Chemistry is really difficult in junior high school 5, chemistry in junior high school is really dif

Hello this classmate! I am a chemistry teacher and have been teaching chemistry for six years, and it is common for most students to have a situation like yours. In fact, it is not difficult to study hard, as a new subject, most students will have this situation with you.

Chemistry in the third year of junior high school is more literal, so it requires more knowledge points to memorize, which requires students to work chemistry. It is recommended to focus on textbooks first, then do some in-class exercises, read some tutorial books (after education reform, there are too few knowledge points in textbooks now), do more practice questions, and summarize and learn knowledge points through questions!

You can't panic at this time... The basic shape of the foundation has been finalized... What you have to do is to be able to take a point is a point ... CALM YOURSELF DOWN ... Let's look at it page by page... Maybe you'll get a few points you didn't even notice.

And according to my experience ... Read more books... It's better to see the book as a very yellow, very yellow kind... To learn to chew words, if you don't understand, ask the teacher... At this time, it is obviously impossible to dig deeper by yourself.

Work hard,,, mindset is the most important thing ... My junior... Brother is optimistic about you.,You can send a question to show that you still want to study.,So your hope is great.。。。 Calm down and study.

Chemistry is a subject that focuses on the basics, so I usually read more textbooks and do more exercises. Just remember more things that need to be remembered. Chemistry is not difficult. Diligence and practice!

Do simple questions first, and then do difficult problems, you won't just ask the teacher, anyway, there are easy to difficult, as long as you study little by little, you will definitely have a clue.

In fact, this part of the content is not difficult, and what you think is difficult should be that you have a good foundation in chemistry that you have learned before. It is not difficult to tackle the chemical formula and chemical equation first, and then look at the acid-base salt.

Take a look at the basic knowledge, the principle of the reaction, acid-base reaction is acid-base neutralization, and under normal circumstances, it is back to produce precipitation, salt, water, etc. Read more books. It's easy to figure out the principle.

To grasp the most basic, first understand the first 20 elements, and then understand the valence, the acid-base salt part to understand its main atomic clusters, and the fertilizer to know a little.

If you don't understand it, you will be scared first! I'll understand it later!

The chemical general formula of acid-base salts is mainly remembered, and the solubility table is also included.
