The reaction phenomenon of the reaction of nitrates and the reaction of the reaction of the nitrates and the sodiumsThe 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.

Reaction Formula of Substitution Reaction for the addition reaction of organic substancesAdditional 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>

To write glory or to express glory" Writing " and " describing " could both be used in the context of " glory ", but the meaning was slightly different. The " writing " in " writing glory " focused on creating and recording glorious experiences or achievements like writing words. This expression was more solemn and objective. It emphasized a practical action or process, such as the process of people using their own efforts, wisdom, and actions to create brilliant achievements in history, career, and other aspects. The description of glory emphasized on expressing the emotions and meaning of glory. It was more emotional and emphasized the subjective emotional expression and rendering of glory. The exact word used depended on whether the emphasis was on the glorious record creation process or the emotional expression of glory.

Distinguishing Fever Reaction and Hemolytic ReactionFever 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.

The Determination of Reaction Rate and Reaction ConstantThe 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.
