Comparing the difficulty of the reaction between two substances and one substance
The difficulty and speed of chemical reactions between substances always followed the law of the greatest difference in the same property. That was, the greater the difference in a property between two substances, the more intense the reaction, the faster the reaction rate, and the easier the reaction to carry out. The more stable the compound formed, the smaller the difference in the same property, the slower the reaction, or even no reaction.
In addition, any reaction between substances would always be carried out in the direction of generating stable substances as much as possible from unstable substances. In the process of bond breaking, the bond with small bond energy would always break and transform into a bond with large bond energy. For example, in the reaction 3Cl2 + 8NH3 = 6NH4Cl2 +N2, Cl2 could not exist stably in nature, while N2 was a stable substance in nature, so the reaction proceeded in the direction of forming the stable substance N2. In the reaction SiO2 + 4HF = SiF4 + 2H2O, the bond energy of Si - O
Reaction phenomenon of the reaction between the two substances
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>
Are there any dissolvable substances in the reaction products?
Since you didn't provide the specific reaction content, it is impossible to determine whether the reaction product has any dissolvable substances. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Will there be thick smoke after the reaction of substances?
Thick smoke may be produced after the reaction of substances. For example, when carbon dioxide and carbon dioxide react, the carbon dioxide will be reduced to carbon, which will produce black smoke (carbon black). The reaction equation is [2MG + CO2 = 2Magnesia + C]. For example, a chemical plant in Rockdale County, George, USA, produced a large amount of smoke when it caught fire; The underground pipeline in Lianyungang, Jiangsu Province exploded and sprayed a large amount of black liquid and thick smoke; The fire scene caused by the firecrackers stored in a household in Shangqiu, Jinan, was also filled with thick smoke. The thick smoke may be produced by the chemical reaction of substances to form solid small particles, which were suspended in the air to form thick smoke. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The structure of the substance in which the iodoform reaction occurs
The material structure of the iodoform reaction has the following characteristics: Aldol and ketone containing the structure of CH3CO-can react with a halo in an acidic solution, and when the halo is iodoform, it is the iodoform reaction. In addition, a similar reaction can occur between alcohol and secondary alcohol containing this structure. The key factors affecting the iodoform reaction were the reaction activity of the carbonyl-H and the influence of steric hindrance. From the reaction mechanism, as the number of carbon atoms of the keto increased, the water dissolution decreased, and the reaction activity to generate enol negative ions decreased, and the degree of iodoform reaction gradually decreased. In the process of alpha-cleavage of triiodo-methylethone under the effect of base, the carbon atom of the carbonyl-group would be transformed from sp2 hybrids to sp3 hybrids. When the steric hindrance increased, the addition of- Oh to the carbonyl-group was difficult to carry out, which may cause the reaction to fail. For example, 2,6 -dimethylethyl-acetoxone could not see the formation of iodoform. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The conversion rate of the same reaction expressed by different substances
If there was more than one reagent, the conversion rate calculated according to different reagents might be different, but they all reflected the same objective fact, so it was possible to calculate the conversion rate according to any reagent. The conversion rate referred to the percentage or fraction of a certain reagent that was converted. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The difficulty of the substitution reaction of the aromatic ring is different
When the aromatic ring already had a substitution group, whether it was easy to introduce a new group and which position to enter was mainly determined by the nature of the original substitution group. Substituents on the aromatic ring can be divided into ortho-position, para-position and meta-position. The ortho-and para-positioning groups could allow new groups to enter the ortho-and para-positions of the group. These groups had unshared electron pairs with the atoms connected to the aromatic ring (except for R and Ph), which could be hyper-Conjugated with the aromatic ring, increasing the density of the electron cloud on the aromatic ring, making it easier for new positioning groups to enter the ortho-and para-positions of the group. The meta-locator was also known as the second type of locator, which could allow new groups to enter its meta-position. The atoms directly connected to the aromatic ring were generally either unsaturated (the other end of the heavy bond was an element with a higher electron negativity) or positively charged (there were exceptions), which could reduce the density of the electron cloud on the aromatic ring and make the aromatic ring passive. The electropathic substitution reaction was less active than that of the aromatic ring, and the reaction speed was slower than that of the aromatic ring. Meta-positioning groups (except for those with positive charges) were composed of atoms with high electron negativity and contained an unsaturated bond. They could be bonded to the aromatic ring, reducing the electron cloud density of the aromatic ring. Aromatic compounds were aromatic, so they were not easy to undergo addition reactions, but easy to undergo substitution reactions. However, the nature of the existing substitutes on the aromatic ring would affect the difficulty of the substitution reaction of the aromatic ring and the position of the new group. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The reaction between the amount of hydrogen sulfuric acid and the amount of substances such as soda
When the amount of substances such as the reaction of the hydrogen sulfuric acid (<anno data-annotation-id ="cd000004 - 4c04 - 4c00-a110-a11111111004"> NHSO4 </anno>) and the like react, the reaction equation is: <anno data-annotation-id ="3cd000 - 4c00 - 4c00-a11111100000"> NHSO4 + NH3 </anno>="aHSO4 + NH2 + O </anno>. During the reaction process, the hydrogen ion in the hydrogen sulfuric acid first reacted with the lithium hydrogen. Since the amount of the two substances was equal, the lithium ion did not participate in the reaction, forming the hydrogen sulfuric acid and the lithium hydrogen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
