What is the essence of the cell's oxidoreduction reaction?
The essence of the cell's oxidoreduction reaction was the transfer of electrons. The electron transfer was a microscopic phenomenon, and it was reflected in the change of the chemical valency (namely, the number of electrons) on the macro level. The reaction of losing electrons with an increase in the oxygen number was an oxygen reaction, and the reaction of gaining electrons with a decrease in the oxygen number was a reduction reaction.

Is scale removal an oxidoreduction reaction?
Whether or not the scale removal was an oxido-reduction reaction depended on the scale removal method. If edible vinegar was used to remove the scale, the reaction between edible vinegar (the main component of the vinegar) and the scale (the main component of the vinegar) was not a reduction reaction. The reaction produced calcium acetate, carbon dioxide, and water. There was no electron transfer or shift during the reaction, and the valency of the elements did not change. However, if you use some scale removers with specific components, such as pipeline scavengers that reduce the activity of microorganisms through a reduction reaction, this process involves a reduction reaction, but this is not a common type of scale removal reaction. Therefore, scale removal was not necessarily a reduction reaction. It depended on the method of scale removal and the chemical reaction involved. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
the catalyze alcohol and that water participate in the oxidoreduction reaction
The reaction between the aromatic compounds and water was generally not a reduction reaction. The typical reaction of the aromatic compounds is C2H5Br2 +H2O(heated solution of NaOx) → → C2H50H + Brr, which is a type of substitution reaction, not a reduction reaction. Even though these compounds were polar, it was rare for them to react with water. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is there an energy change in the oxidoreduction reaction? Why is it unchanged?
Your question is a little messy. There was an energy change in the oxidoreduction reaction. This was because in the oxidoreduction reaction, the chemical bond of the reagent was broken to absorb energy, and the chemical bond of the product was formed to release energy. This absorption and release produced a change in energy. For example, the common combustion reaction was the oxidoreduction reaction, which would release heat. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The Essence of the Reaction of Salt and Salt
氯化铵与氢氧化镁反应的实质可从以下方面分析。氯化铵是强酸弱碱盐，在水中发生水解产生氢离子，即\(NH_{4}^{+}+H_{2}O = NH_{3}\cdot H_{2}O + H^{+}\)。氢氧化镁难溶于水，但氢离子能与氢氧化镁中的氢氧根离子反应，即\(Mg(OH)_{2}+2H^{+}=Mg^{2 + }+2H_{2}O\)，从而促使氢氧化镁溶解。 从另一个角度看，这一反应也可理解为氢氧化镁沉淀能溶解于铵盐中。因为铵盐（如氯化铵）存在时，铵根离子与氢氧根离子结合，使氢氧根离子浓度降低，例如\(MgCl_{2}+2NH_{4}OH \rightleftharpoons 2NH_{4}Cl + Mg(OH)_{2}\downarrow\)这个可逆反应，当氯化铵大量存在时，平衡向左移动，沉淀溶解。此外，该反应也有气体生成推动反应进行的因素。 <a href="/?from=ask_words" style="color:red" target="_blank">点击前往免费阅读更多精彩小说</a>
The Essence of Ferrous Sulphate Reaction
The nature of the reaction depended on the type of reaction. For example, in some reactions, it was actually a metathesis reaction, which would form a deposit. In the reaction related to oxygen, due to the reduction of the iron, the iron will be oxided in the presence of the hydrogen to form the hydrogen of the iron. Under acidic conditions, it will be oxided by oxygen to form the hydrogen of the iron and water. Ferrous ions would also undergo a decomposition reaction in water, combining with the water's free radical ions to form a deposit of Ferrous Oxides. However, this decomposition reaction was irreversible. In a solution with a strong acid, a high concentration of hydrogen ions would suppress the decomposition reaction of the Ferrous Ion. In addition, Ferrous Sulphate was an acidic substance, which would neutralize with an acidic substance. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Blood cell C-reaction protein 75
