The reaction between aluminum and oxygen forms aluminum dioxide, and its chemical equation is 4AI +3O <2>= 2AI <2> O. This chemical expression did not change for the following reasons: 1. The law of conservation of atoms: In a chemical reaction, atoms will not be created or destroyed, they will only be reassembled. The type and number of aluminum atoms and oxygen atoms remained unchanged before and after the reaction. Before the reaction, aluminum was a single aluminum atom, and after the reaction, it existed in the aluminum dioxide molecules. Before the reaction, oxygen atoms existed in the form of oxygen molecules, and after the reaction, they existed in the aluminum dioxide molecules. 2. ** The chemical properties of aluminum and oxygen are stable. ** When aluminum reacts with oxygen, due to the outermost electronic structure of the aluminum atom, it tends to lose electrons and combine with oxygen atoms to form a stable compound structure such as aluminum dioxide. There were covalent bonds between the oxygen atoms in the oxygen molecules. When it reacted with aluminum, this covalent bond was broken and reassembled with the aluminum atoms to form a new chemical bond. The aluminum dioxide structure formed after the reaction was stable, allowing the reaction to proceed according to this chemical equation. 3. ** Energy angle **: This reaction is carried out according to 4AI +3O ^= 2AI ^O ^, and the energy before and after the reaction reaches a stable state. In the energy conversion process from the reagents aluminum and oxygen to the product aluminum dioxide, this relationship between the two allowed the reaction to occur in the most stable energy state, and under certain reaction conditions (room temperature or ignition, etc.), it was the only energy-favorable reaction method. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In a magnesium-aluminum battery (negative electrode-aluminum, positive electrode-aluminum, and an eletrolyte-lithium ion battery), the reaction of the negative electrode-aluminum battery was: Al3e +40H (-) = Al40H (-). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical expression of the reaction between iron and oxygen was: Iron + oxygen $\stack rel {ignite}{→}$iron oxide-iron. During the reaction process, iron (iron) burned violently in oxygen (O <2>), and sparks flew everywhere. After the burning stopped, a dark brown solid could be seen in the water at the bottom of the bottle. This dark brown solid was the iron oxide-iron dioxide (FeO) produced by the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

铝离子(Al³⁺)与氢氧化钾(KOH)反应分以下情况: 1. 当氢氧化钾少量时: - 化学方程式为:\(AlCl_{3}+3KOH = Al(OH)_{3}\downarrow+3KCl\)(以氯化铝为例,铝离子在溶液中,这里假设为氯化铝溶液),离子方程式为\(Al^{3 + }+3OH^{-}=Al(OH)_{3}\downarrow\)。 2. 当氢氧化钾过量时: - 首先发生\(AlCl_{3}+3KOH = Al(OH)_{3}\downarrow+3KCl\),然后生成的氢氧化铝继续与氢氧化钾反应,化学方程式为\(Al(OH)_{3}+KOH = KAlO_{2}+2H_{2}O\),总反应方程式为\(AlCl_{3}+4KOH = KAlO_{2}+3KCl + 2H_{2}O\),离子方程式为\(Al^{3 + }+4OH^{-}=AlO_{2}^{-}+2H_{2}O\)。 <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>
