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>

Under the high temperature smelting conditions, the matte-making reaction can be expressed as: (FeS)+(Cu2O)=(FeO)+(Cu2S), the reaction's Gibbs free energy change is? G0 = -144750+13.05T (J), and the equilibrium constant lgK of the reaction at 1250 ° C is 9.86, indicating that the reaction is rapidly moving to the right at the smelting temperature. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The main reaction of tempering steel was to let carbon and oxygen react to form carbon dioxide, thereby reducing the carbon content. The chemical equation of the reaction was: C + O <2>= ignition <2>= CO. The principle was that the main difference between pig iron and steel was the carbon content. The carbon content of steel was low, and the carbon in pig iron was reduced through this reaction to refine steel. At the same time, the iron-making reaction, Fe2 O2 + 3CO2 = 3CO2 + 2Fe2, was also a process that precluded the steel-making reaction, because steel-making was carried out with pig iron as the raw material.
制取乙醇的方法有多种,以下为您提供其中一种两步制取乙醇的化学方程式: 1. 粮食等含淀粉物质先转化为葡萄糖:\((C_{6}H_{10}O_{5})n + nH_{2}O \stackrel{酶}{→} nC_{6}H_{12}O_{6}\)。 2. 葡萄糖经发酵作用再转化为酒精:\(C_{6}H_{12}O_{6} \stackrel{酶}{→}2C_{2}H_{5}OH + 2CO_{2}\uparrow\)。 另外,也可以通过乙烯来制取乙醇,其两步反应如下: 1. 乙醇在浓硫酸作用下加热至170°C制得乙烯:\(C_{2}H_{5}OH \stackrel{浓H_{2}SO_{4},170°C}{→} CH_{2}=CH_{2}+H_{2}O\)。 2. 乙烯与溴单质发生加成反应后再反应得到乙醇(中间反应产物进一步反应的过程未详细给出,仅展示整体思路):\(CH_{2}=CH_{2}+Br_{2} \longrightarrow CH_{2}BrCH_{2}Br\)(后续反应未详细列出完整步骤以得到乙醇)。 还有乙烯直接水化法,分两步进行,第一步是乙烯与醋酸汞等汞盐在水 - 四氢呋喃溶液中生成有机汞化合物,而后用硼氢化钠还原,整体反应为:\(CH_{2}═CH_{2}+H─OH \stackrel{催化剂}{→}C_{2}H_{5}OH\)。 <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 term " negative potential " refers to the change in the negative potential caused by the flow of a negative current. During the process of the polar reduction, a reduction reaction would occur at the interface. This was because the polar reduction would cause the potential of the metal to shift negatively. When the equilibrium potential of the metal's oxido-reduction reaction was reached, the corrosion of the metal would be inhibited. This process was based on the principle of the polar reduction in electrochemistry, and the polar reaction in the polar reduction process was the reduction reaction. Therefore, the reduction reaction would be accelerated by the negative pole. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
This statement was not accurate. In electrochemistry, the negative pole was the one where the reduction reaction took place. In many electrochemistry processes, the negative pole was involved in the reaction. For example, in an electrolyser, a reduction reaction occurs at the negative pole, and the positive ions in the solution are reduced by electrons at the negative pole. For example, in the case of copper sulfuric acid solution, a pure copper sheet was used as the negative pole, and the copper ions in the bath obtained electrons on the negative pole to separate copper. The reaction was Cu2 + 2e = Copper, and the negative pole was involved in the reaction process. During the battery discharge process, the negative pole was the positive pole, which was also involved in the reaction. After the electrons flowed into the positive pole, the material on the positive pole (negative pole) that easily obtained electrons first obtained electrons to undergo a reduction reaction. However, in some special cases, the negative pole may act as an interface for electron transfer, but generally speaking, the negative pole was usually involved in the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
