Reaction Formula of the Cooler and Water
Different coolants react differently with water: - The solidifying temperature of the formed water solution is lower than 0 ° C. The chemical equation of the reaction with water is not mentioned. - The chemical equation for the reaction between fluorine and water is: 2F <2>+2H <2> O = 4HF + O <2>. - Halocarbon and carbon-hydrogen condensants were difficult to dissolve in water. There was no mention of the chemical equation for the reaction with water, but water would undergo a phenomenon of dehydration after dissolving the condensants, forming acidic substances. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to write the chemical formula of the reaction of hydrogen carbonate-water
The reaction between the two was a physical one. There was no chemical equation. The chemical properties of the metathesis reaction between the compounds were that it only reacted with acid, base, and salt. It did not react with non-metal compounds (water was a non-metal compound). However, the hydrogen carbonate-like ion would undergo a water decomposition reaction, and the chemical equation was: [HCO3]^{-}+H_{2}O [Rightleftharpoons H_{2} CO3}+ SH ^{-}]. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Alum in Water
In cold water, the dissolution of the aluminum was limited. In warm water, due to the decomposition, the aluminum would be separated and form aluminum trioxides. The aluminum trioxides had a strong absorption effect (because it was charged), which would absorb impurities in the water such as iron ions to form larger molecular clusters. The molecular clusters would become yellow, and the molecular clusters would become larger and larger. Finally, they would sink to the bottom, and the water would become clean. In addition, if you add aluminum to turbid natural water, stir and dissolve it, and then let it stand, it will produce settling. This is because the colloid substance formed by aluminum dissolving in water has an absorption effect on impurities, causing impurities to settle. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is water absorption a chemical reaction or a physical reaction
Water absorption was usually a physical property that was reflected in physical changes, but some also involved chemical changes. For example, the solid state of soda ash had a strong moisture absorption. It absorbed the surrounding water vapor and dissolved in the absorbed water, forming a concentrated solution of soda ash. This process was a physical change. The concentrated sulfuric acid could absorb the water vapor in the air around it to form a series of water compounds. On the other hand, the concentrated sulfuric acid dissolved in the absorbed water to make itself thinner, which also involved physical changes. However, the concentrated sulfuric acid absorbed the first water molecules in the copper sulfuric acid, which reflected the water absorption (physical property), and the removal of the remaining four water molecules reflected the dehydration (chemical property). The main component of the quicklime drying agent was lime, and its water absorption ability was achieved through a chemical reaction. This water absorption was irreversible. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the reaction conditions for the reaction of propene and Bromine water?
The electropathic addition reaction between propene and bromic water did not require any special reaction conditions. The reaction formula was: CH2 = CH-CH3 + Br2 → CH2Br-CHBr-CH3. Under illumination or with a free radical initiator, a free radical substitution reaction could occur: CH2 = CH-CH3 + Br2 → CH2 = CH-CH2Br2 (the main reaction). At the same time, a free radical addition reaction could also occur: CH2 = CH-CH3 + Br2 → CH2Br-CHBr-CH3. Under appropriate conditions, the reaction of propene and Bromine to form 1,3 -dibromopropan is usually carried out in an inactive solution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Bromine Gas and Water
The water contained Cl2, and since Cl2 was more oxidiser than Bromine, Bromine gas and Cl2 did not react. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction of toothpaste squeezing into water
The surface of toothpaste usually contains a surfacing agent. When the toothpaste is squeezed into water, the water molecules will form a thin layer on the surface of the toothpaste. This is a phenomenon of surface tension, which will cause the water droplets to form a spherical shape on the surface of the toothpaste instead of spreading out. Due to the effect of the surface active agent in the toothpaste, the force between the water droplets and the surface of the toothpaste would change, and the water droplets would float for a while. Moreover, there were chemical components in the toothpaste that would react with water to produce gas, pushing the small pieces of toothpaste to "swim" on the water surface. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Acetic Anhydryl with Water
The reaction between water and sulfuric acid is: (CH CO) 2 O + H 2 O → 2CH COON. This reaction is a process of ester decomposition. The ester bond (C=O) of the sulfuric acid was broken by water molecules to form sulfuric acid. The reaction was a irreversible reaction, and the reaction rate was affected by factors such as temperature, concentration, and catalyst. The reaction rate was slow at room temperature and needed a long time to reach equilibrium. The reaction rate would increase under high temperature and acidic conditions. The equilibrium constant (Keq) of the reaction was related to the temperature. Generally, the equilibrium constant increased as the temperature increased. This was because the difference in the thermal energy between the reaction and the product decreased at high temperatures, causing the reaction to shift more toward the product. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction Formula of Substitution Reaction for the addition reaction of organic substances
Additional reaction: - The addition reaction of ethene and Bromine: <<CH2 = CH2 + Br2> - The addition reaction of ethene and hydrogen bromidate was as follows: <CH2 = CH2> - Under certain conditions, addition reactions could also occur between ethene, hydrogen, and water. Since the chemical properties of ethyne (carbon-carbon triple bond) were similar to that of alkene (carbon-carbon double bond), similar addition reactions could also occur. - The aromatic ring can undergo an addition reaction with hydrogen (in the presence of a catalyst such as Ni). - Aldol groups can undergo a reduction reaction (addition reaction), such as: <anno data-annotation-id ="00000000 - 4c00 - 4c00 - 8c00 - 9c00 - 9c000b000000"> CH3CH20H </anno>. Substitution reaction: - The substitution reaction between methane and Cl2: CH4 + Cl2. - The substitution reaction of the aromatic ring: For example, the substitution reaction with the aromatic group using FeBr3 as a catalyst; the nitration reaction with the aromatic group using concentrated sulfuric acid under heating conditions (the hydrogen on the aromatic ring is replaced by the nitrogen group). - The substitution reaction of the halated carbon was as follows: <<CH3CH2Br2>+<NaBr2>>. - The substitution reaction of alcohol: <CH3CH20H>+<br>> longrightarrow <CH3CH2br>+<H2O>> - The ester's cleavage reaction (which can be seen as a substitution reaction):<CH3COOCH2CH3 + H2O> <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Toluene and Bromine Water with Iron
The solution was separated into layers. Bromine water was denser than toluene. Bromine water was in the lower layer. The upper layer was orange-red, and the lower layer was almost colorless. This was because toluene did not react with the bromine water, but it could extract the bromine in the bromine water. After the separation, the upper layer of the organic layer (the solution of the solute of the solute) reacted violently with a small amount of iron powder, producing reddish-brown vapor. After purification, a colorless oily liquid was obtained. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
