In fact, there are not many equations for carbon group elements in high school. Suggestion: Compulsory one in the first year of high school.

I'm a chemistry teacher in my first year of high school, so what's the use of giving you all the ion equations? The key to science is to understand, just take a good look at the steps of writing the ion equation in the book and digest it. Just pay attention to what should be dismantled and what can't be dismantled, and the ion equation is not too difficult to learn.
All the substances, smells, and what you say are hard to find! I used to know that there was a **, but it may not have been recently! But there's a QQ group that you can add to it, and people here can talk about chemistry problems, and you can ask people in the group about the problems you have, and of course I can too! >>>More
