Regarding the orientation of articles, I recommend one more category—comprehensive. Otherwise, if you call me Danmei + Lily + Romance, how can I choose? = =
By chance, the question came from a chemistry question I had done before.
Mg2C3 has the properties of carbide (such as CaC2: calcium carbide).
What is the chemical equation for the reaction between Mg2C3 and water?
The chemistry teacher said elegantly: "Isn't this question very simple? In this case, just exchange partners."
PS: The true meaning of exchanging dance partners is: Propylene, you still have the three keys~
So, small support, small attack, small T and small P, guess how to exchange... Full arrangement or combination?
