Shanghai High School Chemistry and Biogeography
This combination of subjects had a certain advantage. In terms of learning difficulty, compared to some traditional science combinations, the learning pressure was relatively small. Chemistry and biology were closely related, and they could promote mutual understanding in the learning process. They might also have an advantage in terms of grading. From the perspective of the available majors, because there was no physics, it would limit the application of some science majors. The proportion of available majors was not very high, but there were still more choices. The subject of geography had the characteristics of both liberal arts and science. For this combination, it could increase the advantages of liberal arts. If the student was interested in chemistry and biology, had a certain learning ability in geography, and did not plan to apply for a major with high physics requirements, this combination was a good choice.

High School Chemistry 4 Reaction Devices
The common reaction devices in middle school chemistry included the following: 1. ** Test tube reaction device **: - Can be used at room temperature or under heating conditions. It could be used as a reaction vessel for a small amount of reagents at room temperature or when heated. It could also be used to dissolve a small amount of solid and collect a small amount of gas. It could also be used as a small gas generator. When heating, the outer wall must be dry. It cannot be suddenly heated and cooled. Generally, it must be evenly heated first before it can be concentrated. When heating solid, the mouth of the test tube should be slightly inclined downward, and the test tube cannot stand upright before it is cold. When heating liquid, the amount of liquid should generally not exceed 1/3 of the volume of the test tube, so that the test tube and the table form an angle of about 45°. The liquid in the test tube during the reaction should not exceed 1/2 of the volume of the test tube. The test tube clip should be clamped in the upper middle of the test tube (or the iron clip should be clamped 1/3 away from the test tube mouth). 2. ** Beaker reaction device **: - It could be used to dissolve solid substances, formulate solutions, dilute and concentrate solutions, and could also be used for reactions between large amounts of substances. When heated, the outer wall should be dry, and placed on the gauze to make it evenly heated. The amount of liquid added should generally not exceed 1/2 of the volume. 3. ** Flask reaction device **: - There were round-bottom flasks and flat-bottom flasks. Round-bottom flasks were generally used as reaction vessels under heating conditions. They could be used for reactions between large amounts of liquids, and could also be used as gas generators. The bottom of the round-bottom flask was relatively uniform in thickness and had no edges. It could be used for long-term strong heat. When heating, it should be placed on an earthworm net and could not be heated directly with a flame. Flat-bottomed flasks were used for gas generators without heating, and were also commonly used to assemble washing bottles. Due to the small bottom plane, the edges were sharp, and the stress was large, it was easy to explode when heated, so it was generally not used for reaction vessels under heating conditions. 4. ** Conical Flask Reaction Device **: - It is commonly used in reactions involving liquids and can be used to assemble gas generators. Usually, it needed to be indirectly heated with a cushion of gauze to make the heat uniform and prevent the instrument from cracking due to uneven heating. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What are the reactions of high school students in organic chemistry?
The reaction types in high school students 'organic chemistry included substitution reactions, addition reactions, and so on. A substitution reaction is a reaction in which certain atoms or atomic groups in an organic compound are replaced by other atoms or atomic groups. In middle school chemistry, substitution reactions included specific types such as substitution, fermentation, dehydration, nitration, and substitution. For example, alkyls, alkyls, aromatic compounds, alcohol, and acids can undergo substitution reactions with the simple substances of the halo. The nitration reactions of the aromatic compounds, alcohol, and alkyls can be carried out. Almost all of the aromatic compounds and their compounds can be Sulfonated. Carboxylic acid and alcohol can undergo ester reactions. Halocarbon, ester, glycan, disose, and protein can undergo a cleavage reaction under certain conditions. The reactions of alcohol, alcohol, and carbolic acid with active metals such as Na (also a substitution reaction) can be carried out. The reactions of alcohol and hydrogen Halide (HX) can be carried out. Carboxic acid or alcohol can undergo intermolecular dehydration reactions. An addition reaction is a reaction in which the saturated carbon atoms in an organic compound directly combine with other atoms or atomic groups to form a compound. In middle school chemistry, compounds with double bonds or triple bonds in their molecular structure could undergo addition reactions, such as alkene, diene, alkyne, and its homolog. Aldol, keton, and higher fatty acid, as well as their glycers and monosomes. Usually, the organic reagents involved in the addition reaction include small molecules such as H <2>, X <2>(X is Cl2, Br2, I), HX, H <2> O, and HCN (symmetrical or unsymmetrical reagents). However, it was important to note that the carbon-oxygen double bond in the ester group and the ester group could not undergo an addition reaction. In addition, except for carbon dioxide, which did not contain hydrogen, most organic substances could undergo an oxidoreduction reaction (because they could be burned). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
