When the solution was added to the solution, the first reaction would be between the solution and the water. The solution would then dissolve into a bright ball, which would then swim around on the surface of the liquid and make a squeaking sound. At the same time, it formed a mixture of the two, which then reacted with iron chlorideto form a reddish brown floccule deposit of iron dioxide. The chemical equation of the reaction is: 2Na +2H ^O = 2NaOx + H ^, FeClCl2 + 3NaOx = FeCl2 + 3NaOx +3NaCl2. Read more exciting novels for free
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>
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>
It was very difficult for the permethlene to react with the silver nitrates, and there was almost no obvious reaction. Because the reaction of the silver dimmer with the alcohol solution of silver nitrates was more difficult, it was more difficult to decompose the chloride-ester in water, and the intermediate product of the reaction, CH2 =CH·, was difficult to form, which was more difficult to react with silver nitrates than other halaloids. <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>

The reaction between red phosphorus and Cl2 would result in two reactions. The first reaction is the reaction of red phosphorus with Cl2 to form phosphorous tri-(2P +3Cl2) [2PCl3], and the phosphorus trichosphate was a colorless liquid; the phosphorus trichosphate then reacted with the Cl2 to form phosphorus pentachloride (<br><br>"<br>" 2PCl3 ", and the phosphorus trichosphate was a colorless liquid; the phosphorus trichosphate then reacted with the Cl2 to form phosphorus pentachloride (<br>" PCl3 + Cl2 "<br>" stacking " Phosphorous pentachlorides was a white solid. During the reaction process, the white solid particles of phosphorus pentachlorinate formed smoke, and the colorless liquid droplets of phosphorus tricolor formed fog, so the reaction phenomenon was white smoke. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
1. The combination of the hydrogen ion and the sodium-phenate to form the following: <C6H5O ^ -+H^+= C6H50H> 2. The color reaction of the reagent was: [(Fe^{3 +}+6C6H50H →(FeC6H5- O) 6)^{3 -}+6H^+]. Because it was a solution of iron dioxide, there were both iron ions and hydrogen ions, and the reaction between the two reacted to the above equation. <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>
1. * * Reaction equation and analysis of material properties ** - The composition of the water was complex. It contained Cl2, Cl2, and HClO. When the solution of Na2CO3 was mixed with water, the first reaction was: Cl2 + 2Na2CO3 + H2O = NaClO + NaClO +2NaHCO3. - Because of the participation of the Cl2 in the reaction, the yellowish-green color of the Cl2 water would gradually fade. - Gas was generated during the reaction because of the formation of CO2 (When the amount of Cl-water was excessive, the subsequent formation of Cl-and-NaHCO3 reacted with each other), so bubbles were observed. 2. * * Analysis of the change in the acidic and acidic properties of the solution ** - The solution of soda ash was basic. As the water was added, the reaction formed substances such as NaClO, NaHCO3, and so on. The basicity of the solution gradually weakened. - When there is an excess of Cl-water, the solution will eventually become acidic due to the large amount of Cl-water. 3. * * Impact analysis of hypochloric acid ** - Hypochloric acid has strong oxidisation and bleachability, but in this reaction system, the main reaction phenomenon is still determined by the reaction between Cl2 and Na2CO3 and the subsequent reaction between Cl2 and Na2HCO3. The effect of hypochloric acid is not obvious on the phenomenon, but mainly on the chemical properties of the solution. For example, it will produce an oxidisation effect on some reducing substances in the solution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
