Reasons why chemistry is hard to learn in high school:
Because the scope of high school chemistry investigation is relatively wide, involving organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry and other aspects, many of which are abstract and esoteric, and require a lot of memory and practice to understand and master.
At the same time, chemical experiments are also a very important part, but in the process of experiments, it is necessary to have a high degree of safety awareness and rigorous attitude, and have a certain understanding and mastery of experimental equipment, chemicals, chemical reactions, etc., so students need to invest more energy and time.
Extended Content: How to Learn High School Chemistry Well:
1.Build a strong foundation: High school chemistry needs to build on the foundation of middle school chemistry, so students need to review their secondary school chemistry knowledge and ensure that they grasp the foundational concepts.
2.Frequent problem-solving: In high school chemistry teaching, theory and practice are combined, and students need to do a lot of exercises to consolidate knowledge points and master problem-solving skills. Exercises can be practiced through workbooks, notes, teaching aids, etc.
3.Combination of theory and practical and anticipation: High school chemistry should not only learn theoretical knowledge, but also conduct experimental operations, experience the process of chemical reactions, think about experimental results, and deepen the understanding of chemical knowledge.
4.Focus on thinking training: High school chemistry is not pure rote memorization, but also needs to improve students' thinking skills. Through the practice of chemical thinking problems, innovative thinking, etc., students' thinking ability can be trained and expanded.
6.Interactive communication: Learning chemistry requires not only listening to lectures or self-study, but also communicating and interacting with classmates and teachers. Through class discussions, group discussions, experimental operations, etc., students' interest and effectiveness in learning can be improved.

High school chemistry is comparatively more difficult than junior high school chemistry, mainly because of the following aspects:
1.Strong abstraction. Some concepts and theories in high school chemistry are relatively abstract, which requires students to have strong logical thinking ability and abstract thinking ability.
2.The foundation of mathematics is highly demanding. High school chemistry involves some mathematical content, such as concentration calculation, acid-base reaction calculation, etc., which requires students to have a good mathematical foundation.
3.There are many knowledge points. There are many knowledge points of high school chemistry, and there are interconnections and connections between each knowledge point, which requires students to carry out comprehensive and in-depth learning.
4.The experiment is demanding. The requirements of high school chemistry experiments are more rigorous and detailed, which requires students to have higher experimental skills and safety awareness.
Therefore, the difficulty of high-purity chemistry is indeed relatively large, which requires more effort and time from students, and at the same time, teachers need to provide more detailed and systematic guidance to help students better master chemical knowledge and skills.
High school chemistry is a more important subject, and the following are several aspects of high school chemistry learning:
1.Develop the basics. The subject of high school chemistry is based on the knowledge of junior high school chemistry, so you need to first lay a solid foundation in junior high school chemistry, and gradually consolidate and expand the basic knowledge of high school chemistry.
2.Familiarize yourself with the key and difficult points. High school chemistry is relatively abstract, and special attention needs to be paid to key and difficult points, such as chemical reactions, chemical equilibrium, acid-base reactions, chemical bonds, etc., which are important knowledge points in high school chemistry and need to be studied and mastered in depth.
3.Learn chemistry experiments. Chemistry experiments are an indispensable part of high school chemistry learning, which requires students to master experimental skills and safety knowledge, and learning chemistry experiments can help students better understand the principles and concepts of chemistry.
4.Do your practice. Chemistry is a subject that requires practice and reflection on the part of the student. If you have enough theoretical knowledge, but without practice, you can't really master chemistry.
5.Interact with the teacher. Teachers are experts in chemistry and can provide guidance and assistance to students. Students need to make good use of the teacher's resources, communicate and interact with the teacher, and solve their own problems in a timely manner.
In short, high school chemistry learning requires a lot of effort and time, requires students to master scientific learning methods, and also needs the support and guidance of parents and teachers.

