Is chemistry difficult? How hard is chemistry exactly

Chemistry is half a liberal arts, and many of them have to be memorized, and if you don't remember well, it's very rare, and you have to memorize them by rote. But if you can memorize everything you should memorize, there will be no big problem if you understand what the teacher is saying.

Personally, I don't think it's difficult. And I think chemistry should not be a lame subject, it is very flexible, very detailed, it takes a little time to summarize, it is only necessary to listen carefully in class, with this, in order to have the guarantee of good grades, follow the teacher's rhythm, on time, complete the homework seriously, your chemistry will not be bad.

Chemistry is not difficult, chemistry describes the nature, use, preparation method, constituent composition, manufacturing method and other contents of a certain substance. As long as you observe carefully, think carefully, and be good at memorizing, you must be interested in chemistry.

Whether it is difficult or not can only represent personal opinions, and it is not difficult to learn well, but it seems difficult to learn badly. As long as you study hard and study hard, it is not difficult, and interest is also very important, and if you are interested, you can consciously learn, so you must cultivate your interests and hobbies.

The ancients said, "Is it difficult to do things in the world?" If you do it, it will be easy for those who are difficult; If you don't, it's easy and it's hard", my chemistry is actually not difficult at all, he is much easier to learn than physics.

It's not difficult, as long as you learn by heart, everything is very simple.

The key is to practice more and master the basic techniques in practice.

The main difficulty of chemistry is that the knowledge system is much more fragile than physics.

Let me give you an example, the law of physical buoyancy.

Let's talk about it. [You know: The buoyancy of an object in a liquid is equal to the gravitational force that displaces the volume of liquid. This experiment was done in the first physics class

Chemistry hypothesizes that this law of buoyancy is also being studied, but what happens to it? --

First, we found that macroscopic wood floats on water, and we concluded: the law of object floating: objects can float on the surface of water.

But we soon found out that there was something wrong with this law, the iron was thrown in and sank, and we came to the conclusion: the law of floating wooden objects: wood can float on the surface of water. Block of iron.

No. But then we discovered that plastic can float too, so we started to define the law of wood-like objects: wood-like objects can float on the water, but iron-like substances cannot.

But then we found that if we changed the shape of the iron block and made it into a large iron ball, or a boat, it could float, so we got a new law: iron-like substances can float on the surface of the water under certain conditions.

So what is wood-like and what is iron-like? Then we threw all kinds of things into the water to test it, and we accidentally found that the salt and the like were thrown in and he was gone, so we made another salt-like substance.

After tossing and turning for a long time, we still haven't found out what the real law of floating is.

The difficulty of chemistry, in my opinion, is the study of material change, and the knowledge points are too scattered, so that in the popular science stage (before high school), there are too many things to memorize, and at the same time, it is too trivial, so that I can understand it in class, but I don't know anything after class. This is very different from physics.

At the undergraduate level, chemistry or related majors begin to combine physics and mathematics to build bridges for the knowledge system, and this stage is extremely long (almost 2 semesters). Take climbing a mountain as an example, that is, in order to see the scenery, most of the time is spent on the road, and it is extremely hard in the middle.

Those who really saw the scenery and came into contact with the beauty of chemistry finally didn't feel that it was difficult for him, after all, he was only the last few people.

The overall accuracy of chemistry is in a higher position among the six elective subjects, basically second only to the theory of physics, but the specific difficulty also depends on the student's learning ability and his own way of thinking.

The most efficient ways to learn high school chemistry are as follows:

1. Preview before the basic poor class.

We all know the truth that the stupid bird flies first, due to our poor foundation, our learning must be ahead of others, it is recommended that students with poor foundation must preview before class, so that the old knowledge related to it can be reviewed. If you don't understand, you can mark out the key points of the class to listen, so that you can listen to the class with questions, because you have already studied by yourself, it is easier to keep up with the teacher's progress when listening to the class, and there will be no loss of confidence and reluctance to listen to the phenomenon that you don't understand.

2. Memorize the periodic table.

The most important thing in learning this subject is to remember the periodic table, which is equivalent to a map of geographical summaries, which accounts for a considerable amount of weight, as long as you learn the memorization formula of the periodic table, then the improvement of chemistry scores is very fast. Therefore, that is to say, the key to a good science is to memorize the periodic table, if students want to improve their grades quickly, then they must first memorize the periodic table, which is a prerequisite.

3. Have a plan to review knowledge.

High school students should wait until their knowledge is relatively complete before reviewing, focusing on what they don't know, not memorizing all the knowledge, but to grasp the essence of the problem of missing knowledge points in each paragraph, but don't forget to consolidate the knowledge they already know, and at the same time you can use the three-time review method to improve your learning efficiency. <>

It's not difficult to drop the chemistry junior high school course, and you will be able to listen carefully to the class, hehe, it's really simple.

As long as you memorize the equations, you can learn chemistry well.

