Mind Map of Material Reaction, Volume One, Volume One
The first volume of the mind map of the material reaction mainly covered the following aspects: ** I. Reaction related to the composition and properties of matter ** 1. ** The three states of matter and their mutual transformation ** - The transformation between solid, liquid, and gas involved energy changes and other factors. For example, a solid that absorbs heat can be transformed into a liquid (melting), and a liquid that absorbs heat can be transformed into a gas (vaporizing). Conversely, a gas that emits heat can be transformed into a liquid (vaporizing), and a liquid that emits heat can be transformed into a solid (solidifying). During the conversion process, there would be dipping, dissolving, and settling. For example, salt dissolving in water was a dissolving phenomenon. When the solution reached saturation, adding solute might cause a settling phenomenon. 2. ** Reaction between pure substances and impurities ** - Pure substances were composed of a single substance. To judge a pure substance, one needed to rely on its fixed composition and properties. The presence of impurities would affect the purity of the substance. The methods to separate impurities were filtering (suitable for a mixture of solid and liquid, and the solid was not dissolved in the liquid, such as separating sand and water), and retorting (suitable for separating a mixture of liquids with different boiling points, such as separating alcohol and water). For example, tap water contained impurities, and purified water could be obtained through methods such as retorting. 3. ** Reaction of chemical elements and compounds ** - Elements were the basic components of substances, and compounds were pure substances composed of different elements. For example, oxygen (made up of oxygen) could react with hydrogen (made up of hydrogen) to form water (a compound made up of hydrogen and oxygen), and carbon dioxide (made up of carbon and oxygen) could participate in plants 'photosynthesis and other reactions. ** 2. Reaction related to chemical changes and energy ** 1. ** Basic Concepts of the Reaction ** - In a chemical reaction, a reagent was transformed into a product. The chemical reaction equation was used to express the material change relationship of the reaction. For example, the reaction between iron and sulfur to form iron dioxide was as follows: 2. ** Reaction Rate and Reaction Condition ** - The factors that affected the rate of chemical reactions included temperature, concentration, and so on. When the temperature rises, the reaction rate is usually accelerated. For example, when oxygen is produced in the laboratory, the reaction rate of heating the decomposition of potassium pernate is faster than that at room temperature. Increasing the concentration of the reagent will also speed up the reaction rate. For example, within a certain range, increasing the concentration of sulfuric acid will increase the reaction rate of carbon dioxide generated by the reaction with marble. 3. ** Energy and chemical reaction ** - A chemical reaction was accompanied by a change in energy, and there were both heat releasing and heat absorbing reactions. The combustion reaction was a common heat release reaction, such as charcoal burning to release heat, while some reactions, such as the high temperature decomposition of calcium dioxide, were heat absorption reactions, absorbing heat during the reaction. ** 3. Air and carbon monoxide-related reaction ** 1. ** Reaction related to the composition and properties of air ** - In the air, nitrogen accounted for about 78%, oxygen accounted for about 21%, and a small amount of carbon dioxide and rare gases. The oxygen had the ability to support combustion and could support the combustion of many substances. For example, iron burned in oxygen to form iron tritium. The chemical properties of nitrogen were relatively stable and could be used as a protective gas. 2. ** Reaction between moisture in the air and weather conditions ** - The relative humidity was related to the amount of water vapor in the air. When the water vapor reached saturation, the temperature would drop, and dew would form. This process involved physical processes such as the phase change of water vapor, but it was also related to the environmental conditions of some chemical reactions. For example, iron rusting required the presence of water vapor and oxygen in the air at the same time. Read more exciting novels for free

The Chen Family of the Court Officials
In the lineage of the Chen family in Liupu, Maoshan Village, Duwei Town, Xianyou County, there was a record of the Chen family being an official. It mentioned the illustrious family background of "three generations, five scholars and five doctors", but did not explicitly mention the direct connection between the Chaofeng doctor and the Chen family. In the Chen family of Wuchuan Courtyard and Si 'an, the ancestor of the family, Duke Sanshan, was a scholar of the Northern Song Dynasty. He was appointed as the governor of Gaoliang Prefecture and the governor of Gaozhou Prefecture. His surname was Chen and his surname was Huang. He was the founder of the Chen family of Wuchuan Courtyard and Si' an. He had the official position of the fifth rank of the court officer in the official system of the Northern Song Dynasty. He mainly presided over the emperor's sacrifice and religious ceremonies. He had many achievements in the local area, such as educating the people first, creating schools and rejuvenating the people, etc. He later resigned and lived in Bodao Township, Wuchuan County, Paiyan Courtyard and Si 'an. Therefore, there might be people who served as court officials in the Chen family in different regions, and they had different meanings and contributions to the development of their respective families and local history.

