirror was, the image in the mirror was the same. It did not change the object itself. It could only reflect the surface phenomenon of things, but could not reflect the essential laws of things. The subjective response contained two meanings. One was that people could actively understand the objective world, and the other was that they could actively transform the objective world under the guidance of their understanding. In the process of subjective reaction, people did not reflect the external world passively, but actively and actively. They could recognize and reflect the essence and laws of things in the practice of changing the object. This was fundamentally different from the mirror reaction that only reflected the surface of things. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The biuret reaction can be used to determine the quality or quantity of the protein. Biuret reagent could react with protein and form a purple complex in an acidic solution. The color was proportional to the concentration of the protein. Therefore, the existence of the protein could be detected by this reaction, and it could also be measured. However, biuret reagents could not be used to detect dipeptides because the reaction required the test substance to have at least two peptidic bonds. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Chloration reaction conditions: - Hot chloridizing: Heat energy is used to stimulate Cl2 to generate a free radical of chloridize, which then reacts with the carbon molecules to form a chloride-containing compound. In the industrial thermal chloridizing process, the ratio of Cl2/CH2 is 1:3 - 4, and the main products are CH Cl2 and CH2 Cl2. Too much Cl2 is easy to explode. The reaction mechanism is a free radical chain reaction, and the composition of the product is related to temperature. - Photo-chloration: Light (commonly used as a light source) is used to excite Cl2 to generate a free radical of Cl2, which then reacts with a hydrogen atom to form a chloride-containing compound. The process is carried out in a liquid phase under mild reaction conditions. - The method of chloridizing by using a catalyst was divided into two types, namely, the uniform and the non-uniform ones. For example, some reactions required high temperature, high pressure, and a catalyst. The ore chloridizing reaction required high temperature, high pressure, and a catalyst. The reaction products were metal chloride-like and hydrogen chloride-like gases. The reaction principle was that the metal elements would undergo an oxido-reduction reaction with the hydrogen. Some organic compounds needed iron and other catalyst for the chloridizing reaction. For example, in the presence of iron catalyst, hydrogen was replaced by chloridize to form chloridize. - For the chloridizing reaction of a specific substance, for example, the preparation of the chloridizing reaction. Oxidation reaction conditions: - [Ores are usually oxided under normal temperature and pressure. The speed and degree of oxidisation are affected by factors such as temperature, humidity, and oxygen concentration. It usually occurs on the surface of ores, causing changes in physical properties such as color, hardness, and density.] - For the thermal reaction of DCl2 in a hydrogen/oxygen mixture, the reaction was carried out in a tube-flow reactor according to the basic thermochemical principles, and the thermal cracking reaction was also studied in the tube-flow reactor. - For the reactions related to propene, it was necessary to prevent local high temperatures and high local Cl2 concentration. Among the reactions of the unsaturation, there were reactions such as the production of 1,2 -diclorethlene from ethene, and the synthesis of ethyne into ethene. The purpose of the oxification of ethene was to utilize the use of the Cl2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The chemical reaction rate represented the speed of the chemical reaction, which was the rate of change of the reaction progress with time or the reaction progress of the chemical reaction in unit time and unit volume. The average reaction rate was the decrease of the concentration of the reagent or the increase of the concentration of the product in unit time. The instantaneous reaction rate was the limit of the average reaction rate that approached zero. The reaction rate constant represented the chemical reaction rate at a unit concentration. It was independent of the concentration, but it was affected by factors such as temperature, catalyst, and solid surface properties. Usually, the larger the reaction rate constant, the faster the reaction would proceed. There were two common methods to measure chemical reaction rates: chemical and physical methods. The chemical method used chemical analysis to directly measure the change in the concentration of the reagent or product over time to obtain the chemical reaction speed. However, the chemical analysis speed might not be able to keep up with the reaction speed and affect the measurement results. However, it could provide an absolute concentration value. The physical method was more extensive and convenient. It was to determine the reaction speed based on some physical properties that changed with the reaction, such as the pressure method, the distension meter method, or the volume method; the optical rotatory method, the interference method, the chromicity method, and the spectrophotosity method; and the electrical property method, such as the conductivity method, the potential method, the polarography method, the dielectrical constant method, and the mass spectrum method. As for the determination of the reaction constant, for example, in the experiment of determining the rate constant of the fading reaction by the method of the catalyst, based on the principle of the catalyst kinetic method, the reaction system of the fading reaction of the Evans Blue by the reaction of the potassium bromate under the action of the NaNO3 was proposed. The corresponding chemical reaction rate constant was calculated by measuring the change of the absorption of the reaction system at different initial concentration and temperature. In terms of specific operations, the stock solution of the relevant reagents was first prepared, and then the reagents were added into the color-measuring tube according to a certain order and dosage. The timing and volume were started, and then the absorption curve was measured. The reaction constant was determined by preparing reaction solutions of different compositions, adding the solution after reacting for a period of time to stop the reaction, and taking a sample to measure the absorption curve. Finally, the concentration of other components was maintained at a constant temperature, and the change of the light absorption with time when different amounts of the solution of bromate or the solution of NaNO3 were measured, as well as the change of the light absorption with time when the specific amount of the solution of NaNO3 was measured at different temperatures. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
