Several basic laws of chemical reactions, the law of conservation of mass, the law of conservation of atoms, the law of conservation of energy, these three laws are all introduced in your textbooks, and I won't talk nonsense here. >>>More
Conservation of electric charge. Manganese changes from 7-valent to 2-valent, giving five electrons. The oxygen in hydrogen peroxide changes from negative 1 valence to 0 valence oxygen, losing two electrons. >>>More
I think it's better to read more books, books are the foundation, so that the chemical equations are not much use, and it is simple to understand and look at these equations after reading the books.

Hey, I don't even want to write about it, didn't you learn all this in the academy?
