le chatelier's principle class 11

The principle of bleachings was to make objects lose their color through the oxidisation properties of bleaches. Different types of bleaches had different principles. The principle of the bleaching-powder was that the bleaching-powder would produce hypochloric acid when it came into contact with water. The hypochloric acid could catalyze the coloring matter, thus achieving the purpose of the bleaching-powder. The principle of hydrogen dioxide was that hydrogen dioxide was a strong oxidiser. It could destroy the " chromophore " inside the organic color substance and cause it to lose its original color. The principle of the absorption bleachings was that the substance had a large surface area, which could absorb the dye and make the substance fade. Other bleaches such as sulfur dioxide and ClO2 had similar principles. In general, bleaches change the color of objects or fade them through an oxidization reaction.

The primary principle of children's literature creation was to make children happy and inspired. Usually, children's literature would focus on describing children's daily lives and emotional experiences, and stimulate their curiosity and interest through stories and plots. In addition, the creation of children's literature would also take into account the children's age and cognitive level to ensure that the content was suitable for their growth and development.

The primary principle of children's literature creation was to protect children's physical and mental health. In the process of writing, one should try to avoid using negative emotional elements such as violence, horror, and hatred. At the same time, one should pay attention to the twists and turns of the plot, the suspense, and the concise and easy to understand language. In addition, in children's literature creation, attention should be paid to avoid portraying overly mature characters and to avoid imposing adult values on children.

The principle of isoniazid's anti-inflammatory effect was to suppress the synthesis of mycolic acid in the cell wall of the fungus, causing the bacteria to lose its acid resistance, repulsion, and reproductive ability. In addition, isoniazid can also interfere with the synthesis of DNA and DNA of M. tubers, thereby suppressing the growth and reproduction of M. tubers. It could also combine with the mitochondria of the fungus to interfere with the synthesis of DNA, further achieving the purpose of killing the fungus.

Chen Boda's principle of changing fate was to refrain from doing evil and to pursue good. He believed that the first step to changing fate was to distinguish between good and evil. Only by understanding good and evil could one distinguish between good and evil, thus abandoning evil and promoting good. Secondly, he advocated that all evil deeds would bring negative effects to people, so people should avoid doing any evil deeds and lay a good foundation to change their fate. At the same time, Chen Boda emphasized the pursuit of good deeds. He believed that people should actively do good deeds and make actions that were beneficial to society and others. Through continuous good deeds, people's fate would gradually change. In addition, he also mentioned that changing fate required perseverance. In general, Chen Baida believed that people could change their destiny by distinguishing good from evil, avoiding evil, doing good, and maintaining perseverance.

The principle of reducing bleaches was to make use of the reduction effect of the dye to fade. The color of organic matter was produced by the color groups contained in its molecules, and the color groups contained unsaturated bonds. The reducing bleaches release hydrogen atoms, causing the saturated bonds contained in the coloring base to become single bonds, and the organic matter would lose its color. This kind of bleacher can make the coloring in food decompose and fade through reduction.

The eye of a typhoon was a special area in the center of the typhoon. The formation principle was that the wind inside the typhoon rotated counterclockwise, causing the air in the center to rotate. The centrifugal force generated by the rotation and the wind force rotating toward the center balanced each other, resulting in a windless phenomenon within dozens of kilometers of the typhoon center. In addition, the air in the eye area of the typhoon sank and warmed up, causing the clouds to dissipate and the rain to disperse. The weather was clear.

There were many ways to prepare the bleachers. One of the common methods was to add Cl2 into water to form Cl2 and Cl3. This kind of bleachers used its strong oxidization ability to vaporize the "chromophore" inside the organic color substance, causing it to lose its original color. The other method was to prepare the bleachers by vaporizing salt water, which would produce both NaClO and NaOx. The content of the bleachers could vary depending on the preparation method, and was generally between 4-15%. In addition, the active ingredients in the bleachers were mainly the two main ingredients, namely, the hypochlorites and the chlorites. In general, the principle of the preparation of the bleachers was to use the strong oxidization of the bleachers to achieve the bleachability of the colored substances.

The construction principle of Xuankong Temple was to distribute the weight of the building on the supporting structure to achieve the effect of hanging on the cliff. Xuankong Temple used the principles of mechanics to insert flying beams as the foundation, relying on the rocks as the hidden support. The beams and columns were one body, and the corridors were connected to the left and right. The plank road that looked up at the sky was only supported by a few vertical and horizontal logs. The true center of gravity of Xuan Kong Temple was supported by the hard rock, using the principles of mechanics and the structure of the flying beam. In addition, the wood used for the flying beams of Xuankong Temple was the local specialty hemlock wood. It was soaked in tung oil before use to prevent corrosion and insects. These special architectural designs and materials allowed Xuan Kong Temple to remain standing for thousands of years and become one of the world's greatest architectural miracles.

The construction principle of Xuankong Temple was to use mechanical principles and rock support to distribute the weight of the building on the supporting structure to achieve the effect of hanging on the cliff. To be more specific, Xuankong Temple used a half-inserted flying beam as the foundation. With the support of the rock, the beam and column were one body, and the corridor was connected to the left and right, forming an entire wooden frame structure. In addition, Xuankong Temple chose a suitable cliff as the construction site to ensure that the cliff had sufficient height and straightness to ensure the stability and safety of the building when it was suspended. In general, the architectural principle of Xuankong Temple was to hang the building on the cliff, creating a unique and spectacular architectural form.
