【中2理科c7】化学反応式を書いてみよう！化学式を使うよ！(言葉の区別ついてる？)

While there's a common suggestion to just write things down to memorize, the effectiveness of this approach depends on what you're studying. It's a good idea to write a lot of things like kanji and English vocabulary, because you'll remember them better if you "get used to seeing them while writing them down." Be careful not to overwork your hands. However, some chemical reaction equations are quite long, so memorizing long chemical reaction equations can be quite difficult. Instead, I think it's better to understand the state of a chemical reaction, the chemical formula of a substance, and how to match the numbers, and then create it on the spot. To avoid confusion like, "Huh? Do I write 2 here?", if you understand why you need to write 2, you'll be able to answer questions without relying on memorization. Learning how to write them will ultimately enable you to write chemical reaction equations for any chemical reaction. Memorizing everything is tough! I've summarized the content of this blog post.
