If it was an ordinary car tire with normal tire pressure, it would cause serious harm to the human body and even endanger life. Because the car itself was heavy, the tire would exert a large pressure on the contact object when it came into contact with the ground under normal tire pressure. If it was an ultra-low-pressure tire (a low-pressure tire invented in the 1950s), it could maintain a low pressure state all the time. The wide tire could spread the weight of the vehicle over a large area. After testing, each point on the tire only applied two kilograms of force, so even if it ran over a person, the person might not be injured. However, this type of tire was very slow, with a top speed of no more than 15 kilometers per hour. It was mainly used in the oil exploration industry in some soft terrain areas such as Alaskan and Canada. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction equation is: 2NaHSO2 + 2CH CH2Ox = Na SO2 +H SO2 + 2CH CH2Ox. The phenomenon of this reaction was not mentioned in the information provided, 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>
The reaction between the acid and the acid would result in the formation of a sulfuric acid deposit. The reaction equation was Na Chi SiOx +2HNOOx == H Chi SiOx +2NaNOOx, and the reaction phenomenon was the formation of a white deposit. In this reaction, the sulfuric acid did not show any oxidisation, but only showed its acidic nature. This was because the silicon in the silica was already in the highest state, and the acidic nature of the sulfuric acid was stronger than that of the sulfuric acid, which was in line with the principle of making a weak acid from a strong acid. <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>
Aluminiothermic reaction was a kind of oxide-reduction reaction between aluminum and metal or non-metal compounds at high temperatures. Aluminiothermic reaction was an exhaling reaction, and its heat release was very large, usually enough to heat the product above the melting point, and the reaction could generally occur locally and be self-sustaining. This characteristic also reflected the energy-saving characteristics of the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Rearrangement reaction refers to the migration of certain atoms or groups in the molecules of organic compounds under certain reaction conditions, resulting in the reorganization of the molecular structure. For example, the Beckmann Rearrangement Reaction was a reaction in which ketoximes were rearranged into N-substituted diamides under the action of an acidic catalyst; the Cope Rearrangement Reaction was a (3,3)-sigma-shift rearranging reaction of 1,5 -diene; the Hofmann-Martius Rearrangement Reaction was a reaction in which N-alkylated aromatic compounds were rearranged to the corresponding o-/p-alkylated aromatic compounds under the action of acid catalyst; the Curtius Rearrangement Reaction was a type of nuclopathic rearrangements. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Esterification reaction was a irreversible reaction, and it was very difficult to achieve a complete reaction. In the esterfication reaction, the ester could be synthesized from the mixture of ether and alcohol. At the same time, the ester could also be decomposed into ether and alcohol by reacting with water. The direction of the reaction depended largely on the content of various substances in the reaction environment. When the content of one of the substances on the left side of the equation (such as vinegar and alcohol) was very high, the reaction would tend to form an ester, but it was still difficult to achieve a complete reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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>
The subjective reaction was not a mirror reaction. From the perspective of cognition, mirror reaction was a kind of objective reflection like looking in a mirror. This kind of reflection was like a mirror. Whatever the object outside the mirror was, the image in the mirror was the same. It did not change the object itself. It could only reflect the surface phenomenon of things, but could not reflect the essential laws of things. The subjective response contained two meanings. One was that people could actively understand the objective world, and the other was that they could actively transform the objective world under the guidance of their understanding. In the process of subjective reaction, people did not reflect the external world passively, but actively and actively. They could recognize and reflect the essence and laws of things in the practice of changing the object. This was fundamentally different from the mirror reaction that only reflected the surface of things. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The biuret reaction can be used to determine the quality or quantity of the protein. Biuret reagent could react with protein and form a purple complex in an acidic solution. The color was proportional to the concentration of the protein. Therefore, the existence of the protein could be detected by this reaction, and it could also be measured. However, biuret reagents could not be used to detect dipeptides because the reaction required the test substance to have at least two peptidic bonds. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
