The foodie in chemistry class
Thread Content
Is there any more food? In the chemistry class, the teacher explained the relationship between solvents and solutes: \"A certain solvent can only dissolve a certain amount of solute.\" For example, if you eat one bowl of rice and then another bowl, and you’re already full by the time you eat the third bowl, can you still eat any more? A student asked, “Are there any vegetables too?” In one test question, there are four substances: A, B, C, and D. A and B can be converted into each other; when B is heated, it turns into solid C. If B is left alone for a long time, it turns into D, which has the smell of rotten eggs. What are A, B, C, and D? A student replied: A is a chicken, B is an egg, C is a cooked egg, and D is a rotten egg.
Is a chemical reaction occurring between ABCD?
The answer is completely correct:lol:lol
;P:victory:
Gourmets are everywhere, lol
This can be considered a series of physicochemical and biological changes. . .

The ABCD items were used to ask colleagues; by analyzing them individually, it was determined that A and B are allotropes of sulfur, C represents sulfur in an oxidized state, and D is hydrogen sulfide, as inferred from its odor. . . People with science and engineering minds can’t think flexibly, haha~
