What is the reaction of the aluminum thermal reaction? Is it an exhalation reaction?
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.

What is the reaction of the rearrange reaction?
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.

Which one is the heat absorbing reaction, the oxidization reaction or the reduction reaction?
Oxidation and reduction reactions occurred simultaneously in a single oxido-reduction reaction. It could not simply be said that either of the reactions was heat absorbing. Oxidation-reduction reactions could be both heat absorbing and heat releasing. For example, the combustion reaction was an oxido-reduction reaction and was an exhalation reaction, while the formation of water gas was an absorption reaction.

The Determination of Reaction Rate and Reaction Constant
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.

Distinguishing Fever Reaction and Hemolytic Reaction
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.

Is 'Buffy Suicide Fanfic' a common genre in the Buffy fanfic community?
Not really. While there might be a few 'Buffy Suicide Fanfic' out there, they are not common. The Buffyverse is known for its action, magic, and complex characters. Most fanfic writers are interested in expanding on these elements rather than delving into such a distressing and controversial topic. Also, many fanfic communities have rules against writing about topics like suicide in a way that could be harmful or triggering.

Reaction Formula and Condition of the Reaction of the Acid and the Acid
Under normal circumstances, the reaction between the two could not be carried out directly. Because the lone pair of electrons of the oxygen of the alcoholic group was coupled with the aromatic ring, the reaction activity was very weak, and it could not be used to catalyze the ester reaction with the acid. To synthesize the ester, the reaction of an acid acid or an acid ether with the ether was usually done. For example, the reaction between the ether and the ether was: C6H50H +(CH3CO) 2O = CH3COOC6H5 + CH3COON.

Is water absorption a chemical reaction or a physical reaction
Water absorption was usually a physical property that was reflected in physical changes, but some also involved chemical changes. For example, the solid state of soda ash had a strong moisture absorption. It absorbed the surrounding water vapor and dissolved in the absorbed water, forming a concentrated solution of soda ash. This process was a physical change. The concentrated sulfuric acid could absorb the water vapor in the air around it to form a series of water compounds. On the other hand, the concentrated sulfuric acid dissolved in the absorbed water to make itself thinner, which also involved physical changes. However, the concentrated sulfuric acid absorbed the first water molecules in the copper sulfuric acid, which reflected the water absorption (physical property), and the removal of the remaining four water molecules reflected the dehydration (chemical property). The main component of the quicklime drying agent was lime, and its water absorption ability was achieved through a chemical reaction. This water absorption was irreversible.
