When aluminum and oxygen react, do they gain or lose electrons?
The outermost layer of the aluminum atom had three electrons, less than four electrons. When it reacted with oxygen, it was easy to lose the outermost three electrons and form an ion with three units of positive charge. On the other hand, the outermost layer of the oxygen atom had six electrons, so it was easy to obtain electrons in the reaction. Therefore, when aluminum reacted with oxygen, it lost electrons.

Metals lose electrons when they react
Metal was easy to lose electrons in chemical reactions and could only be used as a reducing agent. This was because the number of electrons in the outermost layer of the metal atom was small, and the number of electrons lost during the reaction was equal to the number of electrons in the outermost layer. In the metal activity order table, the higher the position of the metal, the easier it was to lose electrons and become a positive ion. For example, when the metal potassium was put into water, it would react. During this process, the potassium atom would lose its electrons. The essence of the reaction between metals and sulfuric acid was also the interaction between metals, H and NO. In this process, metals lost electrons, just like copper lost electrons when reacting with dilute sulfuric acid. Also, in the process, the metal atoms would lose their electrons and transfer into the medium in the form of ions. This was called the process of the anodoxy process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Magnesium and aluminum can react with oxygen in the air, right? Why?
Magnesium and aluminum can react with oxygen in the air. At room temperature, the polished strip would gradually darken and form a white solid. When ignited, the strip would burn violently and emit a dazzling white light to form a white solid. The chemical equation was 2 Mn + O <2>= ignition = 2 Magnesia. At room temperature, aluminum can react with oxygen to form a dense aluminum dioxide film on the surface of the aluminum, thereby preventing the aluminum from being further oxided. The chemical equation is 4AI +3O <2>= 2AI <2> O <2>. This was because they were relatively active metals, and their chemical properties determined that they could react with oxygen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Magnesium-aluminum and oxygen reaction experiment
The following is related to the experiment of the reaction between magnesium-aluminum and oxygen: ** 1. Reaction between Magnesium and oxygen ** 1. ** Reaction Phenomenon ** - When it burned in the air, it would release heat and emit a dazzling white light, forming a white solid. - The reaction was more intense in oxygen than in air. 2. ** chemical equation **:<2MG + O_{2}><stacking>{=<<=<<=>>>=<>>2MgO\) 3. ** Points to note in the experiment ** - Due to the intense combustion of the titanium, safety must be paid attention to during the experiment and a certain safe distance must be maintained from the titanium. - When burning, it will produce a strong light, which may cause damage to the eyes, so don't look directly at the burning magnetite. ** 2. Reaction between aluminum and oxygen ** 1. ** Reaction Phenomenon ** - When aluminum reacted with oxygen in the air, a layer of dense aluminum dioxide film would be formed on the surface of the aluminum. This film would prevent the aluminum from being further oxided, so the reaction between aluminum and oxygen in the air was not so intense. The surface of the aluminum gradually lost its metallic luster. - If the aluminum foil was heated in oxygen, the aluminum foil would melt, but it would not drip. This was because the melting point of the aluminum dioxide film was very high, and it would hold the molten aluminum and emit a dazzling light during the reaction. 2. ** chemical equation **:<4AI +3O_{2} = 2AI_{2}O_{3}> 3. ** Points to note in the experiment ** - When conducting the experiment of heating the aluminum foil in oxygen, the purity and sufficient supply of oxygen must be ensured. - When heating the aluminum foil, use a suitable heating tool, such as an alcohol lamp, and heat it evenly. ** 3. Experimental design (Comparing the reactions of oxygen with aluminum and aluminum)** 1. ** Experiment Purpose ** - Comparing the intensity of the reaction between aluminum and oxygen, the reaction products, and so on. 2. ** Experiment Steps ** - He took a suitable amount of aluminum foil and a suitable amount of aluminum strip, and polished them to make them bright (to remove the thin film of oxygen on the surface). - Heat the aluminum foil and the aluminum strip separately over the flame of an alcohol lamp (or ignite them in a gas collector filled with oxygen). - Observe and record the intensity of the reaction between the two (such as the reaction of the aluminum strip is more intense, emitting a dazzling white light; the surface of the aluminum foil gradually changes when heated, and it will also emit light when ignited in oxygen, etc.), and the phenomenon during the reaction (such as the combustion of the aluminum strip to form a white solid, the formation of a white aluminum dioxide film on the surface of the aluminum foil, etc.). - After the reaction, the reaction product was analyzed (it could be judged by physical properties such as color and state, or it could be further analyzed by chemical methods). 3. ** Experiment result analysis ** - Based on the intensity of the reaction, it could be judged that the reaction between oxygen and titanium was easier than that of aluminum. - Through the analysis of the reaction products, it could be determined that the reaction between the oxygen and the aluminum formed the aluminum dioxide. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation of aluminum and hydrogen and oxygen
When there was a small amount of oh-ions, the chemical equation of the reaction between aluminum ions and oh ions was: Al3 ++3OH - =Al(OH)3; when there was an excess of oh-ions, the chemical equation of the reaction between aluminum ions and oh ions was: Al3 ++4OH - = AlO2-+2H2O. When a small amount of oh-ions gradually becomes excessive, the chemical equation of the reaction between aluminum ions and oh ions is: AI (OH)3+OH - = AlO2-+2H2O. The ion equation for the reaction of aluminum with water is: 20H- +2Al+2H2O→ 2AlO2-+3H2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Soda and water react with oxygen
Great soda (sodic thionate) could react with carbon dioxide and oxygen in the air. It had to be prepared and used immediately. However, the exact chemical equation of its reaction with water and oxygen was not found. However, it was known that great soda had a reducing property. During use, it would be oxided by the air because of this reducing property. It should be avoided in humid environments to prevent deterioration because it was easy to delixidize in humid air and it might be more likely to react with oxygen and deteriorate in such an environment. At the same time, attention should also be paid to the reduction of nitrogen in aquatic cultivation, which may lead to oxygen consumption and other problems. For example, if soda is used to degrade nitrogen and nitrogen in the middle and late stages of cultivation, it may consume a large amount of dissolved oxygen in the water body due to its strong reduction, causing serious oxygen deficiency in the water body. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Alkaline and aluminum react with an unpleasant smell
If it was a reaction between pure aluminum and aluminum, the gas produced would be H <2>, which had no smell. If there was a pungent smell, it might be because there were impurities in the used soda. In addition, the aluminum nitrogen in the aluminum ash can react with water to produce a pungent odor of hydrogen. If there are aluminum nitrogen impurities in the soda solution, an unpleasant smell may appear during the reaction with aluminum. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Why does aluminum react with alkalium?
The aluminum was a very active metal. At room temperature, pure aluminum would start to react with oxygen in the air to form aluminum dioxide. The aluminum dioxide layer that was formed first would hinder the reaction between oxygen and aluminum. As aluminum dioxide was relatively dense, when the thickness reached a certain (micro-level), the process of the aluminum dioxide layer would stop, and the aluminum dioxide layer formed on the surface would become a protective film. The essence of the reaction between aluminum and base was that aluminum first reacted with water, and the aluminum trioxides produced by the reaction were dissolved in the strong base solution, so the chemical reaction proceeded to the right. It was the reaction between aluminum and the strong base solution. This reaction was an oxidoreduction reaction. The reducing agent was aluminum, and the oxidiser was water. However, when he wrote the ion equation to indicate the direction of electron transfer, the water was eliminated after the addition of the two reaction equations, so he needed to replenish the water. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
