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.

Reaction Formula of Acetic Acid and Ester
The chemical equation for the reaction of sulfuric acid and alcohol to form ethvl was: CH COOx + C H Oh = CH COOx H + H O (The reaction condition was heating concentrated sulfuric acid, and the reaction was a irreversible reaction). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What's the reaction between Phtholic Anhydryl and Butanol?
Phtholic Anhydryl and Butanol were used as the catalyst to produce the ester reaction. The reaction was carried out in two steps. The first step was the ring-opening reaction between the aromatic acid and the Butanol to form the monoblast-ester of the Phtalate. This step was rapid and gave off a large heat. The second step was the ester reaction between the Butanol and the Carboxyl Group on the monoblast-ester of the Phtalate. This step was more difficult. It required a higher temperature and a water-carrying agent to remove the water produced. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction between Acetic Acid and Edible Oil
Acetic acid would react with cooking oil. From a chemical point of view, oil was a fatty acid ester. The reaction between vinegar and edible oil would produce a small amount of vinegar, but the amount was very small and could be ignored. After mixing a small amount of white vinegar and a few drops of edible oil, it will form an ointment. There will be oil on the surface of the dispersing system. After standing for about 1 minute, it will be clearly separated. The upper layer is mostly oil, and the lower layer is mostly water. Because the content of vinegar in edible vinegar is generally 3 - 5%, it has little dissolving effect on edible oil, and oil and water are not compatible. In addition, the chemical reaction between vinegar and animal or vegetable fats would change the taste. Moreover, from the perspective of chemical fermentation, the reaction between vinegar and fats may be related to the rancidity of the oil. Usually, vinegar bottles should not be used to contain edible oil to prevent pollution and rancidity. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Poly (Viny Acetic Ester) with Alcohol
Poly (vinyi) acetate-alcohol can react with methanoi. This reaction is called alcoholization (or ester exchange reaction). Poly (vinyi) acetate-alcohol can be produced by alcoholization of methanoi to remove the carbolic acid. In the industry, because the reaction temperature of solution synthesis was easy to control and the number of branches of the solution was small, the resulting PVP solution could be directly alcoholized to prepare PVP. Poly (vinyi) acetate-ester was dissolved in the presence of the alcohol, but the reaction product, Poly (vinyi) alcohol, was not dissolved in the presence of the alcohol. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Esterification product of acetic-acid and acetic-ester
The products of the fermentation reaction between the two were water and ether. The reaction equation is: <br><br> CH3COON + C2H50H <br> CH3COOC2H5 + H2O. This reaction was irreversible. During the reaction, the acidic group ($-COON $) combined with the alcoholic group ($-Oh$), removing a water atom to form the ester. <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>
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>
Reversible reaction between hydrogen and water
The reaction between hydrogen and water is irreversible, and the reaction equation is NH3 + H2O NH3·H2O. In this reaction, the majority of the dissolved hydrogen in water combined with the water to form a single water of hydrogen (NH3·H2O), and only a small portion of the single water of hydrogen would be ionised. Moreover, the reaction was irreversible. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
