Does chemistry have to be studied well? Is chemistry easy to learn?

Not necessarily, but some of the common ones in daily life can be commonly used and should be known, and then your career orientation, if you develop into chemical engineering, medicine, etc., then chemistry is very important in your work. Overall, it doesn't hurt to learn a little better.

It is necessary to learn well, in order to increase knowledge and broaden horizons.

It's up to you, for example, a painter doesn't have a lot of effect, right, but what does it matter if you know a little more? It can save lives at critical moments.

Not necessarily, it depends on your interests, but also on where you work.

It is necessary that in the future, universities will pay a lot of attention to this subject.

There is no harm in learning well, and some of chemistry also includes life, which is good for you anyway.

Of course, that's how I came here, I just didn't learn chemistry well, and now I'm getting a score in the exam!

As far as the current test-oriented education is concerned, it is better to study as much as possible!

It depends on what you're going to do, and you have to do a good job in college chemistry.

If you want to study science, you must study well.

It's not necessarily, it depends on personal favorites.

Interest determines hobbies, hobbies determine whether you can learn well, and if you don't have that talent, it's useless to learn.

There is nothing bad for you to study well, and chemistry also includes life, which is good for you anyway.

You can simply understand some common sense chemistry knowledge. If it weren't for this kind of professional work, I don't think it would be much necessary.

It depends on whether you're interested or not, but it's not bad to learn well

It doesn't necessarily depend on what you do in the future.

Yes, otherwise you don't know some common sense.

At the very least, it will be useful and good for you.

What? Isn't it true that you don't have to learn every subject well? You can only give up unless you study liberal arts.

You are so powerful that you can ignore him.

To be honest, chemistry is difficult, especially in the college entrance examination in recent years, and chemistry has become more and more difficult, even surpassing physics as the most difficult subject.

First of all, the difficulty of chemistry is that it is varied, there are dozens of elements, and the problems that can be solved through different properties are endless.

Secondly, the difficulty of chemistry lies in the fact that it sets a lot of thresholds, which requires rigorous thinking and cannot guess the problem, and the reaction is likely to be very different if the conditions are different.

Finally, chemistry in recent years has been increasingly focused on the development of competencies that cannot be accomplished through hard work.

By learning chemistry by memorization, there is a dead end, but as long as you master the various properties, you will feel that chemistry is very fun and amazing, this can become that, that can change back again, the situation is alive, the nature is dead, and it is still easy to learn to use properties flexibly.

To give you an opinion, mathematics is to be learned anyway, if you feel that you are doing math problems, your thinking is very broad and sensitive, and you will not miss the definition of anything, for example, the definition domain of a function is basically not wrong, chemistry is too simple for you.

On the other hand, if you find it painful to solve the problem, then don't study chemistry, there is no need to gamble with your future.

I think it's easy to learn, mainly because I like it more. If you are interested, listen carefully in class and take good notes, solve problems in time, and then add some talent and lack to make up for with hard work, chemistry is not difficult.

It's really hard to say, everyone's own conditions are different, but there is one thing: as long as you want to learn chemistry well, you can definitely learn it well.

It depends on your interest, a thing, as long as you are willing to learn and work hard, there is nothing that you can't learn.

(1) There are indeed a lot to pay attention to, but first of all, you must relax, and don't be nervous.

1. When multiple-choice questions, it is best to finish them in 10-15 minutes to be fast and accurate.

2 Fill in the blanks must pay attention to details Equations and words must be written correctly There is a saying that details determine success or failure.

3 If you don't have an idea, write the equation first, and you will be given points for writing a few steps, but don't worry, because the general score will not be too high.

If you play well in the selection and fill in the blanks, the score will still be high.

2) The last sub-question of general chemistry.

is the solution calculation.

Most of them will have two solute volumes, and the total amount of the solution to be used - precipitate (gas) and so on.

So find a good solution solute so that it's fine.

You can do some of these kinds of questions, up to 5 questions, and you're good to go.

Hope it helps.

c) o(o..)My suggestion is not to talk about experience, it should be that I am about to pass the high school entrance examination, but I still want to talk to you about some of my own thoughts.

First of all, don't mess up, because chaos won't solve any problems, and impetuous emotions are not conducive to your thinking, so be sure to calm down.

There are a few little ways that I feel good. Now the teacher has homework that is almost all papers and memorization.

It's best to pinch the time to do the questions, so that you can improve your efficiency and not be very nervous during the high school entrance examination, prepare a small book, you can memorize homework, and some small knowledge points taught by the teacher in class, questions you don't understand very well (just write the number of homework) to save time and write some motivating words to read from time to time.

In short, you must memorize the knowledge, the foundation is very important, and the best use of the class time is not to discuss problems with other people, which will make you pick up sesame seeds and lose watermelon.

Time is precious now, so be more productive, such as getting everything ready at the end of the day, getting into the groove early, getting it sorted out quickly after school every day, and going home early (which will save a lot of time).

It is best to organize the key questions that the teacher talks about every day in a book from now on, and it is possible to sort out hundreds of questions in 14 days, of course, don't be greedy, but must be typical and important.

Communicate with teachers and make full use of teacher resources.

When I first learned chemistry, I had to memorize the valency of each element, and then I learned about the properties of a substance, especially the properties, chemical reactions, etc., I learned chemistry in high school, and I think it is not difficult, as long as you remember it carefully, the teacher will let you remember things.