The difficulty of high school chemistry can be related to the following factors:
There are more abstract concepts: Compared with junior high school, high school chemistry pays more attention to the learning of theoretical knowledge and abstract concepts. For example, high school chemistry requires students to grasp concepts such as relative molecular mass and chemical bonds, and this kind of conceptual learning requires students to induct, generalize, and reason, which is relatively difficult.
Large amount of mathematical knowledge: Some content in high school chemistry is closely related to mathematics, such as the molar mass of a substance, stoichiometry, etc. Understanding these concepts requires a certain amount of basic knowledge of mathematics, but these mathematical knowledge is often a weak or weak link in students' habits.
High requirements for experimental ability: Chemistry is an experimental science, and the requirements for experimental ability in high school chemistry are relatively high. For students, mastering chemistry laboratory skills is a process of practice and exercise, and the lack of experimental practice for a long time will affect the understanding and application of chemistry knowledge.
The knowledge system is more systematic: Compared with junior high school chemistry, high school chemistry has richer theoretical knowledge, more complete system, and more practical application value. For students, high school chemistry needs to master more and more extensive knowledge content, and the requirements for students' memory ability and thinking ability are higher, which is also one of the reasons why high school chemistry is difficult.
The test evaluation is more comprehensive: the format of the high school chemistry test is not only a test of conceptual knowledge, but also includes different styles of question types such as analytical questions, calculation questions, and experimental design questions, which require students to master a variety of different solutions and skills. In addition, the chemistry test also has great requirements for language expression and reasoning ability, which is one of the reasons for the increased difficulty of high school chemistry.
In short, the difficulty of high school chemistry is mainly related to the learning of abstract concepts, the basic needs of mathematics, the experimental ability, the systematization of the knowledge system and the comprehensiveness of the examination evaluation. In the learning process, students need to summarize and summarize knowledge attentively, focus on understanding and summarizing the high school chemistry knowledge system, learn more about the combination of experimental practice and theory, master problem-solving skills, and improve the performance of chemistry through comprehension exercises.

High school chemistry may seem difficult in the eyes of some students, which may be due to several reasons:
1.More abstract concepts and principles: Compared with junior high school chemistry, senior high school chemistry introduces more abstract concepts and principles, such as atomic structure, molecular structure, chemical bonds, chemical equilibrium, etc. This requires students to have strong abstract thinking skills and comprehension.
2.Extensive knowledge: High school chemistry covers a large number of knowledge points, such as periodic law, redox reactions, acid-base balance, organic chemistry, etc. This requires students to grasp a large amount of information and concepts in a short period of time, which can lead to high learning pressure.
3.Experimental operation and experimental design: High school chemistry also includes certain experimental operation and experimental ear car design. These experiments usually require students to have strong observational, hands-on, and analytical skills.
4.Balance between comprehension and memory: High school chemistry requires students to strike a balance between understanding and memorizing lead. While comprehension is the key to learning, memorizing some basic concepts and formulas is also necessary for solving problems and exams.
5.Test-taking pressure: Students in high school face greater pressure on exams, such as the college entrance examination. This can make students more susceptible to anxiety and stress, which can affect their learning outcomes.
To overcome the difficulties of high school chemistry, the following strategies are recommended:
1.Make a proper study plan: Allocate your time wisely to ensure that you memorize and practice concepts based on your understanding.
2.Timely review: Regularly review the knowledge points you have learned, consolidate your memory, and ensure that you understand it thoroughly.
3.Ask for help: Don't be afraid to ask your teachers, classmates, or parents for help when you get stuck. They may be able to provide valuable advice and support.
4.Practice and application: Apply what you have learned to real-world situations and deepen your understanding by doing problems, participating in experiments, and participating in course activities.
5.Maintain a positive mindset: Believe in your ability to overcome difficulties and maintain a confident and optimistic mindset.
By adopting these strategies, students can gradually overcome the challenges of high school chemistry and improve their learning.

If you feel that chemistry is difficult to learn in the middle and middle school differential cluster sections, if it is not uninteresting, then the main reason is one, too unsystematic.
I often complain about the content of the current high school chemistry syllabus, focusing on almost any knowledge point, but this kind of comprehensiveness also leads to a weak system, and there is no theory to speak of.
But in fact, chemistry has principles, and the main line is the periodic law of elements, with the help of which most of the knowledge points of high school chemistry can be leveled.
The key is the question of how to learn. If you just follow the little things in the textbook and memorize them by rote, you will feel that the periodic law is nothing, not only is it very fragmented in nature, but there are also many special cases.
I'd recommend reading a little more essential. The periodic law of elements is a law that has been summarized by the efforts of several generations of chemists, and it is also one of the precursor sciences of quantum mechanics, and if there are not so many facts observed, quantum mechanics will not be so accurate in describing atoms. If you are interested in chemistry, or more broadly, and are interested in science and nature, then you will definitely not suffer a loss by taking a look at the mechanics of the Suiqing Youzi.
By learning the four quantum numbers, i.e., the principal quantum number, the angular quantum number, the magnetic quantum number, and the spin quantum number, and understanding the decisiveness of each quantum number on the chemical properties, some so-called special cases can be easily solved.
