Alkaline Metal Oxides Deliquescence Reaction
Deliquescence is the phenomenon of certain substances absorbing moisture from the air and becoming moist. For basic metal oxide-like CaCl2, MCl2, and NaCl2, deliquescence occurred. However, there was no specific reaction type called the " delixidation reaction of basic metal oxide'. Using the example of dilute ether, deliquescence was a physical change process. It was a process in which the solid state of dilute ether absorbed the moisture in the air and formed a solution on the surface. No new substance was formed, and the reaction equation did not exist. Similarly, the deliquescence of CaCl2 absorbed moisture from the air and became moist. It was essentially a physical change process. Read more exciting novels for free

Alkaline reaction
The following is the reaction of some alklene under basic conditions: - In the nuclopathic epoxidation reaction, the electron deficient alkene could be epoxidized by hydrogen dioxide and tert-butoxyalcohol under basic conditions. Since the reaction was a nuclophile reaction, the epoxiidation could not proceed without an electron withdrawing group. - In the Julia-corona Asymmetrical Epoxidation Reaction, under the catalyst of the chiral-polyalpha-ammo acid, the electron deficient alkene was oxided by an oxidiser (hydrogen or ureido) under basic conditions to obtain a single configuration epoxide. - In the Payne Rearrangement Reaction, 2,3 -epoxy alcohol compounds are converted to 1,2 -epoxy- 3 -ol under basic conditions. This reaction is also known as the epoxy migration reaction. - In the laboratory, the reaction of the lithium salt and the lithium ether could be carried out under basic conditions. The lithium ether had an important catalyst activity in the reaction of alkene and the carbonylating reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Acid and Metal Reaction Color
Different metals may react with acid to produce different colors: - The reaction between the dilute sulfuric acid and the dilute sulfuric acid produced a large number of bubbles. The chemical equation was: Mn +2HQ = Mn Cl2 + Mn Cl2, Mn + Mn Cl2 = Mn Cl2 + Mn Cl2 + Mn - The reaction between the two metals was intense and produced a large number of bubbles. The chemical equation was as follows: Mn +2HQ = Mn Cl2 + Mn Cl2, Mn + Mn Cl2 = Mn Cl2 + Mn Cl2 + Mn Cl2 = Mn Cl2 + Mn Cl2 = Mn Cl2 + Mn Cl2 + Mn Cl2 = Mn Cl2 + Mn Cl2 = Mn Cl2 + Mn Cl2 + Mn Cl2 = Mn Cl - When iron reacted with diluted sulfuric acid or sulfuric acid, a small amount of bubbles appeared on the surface of the nail. At the same time, the solution turned light green because of the formation of iron sulfuric acid or iron chloride.The reaction equation was: FeCl2 <2>+ H <2>, FeCl2 <2>= FeCl2 <2>+ H <2>, FeCl2 <2>= FeCl2 <2>= FeCl2 <2>+ H <2>. - Copper does not react with dilute sulfuric acid or dilute sulfuric acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The Image Problem of the Reaction of Metal and Acid
In the image problem of the reaction of metals with excessive acid, the following situations were mainly involved: ##1. The horizontal coordinate is reaction time. 1. ** Reaction Rate Relationship ** - When different metals react with excess acid, the reaction rate depends on the mobility of the metal. In the middle school chemistry exam, the metal activity was in the order of Mn> Mn. This meant that under the same conditions (such as the same concentration of acid, the same temperature, the size of the metal particles, etc.), the reaction rate from fast to slow was also: Mn> Mn. The image showed the degree of inclination of the diagonal line. The greater the inclination, the faster the reaction speed. 2. ** The final mass of hydrogen produced ** - When the same amount of different metals react with an excess of acid, the mass of hydrogen produced is related to the relative atomic mass of the metal (when the metal has the same valency). According to the chemical equation, the mass relationship of hydrogen produced by the reaction of a metal of the same mass with a sufficient amount of acid was as follows: The higher the platform, the greater the mass of hydrogen produced. ##2. The horizontal coordinate is the mass of the acid. 1. ** Reaction process analysis ** - In the process of increasing the mass of acid, the metal will react completely because there is a small amount of metal (acid excess). The quality of the corresponding acid after the reaction of different metals was different, and the quality of the hydrogen produced was also different. 2. ** Phased analysis of the quality of hydrogen produced ** - At different stages, depending on the activity and relative atomic mass of the metal, there would be different situations where the metal was in excess or completely reacted, which would affect the amount of hydrogen produced. For example, in a certain interval, there may be excessive or complete reaction of the iron, the aluminum, and the aluminum. At this time, the quality of the generated hydrogen would have a specific situation. As the acid quality increased, when entering the next interval, there may be insufficient amount of the iron, or the iron may be excessive or complete reaction. The aluminum and the aluminum may be excessive, and the quality of the hydrogen would change accordingly. ##3. Key Points 1. ** Judging excessive and small amount ** - First of all, he had to judge the excessive and small amount of metal and acid through the description in the question. For example, he could see the words "small amount","sufficient amount","excessive amount", etc. The final amount of hydrogen produced in the reaction was determined by the small amount of the reagent. 2. ** Explain the meaning of the horizontal and vertical coordinates ** - When analyzing the image, it was necessary to distinguish the specific meaning of the horizontal and vertical coordinates in the image. Generally, the vertical coordinate was the amount of hydrogen produced, and the horizontal coordinate might be the reaction time, the mass of acid consumed, or the mass of metal consumed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Which smelting metal is an oxidization reaction?
Metal smelting was mostly an oxido-reduction reaction. In the process of metal smelting, when reducing agents such as carbon, carbon dioxide, and hydrogen react with metal oxides at high temperatures, the reducing agent will undergo an oxidization reaction (the chemical valency will increase and the electrons will be lost), and the metal elements in the metal oxides will undergo a reduction reaction (the chemical valency will decrease and the electrons will be obtained). For example, the thermal reduction method was used to smelt metals. It used a reducing agent with strong thermal reduction properties to reduce the metal from its compound. It was an oxido-reduction reaction that followed the conservation of lost and gained electrons. The coke reduction method, carbon dioxide reduction method, hydrogen reduction method, active metal reduction method, etc. all involved oxido-reduction reactions. In the ancient silver refining process, the cellar mass needed to go through a reduction process (melting silver into lead), and then go through an oxidization process (separation of lead and silver) to obtain raw silver. The oxidization reaction here was the reaction of lead in the furnace ash, separating lead from silver. It was also the embodiment of the principle of the oxidoreduction reaction in metal smelting. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