Elementary school basketball passing teaching reflection short version
There are many points worth reflecting on in the teaching of basketball passing in primary schools. First of all, he had to pay attention to the explanation of the basic movements and make clear the key and difficult points, such as the key movements of kicking, stretching, flipping, and poking when passing the ball and stretching the arm when catching the ball, as well as the difficulties of stretching, coordination, and strength. However, there might be a situation where students did not pay enough attention to the basic movements in the teaching, because they were easily attracted by the wonderful passes in the basketball game on TV and despised the basics. Secondly, teaching should follow the principle of gradual progress. Students were both unfamiliar and familiar with basketball. They had less time to practice, and female students were even less involved. Therefore, the teaching should be carried out step by step from imitation practice to close-range passing and catching, and then to long-distance passing and catching. However, in actual teaching, it might not be accurate enough to grasp the progress, causing some students to be unable to keep up with the pace. Moreover, he should predict and give hints to students who might make mistakes in their actions. However, in actual teaching, although some precautions were taken, there might still be situations where it was not fully covered, causing some students to have difficulty correcting their mistakes. These were all areas that needed to be improved in the subsequent teaching. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What kind of mathematical symbol is a positive u and an inverse u?
In mathematics, a positive U (U) represents A union. It is a set formed by combining all the elements of two sets A and B. It is recorded as A, B, and read as A and B. Formally, the union of A and B is a set with all the elements of A and all the elements of B, and no other elements. It is expressed in symbolic language as A, B = {x| The inverse U (Empyrean) represents the intersection. Let A and B be two sets. The set composed of all the elements belonging to set A and set B is called the intersection of set A and set B, which is recorded as A Empyrean B. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Funan Yuquan kindergarten registration in 2020
In 2020, Yuquan kindergarten recruited new students independently according to the spirit of the Notice of Fuyang City Education Bureau on Seriously Doing a Good Job in the Work of Entering the City's Nurseries in 2020, combined with its own conditions and class size. In August, the children of the right age in Xiangyuan Park City received a notice from the sales department that they could register for a small class at Yuquan kindergarten. They prepared all the materials and passed the review successfully. However, due to the renovation of the park city branch, the school was postponed. At the end of October, they could not enter the school because they did not get the notice. During this period, no one called to tell them that they needed to get the notice to go to school. In addition, pre-school education was not compulsory education. At that time, Urban area public kindergarten in Funan County did not carry out school districts, and there were many districts around Yuquan kindergarten, so there was a lot of pressure to recruit students, and the degree was tight. According to the kindergarten class quota setting standards (small class no more than 25 people, middle class no more than 30 people, big class no more than 35 people), the class quota was full, there was no vacant degree, no longer recruiting transfer students. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Are state-owned hospitals considered social organizations? Why aren't they organized?
A state-owned hospital was not considered a social organization. A state-owned hospital was a medical institution run by a state-owned enterprise, and a state-owned enterprise was usually a form of establishment. There was a fundamental difference between a hospital under its system and a social organization. As for the establishment of state-owned hospitals, some state-owned hospitals had their own establishment. However, with the reform of state-owned hospitals, state-owned hospitals may face restructuring and other situations. During the restructuring process, there may be adjustments to the establishment. For example, after the reform is completed through transferring to the local government, it may be incorporated into the establishment system of local public institutions. However, there are also situations such as losing the original establishment after transferring to private enterprises. It could not be said that state-owned hospitals did not have any staff. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