The content of junior high school chemistry is simple and easy to understand, but some topics are still relatively difficult, so you must be proficient in the knowledge in the textbook and supplement the practice after class, you can still learn very well!

Whether it's difficult or not depends on yourself, if you take class and listen to the class well, it will definitely not be difficult, of course, if you don't listen to the class, it will definitely be difficult.

This is a kind of self-confidence problem, many times it is the psychological suggestion chemistry that I give myself is particularly difficult, so it is difficult to learn, and other subjects have the self-confidence to learn well, so it is easier to learn.

Me too. I really feel that those precipitations, except for miscellaneous concepts, the teacher can't remember them at all, and he can't start when he sees the topic. I don't know what to memorize when I go home, because I suddenly feel a lot of what I said in class, and I don't even feel confused because I can't remember it at all!

The stage test is 59 points, which is very uncomfortable. I really can't understand the words of my classmates, and it is difficult to explain the reaction of chemistry, why it is exothermic and endothermic, how to remove impurities, and how to see coexistence. Obviously, I listened to the notes in chemistry class, but when I looked at it again, I had no concept at all.

Chemistry is to listen carefully in class, and the most important thing is to memorize the concepts and understand, remember to understand. When you understand it, you can kill the questions in seconds. The science and science school bully floated by.

Chemistry has too much to remember. Remember that the teacher's knowledge of chemistry is always better than yours, so don't let go of any words related to chemistry that the teacher said. Chemistry is a relatively simple subject in science.

Chemistry is a liberal arts major.

I also find it very difficult, especially where ions coexist, and I have no idea which ions can react to form gas precipitates and water.

Chemistry in junior high school is indeed not difficult, don't be resistant, calm down and study hard.

RT self-taught high school chemistry, compared to physics and mathematics, etc., how do I feel that physics and mathematics are very simple, there is a very rigorous logical deduction, can explain the reasons from the most essential, even if the formula is forgotten, it can be smoothly launched, do a question, this type of question will be done in the future, and I can understand what this question tests you.

Even if you know which elements react with and what the products are, you never explain how these equations come about, why the matter reacts like this, why it is combined like this, and I feel that there is a feeling of a blind man touching an elephant, not starting from the essence of the microscopic change angle, the most profound feeling is that the memory ability is greater than the deduction, the ability to think.

Chemistry can be said to be the simplest in mathematics, physics and chemistry, don't use too much mathematical knowledge, just know the basic addition, subtraction, multiplication, division and equations. I'm not very good at math, but I can still participate in the national chemistry competition.

Chemistry is mainly divided into: inorganic chemistry and organic chemistry. In junior high school, he only studied inorganic chemistry, and in the second year of high school, he began to study organic chemistry. The exam is mainly inorganic chemistry.

For inorganic chemistry, the most important thing to learn it well is to master the chemical properties of atoms, molecules, and ion clusters. Because all the chemical reactions are formed between them. When you go to high school, you only need to memorize dozens of them, and they can be categorized among themselves.

Other questions such as what substance, what color, what phenomenon the reaction has, etc., just memorize it according to your understanding.

As for organic chemistry, the main thing is to have an understanding of the back, remember what chemical bonds, hydroxyl groups, carboxyl groups and other properties of 10 or so seed groups, organic matter is the reaction between these groups, and of course there are conditions for this reaction. Mainly under different reaction conditions, different substances will be generated, and temperature changes can produce different reactions. The most troublesome thing I had when I studied organic chemistry was memorizing reaction conditions.

Mastering these, learning chemistry is a breeze, and no matter how diligent you are, it is common to get a perfect score in the exam.

It's not hard to be interested. In fact, we are inseparable from chemistry everywhere, but we don't realize it, for example, our home kitchen: the decoration materials used in the kitchen are manufactured by the principle of chemical reaction, all kinds of electrical appliances are the chemistry of smelting metals, and all kinds of condiments are chemical products of chemical plants, in short, don't be confused by the word chemistry, chemical knowledge exists in every part of our living environment, as long as you have an interest, learning chemistry is a matter of course, I wish you progress in learning.

Chemistry is not difficult, but the knowledge points are relatively trivial! There is a lot of knowledge that needs to be memorized, but this kind of memory is to be memorized on the basis of one's own understanding, which is different from rote memorization. Chemical equations and chemical element symbols are the language of chemistry, and chemical element symbols make up chemical formulas, which are the most basic and equivalent to our square words.

Chemical equations are the key to solving calculation problems and need to be mastered! For some conventional experiments, it is necessary to be proficient, the knowledge points of the chemical experiment test are relatively trivial, and the general examination is a series of questions such as the air tightness and rationality of the experimental device, whether there will be danger, how to make it more reasonable, etc., which are very small and very important! Chemistry calculation problems are still relatively rare, and they are relatively simple!

You'll understand this when you learn it!
