Acid, base, and salt can all be vaporized when they are dissolved in water or in a molten state. After the salt was dissolved in water, the weak radical ions from the salt would combine with the hydrogen or hydrogen radical ions from the water, destroying the water's equilibrium of ions and thus forming a weak solute. Only salt could be subjected to the process of water decomposition, and not all salt could be subjected to water decomposition. It depended on whether it contained weak acid or weak base radical ions (strong acid or strong base salt could not be subjected to water decomposition). Ionization was the prerequisite for the decomposition reaction. Only when the ions were produced in the solution could the decomposition of the salt occur. Therefore, salt had the phenomenon of dissolution, and some salt had the phenomenon of dehydration. Read more exciting novels for free
The equation for the reaction between aluminum ions and carbonates is: 2Al3 + +3CO32- +3H2O === 2Al3 + 3CO2. The analysis of the reaction phenomenon was as follows: When aluminum ions (Al3 +) came into contact with carbon dioxide ions (CO32-), theoretically, they would form aluminum dioxide, but aluminum dioxide was a weak acid and weak base salt, and it was easy to decompose in an aquatic solution. In the process of digestion, aluminum ions combined with the hydrogen ions in the water to form aluminum trioxides. At the same time, the carbon dioxide ions came into contact with the hydrogen ions. As the carbon dioxide was unstable and volatile, it decomposed to produce carbon dioxide gas. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
There is no chemical reaction between NaCl2 and magnesiumcarbonate2. In chemistry, the conditions for metathesis reactions to occur were the formation of precipitations, gases, or water. After mixing the two, the conditions for the metathesis reaction were not met, so there was no reaction, no reaction equation, and no reaction phenomenon. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
There is no chemical reaction between the two of them. In terms of chemical principles, the conditions for the metathesis reaction to occur were the formation of precipitations, gases, or water. The mixture of the two did not meet the conditions for the metathesis reaction to occur, so there would be no reaction. Therefore, there was no reaction equation, reaction phenomenon, and phenomenon analysis. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction of the two reagents would produce a light green deposit (nickelous carbonite) and then a solution of the two reagents. However, if the test tube was shaken, the deposit would dissolve, regardless of the amount of the reagent. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The chemical equation of the reaction between hydrogen and Cl2 was H ^+ Cl2 = 2HQ (Condition: Illumination or ignition). [Phenomenon: When hydrogen and Cl2 react, if it burns quietly, it will emit a pale flame, and there will be white fog at the mouth of the gas collector. If hydrogen and Cl2 are mixed and illuminated, it will explode.] <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction equation of the reaction between the two substances was: CH2O +Nahs→ HO-SO2-CH2- ONa(*)→ NaO-SO2-CH2- Oh (the final product was the sodium-methylethylmethanate). The reaction process was first to attack the carbon atom with the lone pair electron on the S atom in the ion, forming the intermediate (*). Since the acid of the sulfuric acid was much stronger than the alcohol,(*) quickly underwent a proton-transfer to obtain the final product. No information related to this reaction phenomenon was found. Unable to answer accurately. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between alcohol and iron dioxide forms an alcohol, CH3Hamster. The reaction equation is: C2H50H + Fe2O3 → CH3Hamster + Iron (unbalanced). The current reference materials did not mention the phenomenon of this reaction, so it was impossible to give an accurate answer. <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>
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>
