Sophomore chemistry enters the field of organic, but the real difficulty is related to inorganic, if you learn inorganic well, it is not difficult at all. Otherwise, if you don't get it right, you will feel dazzled.
In fact, chemistry only grasps the essence of reactions, and even chemical reaction equations do not need to be memorized, and only the properties of a few substances need to be memorized.
However, if you don't understand the essence of chemistry, studying chemistry will become a liberal arts such as politics and history.
If you decide to choose chemistry, it is recommended to learn about the properties of the SPD f orbital, which encompasses almost all the knowledge of high school chemistry. And the periodic table of chemical elements is naturally memorized.
-
The nature of the SPD F track is the category of the university, so you don't need to memorize it, but if you are interested, you can learn about it.
Notation Chemistry Learning is! The process of memorizing + writing questions + asking questions. No, just ask! Even if you are not good at math, you can learn it well! Less logical and analytical than physics requires! So it's easier to learn!
-
OK. Much better than physics.
-
High school chemistry is the most important textbook to familiarize yourself with, read it as many times as you can, and I think it's just like English, and you can read a lot of things, as long as you remember the periodic table.
-
High school chemistry is to memorize, and geography is about the same, and there are so many old questions, or not as good as geography, I don't know how you are at math.

Summary. Pro-<>
As long as you memorize the equations and solve the calculation problems, the chemistry score will naturally improve. But this is only part of the story, and there is also the experimental part that needs to be worked on. Some equations need to be memorized directly, while others can be leveled by themselves, although it may be a waste of time.
If you want to learn chemistry well, it is not enough to memorize it, you also need to do a lot of exercises to train, practice makes perfect.
Is chemistry hard to learn in the second year of high school.
My <> will be happy to answer for you, it will be more difficult to promote Bulu chemistry to the second year of high school than the first year of high school. Chemistry in the second year of high school has high requirements for the basic knowledge of the first year of high school. If the foundation of the first year of high school is not good, it is particularly difficult, and sometimes a failure inference problem or calculation problem is enough for you to calculate for half a day. <>

To put it simply, there are two key points in learning chemistry:
1. Construct an independent knowledge framework, i.e., trunk and branches.
2. Chemical language: Chemistry is a natural discipline, including the classification of substances, along with the gradual deepening of the concept, the chemical language should also be gradually deepened, such as the most basic chemical equations, from redox to periodic law.

My chemistry was suddenly enlightened after a week of frenzied work on questions in the second semester of my third year of high school, and my score suddenly went from a score of more than 95 points to a score of more than 95, and I never came down again. I always tell my child about it, and he always scoffs at me when he knows what I'm saying is true, and I can't do anything about it. I was a high school student more than 20 years ago, won a national physics competition, and now I am engaged in chemistry research.
A few days ago, I saw high school chemistry exercises, especially the organic chemistry part, my estimation is: even the front-line teachers in high school may not understand the mystery of the four major spectra, especially the mass spectrum and nuclear magnetic spectrum, because this is indeed the synthetic judgment center of organic chemistry, I went to study abroad, and I only thoroughly understood it after reading the spectrum every day, and now there are special readers in the world who judge the molecular structure through the spectrum, and the ** of each spectrum reads is: 2-5 US dollars.
Is it difficult for today's middle school students and teachers to have million-dollar MRI machines as teaching aids? I really don't understand why it's so hard to learn high school chemistry? Science is quite interesting, but I really don't want you to listen to other people's blind summing up experience, but you still have to listen to your own inner voice!
Got it? Think for yourself, there will be many problems in the future, all of them are very important!

Chemistry is a liberal arts subject in science, which is to rely on the back, followed by understanding, and the basis of memorization is to devote yourself to class and carefully understand what the teacher said. Chemistry is not like mathematics, only the brain is good, you must memorize more!
Chemistry is a fascinating subject. However, due to the characteristics of high school chemistry as "complicated, difficult, and chaotic", many students find it difficult to learn high school chemistry. So how can you learn chemistry in high school? >>>More
I'm thinking about Eun, in fact, organic is the simplest, you look at the problem specifically, in fact, it is enough to memorize the reaction of each group. >>>More
The charge is evenly distributed on the outer surface, and the electric field in the cavity is 0, which can be distributed in any case if it is not a conductor. >>>More
Under normal circumstances, this situation is not feasible, not that you cannot transfer your student status, but you are not allowed to re-enter the second year of high school. Unless there is one case, that is, you have taken a leave of absence due to illness and have not completed most of the courses in this section, so you can only choose to repeat it. There are no physical reasons, but it is a little difficult to simply choose to transfer schools and re-study for another year. >>>More
Absolutely! I believe that through your continuous efforts, your math score will definitely improve greatly in the final exam! The following New Oriental ** provides a learning method for the final review of high school mathematics to help you! >>>More