Chemistry. Although I'm 1 in junior high school, I read a lot of books. Mainly memorize equations, which are similar to English. There is nothing difficult in the world. In fact, as long as you memorize it, it's not difficult. If you don't want to memorize. Just, listen well in class. Let's read more books.

Answer: 1. Understand the various reaction chemical reactions, including reduction reactions, oxidation reactions, chemical synthesis reactions, decomposition reactions, acid-base neutralization reactions, etc. In chemical reactions, we must firmly grasp the change of valency, and knowing this, I believe that it is not difficult to react. 2. Doing as much experimental practice as possible is the only criterion for testing the truth, so experiments also account for a considerable proportion.

You need to understand the use of some experimental equipment, such as: condenser tubes, test tubes, iron frames, alcohol, etc. In addition, when doing experiments, you must pay attention to your own safety.

3. Before class, the teacher will often talk about the difficult and easy to mix points, and before the teacher speaks, you must prepare for the preview. 4. Connect the knowledge points of life and learning, and connect them with actual life. For example, iron rusts because iron undergoes a slow oxidation reaction in the air.

Dear, the most important thing is to be interested in chemistry, the chemical reaction itself is a strange question What should I do if my child is in his first year of high school this year and is not solid in chemistry in junior high school?

In fact, chemistry is very interesting, they are all related, I am engaged in chemistry education, you can contact me.

To learn chemistry well, rote memorization is not advisable, the key is to master the method!

There is a lot to remember and a lot to calculate in chemistry. Junior high school chemistry is mainly qualitative, and there are many things that need to be memorized; In high school, chemistry is mainly quantitative, and there are many topics that need to be calculated. Therefore, in order to learn chemistry well, you must not only memorize a lot of content, but also master the method of calculation.

There's a good way to do it with chemistry rote. For example, use homophonic memory, mantra memory, etc. The teacher will also summarize a lot of mantras for the students, which is easy to remember.

For example, the elemental valency formula: "Monovalent potassium, sodium, hydrochloride, silver, divalent oxygen, calcium, barium, magnesium, zinc, aluminum, trisilicon, tetrasulfur, 246, 35 valence, nitrogen and phosphorus, iron, 23, carbon, 24, copper, mercury, 1, 22 valence." ”

High school chemistry has a lot of content and a lot of knowledge points. It is necessary to process and refine knowledge from time to time, and construct it according to its internal laws, so that knowledge that seems to be chaotic can be structured, organized, and systematized. In this way, the textbook can be changed from thick to thin, and the knowledge can be easily grasped and applied.

For example, compare similar knowledge and distinguish their similarities and differences; Summarize regular knowledge; Summarize the common knowledge and make it a knowledge block; Connect connected knowledge to make it a knowledge network.

In the study of chemistry, the purpose of digesting knowledge and improving ability should be achieved through regular practice. Exercises should be timely and appropriate, and fully use various forms such as written answers, oral answers, and experimental operations. It is necessary to repeatedly contact a variety of question types such as choice, fill in the blanks, inference, proof, identification, and calculation, so as to consolidate knowledge, train thinking, and cultivate ability.

It is necessary to give full play to the effectiveness of each question, touch on the analogy, and draw inferences from one example. Some problems can be solved more than one problem, which can open up the idea of solving the problem and improve flexibility; Some problems can be solved in one problem, highlighting the essence of the solution and deriving the law of the solution.

As for the experiment, first of all, the class should carefully observe the operation and experimental phenomena of each demonstration experiment made by the teacher. Secondly, we should pay attention to life and link theory with practice. The material world we live in is closely related to chemistry everywhere and at all times.

We need to learn to think analytically. It is necessary to be good at thinking from the individual to the general, from the phenomenon to the essence, from the special to the law, to grasp the essence behind each experimental phenomenon, and to understand the principle of each key step, so that we can draw inferences from one case and not be afraid of difficulties.

Don't memorize the new knowledge in isolation, but organically connect the old and new knowledge to remember. For example, when learning redox reactions, it is necessary to memorize them in connection with the knowledge of valency learned earlier, which not only consolidates the old knowledge, but also deepens the understanding of the new knowledge. The knowledge that must be memorized is very easy to remember if it can be condensed into a song recipe and catchy.

For example, the valency of the elements can be compiled: "monovalent potassium, sodium, hydrochloride, silver, divalent oxygen, calcium, barium, magnesium, zinc, aluminum, trisilicon, tetrasulfur, 246, 35 valence, nitrogen and phosphorus, iron, 23, carbon, 24, copper, mercury, 12 and 2 valent up. Another example is the key points of the experiment on the reduction of copper oxide by hydrogen can be compiled into:

Hydrogen is turned on first, then the lights are lit, and the heating is stopped and then the hydrogen is stopped.

Chemistry is a science subject, and if you want to learn chemistry well, you must first lay a good foundation. Chemistry is not a purely back-to-back subject, but there are some chemical equations that must be mastered. There are also some technical things, such as cross-trimming in redox.

There are also the three major conservation in salt hydrolysis and the various reactions of functional groups in organic chemistry, which need to be practiced continuously.

If you find it difficult to study chemistry, you can find a chemistry teacher and find some ways to do the problems. You must know how to ask for help and find a suitable method in doing the questions in order to effectively improve your chemistry scores.

There are many knowledge points in chemistry, so first of all, we must be familiar with the knowledge points, and secondly, we must conduct more hands-on experiments, observe more and think more to understand.
