Is chemistry difficult in junior high school, and is chemistry difficult to learn in junior high sch

Chemistry and physics in junior high school are very simple, you have to listen carefully to the lectures, take notes, as long as you are interested, and you are very easy to learn.

And there are going to be some interesting little experiments that are interesting.

As long as you find a way, chemistry is actually not difficult, it is very easy. Good luck with your learning and progress.

It's not hard. At least I'm almost a perfect score.

It's not difficult, take the class seriously, and write the homework yourself. Also pay attention to the inductive solution method!

Chemistry is actually a liberal arts subject in science, there are many Chinese and Western subjects that need to be memorized, but there will be certain calculations, and many knowledge points need to be summarized, especially those of acid and alkali! So as long as you study hard, it's no problem!

Just read more books and take more notes.

It is not difficult, at this time, chemistry is still biased towards liberal arts points, and the periodic table of elements to memorize, and the reaction equation is the foundation, of course, understanding is also important.

It's not difficult The key is to see more, think more, think more, and think more.

It's not difficult, just memorize what the teacher said in class, and of course, science students still need to do more exercises.

As long as you memorize chemical formulas, it is not difficult, and of course you have to listen to the lectures well, I think it is not as difficult as physics and mathematics.

It's not difficult to learn, the key is yourself.

God helps those who help themselves. Let's study hard, especially the "Acid and Base Salt" under the nine. (People's Education Edition).

At first, it will be difficult to accept because it is relatively unfamiliar, but slowly it will be. But you still have to listen to the lectures and do more exercises, and chemistry in the third year of junior high school is very simple. Chemistry in high school is more troublesome.

Chemistry in junior high school is not difficult to learn. For students in many areas, the first time chemistry in school is in the third year of junior high school, and the chemistry at this time is some relatively basic and introductory things.

Chemistry and Physics are two courses of similar difficulty in junior high school as a whole, and both have corresponding learning methods. When learning chemistry, you can learn chemistry better by memorizing various chemical formulas, chemical reaction equations, etc.

The embryonic period of chemistry

From ancient times to 1500 B.C., human beings learned to make pottery from clay in a blazing fire, to burn metal from ore, to make wine from grain, and to dye silk and linen and other fabrics.

In ancient times, primitive humans discovered and used fire in the struggle against various disasters in the natural world for their survival. Primitive human beings began to use fire from the time of barbarism to civilization, and at the same time, they also began to use chemical methods to understand and transform natural substances. Combustion is a chemical phenomenon.

The discovery and use of fire improved the conditions for human existence and made the human race smart and powerful. ）
