【中2理科c11】物質どうしの結びつく質量の割合。銅と酸素が４：１とかマグネシウムと酸素が３：２とか。（定比例の法則っていうらしい）

This time, I tried to test the tempo by asking myself, "How fast can I speed it up?" and it turned out to be incredibly difficult. I recommend pausing the video. Sorry. Trying to fit an experiment that normally takes about three hours into five minutes turned out to be incredibly difficult. It's called the "law of definite proportions," but I didn't mention it because that term wasn't in the textbook. There's a limit to how much matter can bind. Everything has a limit. Even copper and magnesium can't compete with oxygen's fierce attack, right? [Table of Contents] 00:00 Bonding with oxygen makes things heavier. 00:54 Check out the relationship between metals and the oxygen they bond to! 01:19 What mass of oxygen bonds with copper? 03:11 What mass of oxygen bonds with magnesium? 04:14 Summary. The bonding ratio is fixed and constant. Thanks for watching! See you next time!