C-reaction protein 75 was a relatively obvious increase, which could be caused by many factors. The concentration of C-reaction protein in a normal human body is about less than 2.87 milligrams per liter.(Different testing methods and institutions may have slight fluctuations, generally between 0 - 8 milligrams per liter.) When the body has suppurative infection, cardiovascular disease, severe trauma, major surgery, burns, malignant tumors, Connective tissue disease, acute rejection of organ transplantation, etc., the concentration of C-responsive protein will increase. For children, bacteria, viruses, Kawasaki disease, rheumatism immune diseases, or vaccine may cause it to increase. Although elevated C-reaction protein may indicate an increased likelihood of a bacteria infection,(For example, when the CPR is higher than 20 milligrams per liter, the doctor will think that the possibility of being infected by bacteria is higher, but this is not absolute. It also needs to be combined with the changes in white blood cells and other comprehensive judgments.) However, inflammation does not mean that it is a bacteria infection, nor does it mean that anti-inflammatory drugs need to be used. For example, the CPR of viral infection is often higher than 10 - 40. As the CPR increases further, the possibility of bacteria infection will increase. In the China Evidence-based guidelines for acute fever in 0 - 5 years of age, when the CPR was greater than 40, the possibility of diagnosis of serious bacteria infection was higher, and when the CPR was greater than 80, the possibility of diagnosis of serious bacteria infection was higher, but even so, it was not absolute. If one wanted to completely assess the severity of a patient's condition, they could not rely solely on C-reaction protein. They should combine the patient's overall symptoms, physical signs, and more laboratory test results to make a judgment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Multinucellated Giant Cell Reaction in Mammary Ducts
Multicaryotic giant cell reaction in the breast duct may be associated with a variety of breast disease conditions. Multinucellated giant cells could be seen in the stroma around the breast duct tumors and breast cysts. There were polynuclear giant cells, mononuleus, epitheid-like cells, and infiltration of plasma cells in the stroma around the breast cysts. In some breast tissues after treatment, such as some breast cancer patients who received neoadjutant chemotherapy, there was also a reaction of polynuclear giant cells in the breast stroma. Multinuleated giant cells in the breast were generally a response to some chronic infections. The substances secreted by the multinuleated cells could kill biological viruses. This was a change in excessive reproduction, accompanied by the engulfment of tissue cells. However, excessive expression could sometimes lead to allergy and other immune reactions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the essence of the reaction between nitrogen dioxide and water
The essence of the reaction between nitrogen dioxide and water was that the nitrogen element would undergo its own oxido-reduction reaction. In the reaction, 3 <2> NO <2>+ H <2> O = NO +2HNO <2>, 3 moles of +4-valency nitrogen element, 2 moles of which are oxided into +5-valency nitrogen element, losing 2 moles of electrons, forming 2 moles of sulfuric acid;1 mole is reduced to +2-valency nitrogen element, obtaining 2 moles of electrons, forming 1 mole of nitrogen dioxide. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The essence of the reaction between the solution of soda ash and hydrogen ClCl3 is
The essence of the reaction between the solution of carbon dioxide and hydrogen dioxide was the reaction of carbon dioxide ions and hydrogen ions. The reaction process was the step reaction of carbon dioxide + hydrogen ions-hydrogen carbonate-carbon dioxide. When hydrogen dioxide was added into the solution of hydrogen dioxide drop by drop, due to the small amount of acid, hydrogen ions were directly taken away by the carbon dioxide radical to form hydrogen dioxide radical ions. When the acid was excessive, the hydrogen dioxide radical ions combined with the hydrogen ions, and the metathesis reaction produced carbon dioxide. When the solution of hydrogen dioxide was added into the solution of hydrogen dioxide drop by drop, due to the excessive amount of hydrogen dioxide, the two directly metathesized to produce carbon dioxide and salt. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
