What are the jokes about classic organic chemistry?

In other words, once in class (probably introducing metals), she held a magnesium strip in one hand and an aluminum foil in the other, and said: "This is magnesium, this is aluminum, then together they are ——Magnesium aluminum.” (At the last two words, all the boys in the class shouted: Beauty!)

1. Calcium oxide and calcium hydroxide are the same. ——How shocking!

2. When several reactions are carried out at the same time, the first one to bear the brunt is acid-base neutralization.

——Typical misuse of idiom Ing?

3. When concentrated sulfuric acid splashes on the skin, what is the first reaction? ——Screaming of course!

——Drink advertising?

4. I was doing an experiment in the next class today and accidentally proved that human skin contains carbon.

(Referring to his finger being accidentally burned and turning black)

——A moment of silence for you?

5. Put zinc into the solution. This is called "rest assured"!

——So is putting zinc in a jar called "care"?

6. Does zinc replace iron or copper first? Doesn’t it pick out the soft ones first and bully them? ——Another shocking "chemistry saying"

7. Are there two kinds of solutes in the solution? Are they two kinds?

——Please, don’t speak so funny even if your English is not good!
