A good way to review chemistry in high school and a good song in English

Let's talk about my experience, and to summarize the high school chemistry framework, there are three points: one is the theory of chemistry, and the other is the combination of elements.

The third thing is organic.

Let's start with the theory of chemistry, the three major theories, the theory of the structure of matter, the theory of electrolytes, and the equilibrium.

There are more things that need to be understood, so it is important to do the questions appropriately and strengthen the understanding of the concept Some are small.

Memorization is useful.

Elemental compounds, which are the foundation of high school chemistry, run through the entire body of knowledge, so it's important to grasp it very well.

Okay, good, good, good, look at how good I use, you should know how important it is, I say that.

It's because I just got my chemistry up by myself.

The secret is to take all the chemical equations that you learned in high school and write them in the order of the main family, so that you can take them.

We all remember and have a holistic grasp of chemistry.

And then you can classify all the important substances that come up, for example, liquefiable substances, and you immediately think of NH3, SO2, N2

And that's it, when doing the inorganic inference problem, you can immediately think of the substance based on the description of the properties on the question, and it won't.

Waste of time and lab problems will also use this property to design or solve.

And finally, let's talk about organic, and some people say it's difficult, because they haven't learned it, and organic is probably the most regular in chemistry.

As long as you grasp the rules, it is easy to be organic, and it is important to be very familiar with it and not to mix it up.

The equations are organized according to their reflection conditions, for example, when you see concentrated sulfuric acid, you think of hydrolysis to ethylene.

To make nitrobenzene and so on, but also to classify them according to the substance, that is, for example, aldehydes, aldehydes, to make their chemical reverse.

All types should come to mind.

Almost, to be honest, I just summed up all the chemical equations at once.

Gradually improve up to 108 out of 100 points, basically 100 points, this chemistry is still my weakness, so do it, kid.

And if you're a freshman (I just finished the college entrance exam), don't worry, it's for all subjects, you're good to go.

Learn no matter what else do you know about epiphany The third year of high school is a stage of epiphany, and a lot of you are not very good at it.

Come and you'll suddenly realize that this is a qualitative change that you have accumulated.

Hehe, finally, I wish you a happy high school and success in the college entrance examination!

If you want to say the English song Avril Lavigne Eh Lincoln Park song I think it's so good faint in the end la.

Heh.

To learn chemistry well, you need to take more notes, record the key points of the teacher's lectures, and read them often, I have a chemistry notebook, remember everything, good topics, equations, pay attention, I don't even need to turn the book.

Good English song: forever young tell me why

There is no good way to do interest in the most important place. When I was in high school, I was very fond of chemistry, and I read it with interest and I could remember it once I read it. As long as you read the book carefully and carefully, don't care what the teacher said or not, and then do a few sets of test papers to monitor, there is no problem at all.

It took me a month to read 3 books on high school chemistry in my first year of high school, and after I finished understanding it, I flipped through it every time I went to the toilet, and most of the subsequent exams were close to full scores. Chemistry and biology are very suitable subjects for a one-time breakthrough in concentrated time, because there is no anti-lock calculation, so, go for it!!

Take me to your heart is also the English version of kiss goodbye, the melody is good and you can keep up,

pretty boy.The melody is good, and Adele's Rolling in the Deep, and The Show, are all good.
