When the reaction of the two reagents, namely, C10H10Na and FeCl10Na, takes place, a double-water reaction takes place. 1. ** Analyzing the reaction process ** - The equation of the reaction is: C6H5ONa + H2O2 = C6H50H + Na2O3 = C6H50H = Na2O3 = Na2O3 = Na2 - Ferric acid is acidic when it is dissolved in water, and the equation is: [FeCl3 + 3H2O'rightlefttharpoons FeCl3 + 3Cl2]. - When the mixture of the two substances was mixed, the reaction between the two substances would cause the equilibrium between the two substances to shift to the right, and eventually, the reaction would be complete. 2. ** Write the reaction equation ** - The general reaction equation is: [3C6H5ONa + FeCl3 + 3H2O = 3C6H50H + FeCl3]. Therefore, the chemical equation of the reaction of the addition of iron chloride-Na-phenate is [3C6H5ONa + FeCl3 + 3H2O = 3C6H50H + FeCl3][downarrow +3NaCl3]. Read more exciting novels for free
There was no reaction between the two. This was because the reaction between the two was a metathesis reaction, but the metathesis reaction required at least one of the two new salt to be a preciptate, and there was no preciptate formed in the reaction. Moreover, both of them contained the element of sulfur, so they could not exchange components in the reaction, so there would be no reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between FeClCl2 and alcohol (C2H20H) under heating was more complicated, and it was generally believed that alcohol would be oxided by FeCl2. The reaction equation was: 6C H Oh + 4FeCl → 4Fe6CHCHO +12HQ +3H O (This reaction was only a possible reaction, and there may be many side reactions in the actual reaction). Phenomenon: The color of the solution may change because the iron chloride-based solution itself is brownish-yellow. Due to the formation of new substances during the reaction, the color may become lighter or other color changes may occur. If iron is formed, black solid substances may appear (but if the amount of iron formed is small, it may not be easy to observe). At the same time, there may be a pungent smell (because of the formation of substances such as Zhang). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
There was no chemical reaction between the two. However, when the salt was added to the calcium dioxide, the dissolution of the calcium dioxide would increase. This was because of the salt effect. In the presence of a strong solute (such as calcium dioxide), the dissolution of some solute (such as calcium dioxide) would be greater than in water. This phenomenon of increasing the dissolution of the precipitations due to the addition of a strong solute was called the salt effect. It had to be distinguished from the same ion effect, which would reduce the dissolution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between lead sulfuric acid and sulfuric acid could not produce precipitations, gases, and water, so the two could not react. There was no reaction equation or reaction phenomenon. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between the two substances would produce the compound, K [Fe(c o]], and the reaction would turn the solution green. This was because the complex formed by the formation of the iron and the iron were green in the solution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction conditions for the reaction of iron and Cl2 to form FeCl3 were as follows: - Under ignition, iron and Cl2 react to form FeCl3. The reaction equation is [2Fe3 + 3Cl2]{=[2Fe3 + 3Cl2]} 2FeCl_{3}\)。 - Under heating conditions, the dry iron combined with the Cl2 to form FeCl3. - Iron would undergo a passive reaction in the dry Cl2 at room temperature, and it would react in the humid Cl2. The reaction pathway and products would change with the conditions. When heated, the main reaction would be a chemical reaction to produce iron chloride-like iron. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Ferric acid (FeCl2) solid does not react with sulfuric acid (HQ). In chemistry, there was no chemical reaction when iron chloride-sulfuric acid was mixed, because they existed in the form of ions in the solution (Fe3, Cl3, H3, Cl3). These ions did not produce new substances, which did not meet the conditions for chemical reactions (forming new substances such as precipitations, gases, or water). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
If the two did not react, the reaction equation could not be written. carbon dioxide (CO2) was a non-metallic oxide-like substance, while Cl2 was a non-metallic elemental substance. A substitution reaction occurred between the compound and the elemental substance. However, this kind of reaction required the compound to be a dissolved metal compound or acid, while CO2 was a non-metal compound, which did not meet the conditions, so the two did not react. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
硼砂中的\(Na_{2}B_{4}O_{7}\)在酸溶液中反应的离子方程式为:\(B_{4}O_{7}^{2 -}+2H^{+}+5H_{2}O = 4H_{3}BO_{3}\)。其书写思路如下: 1. 首先确定反应物和生成物,硼砂\(Na_{2}B_{4}O_{7}\)与酸反应生成硼酸\(H_{3}BO_{3}\)。 2. 然后根据物质的组成写出其离子形式,\(Na_{2}B_{4}O_{7}\)可拆分为\(B_{4}O_{7}^{2 -}\),酸中的氢离子\(H^{+}\)参与反应,反应后生成\(H_{3}BO_{3}\)(硼酸为弱酸,在离子方程式中写分子式)。 3. 根据电荷守恒和原子守恒配平离子方程式,得到\(B_{4}O_{7}^{2 -}+2H^{+}+5H_{2}O = 4H_{3}BO_{3}\)。 <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 reaction equation of KManganate and Manganic Sulphate is: 2KManganate +3Manganic Sulphate +2H <2> O = 5Manganic Sulphate +2H <2> Sulphate or 3Manganic Sulphate +2KManganic Sulphate +2H <2> O = 5H <2> Manganic Sulphate + K <2> Sulphate +2H <2> Sulphate. From the reaction equation, it was a neutral reaction. In the reaction, the Mn element in the potassium Permanganate was +7, the Mn element in the Manganic Sulphate was +2, and the Mn element in the Manganic Dioxid formed after the reaction was +4. During the reaction process, the different valences of the Mn element underwent an oxidoreduction reaction, causing the valency to return to +4. In terms of phenomena, the reaction would produce Manganese Dioxid, and the color of the solution might change or solid matter might be formed (Manganese Dioxid was a black solid). The specific phenomenon might also be affected by the reaction conditions (such as solution concentration, temperature, etc.). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
