Hello everyone, I had my final exam yesterday, in which we had to identify a mixed salt using the separation process and find the ions it contained. My salt was light pink, fine/powdery. Likewise, in the (NH4)2S group, I got a light, orange/pastel-colored precipitate. So everything pointed to manganese. When I then poured the filtrate…
Hello Community, I'm in 9th grade, and our school is offering a dance class with the class—voluntary. I'm considering taking it, as it's definitely a great opportunity. How should I prepare for this if necessary? What should I wear? (suit or casual clothes) Should I arrange to go there with someone? (since it's probably a…

An enzyme is a catalyst. And a catalyst only reduces the activation energy, but does not change the reaction itself.
You see here:
The activation energy of X-> Y is the height of the “buckle” of X. :e energy that becomes free is delta H and that does not change when the activation energy is changed.
thought experiment:
Imagine you’re packing the whole experiment in a big bag, where nix gets out but also nix gets in and no heat or other energy (light or radiation) passes through.
Thus, before and after the reaction, the same amount of matter must be in it (quantum physics and E=mc2 leave out as in this thought experiment) and before all the same amount of energy must be there. The energy can be heat, light, radiation, pressure or chemically bound energy.
So we have to
Sum of the energies of the reagents before = sum of the energies of the reagents afterwards
Enzymes do not change through the reaction. There are catalysts
Thus,
sum of the energy of the enzyme before = sum of the energy of the enzyme afterwards
If you now serve reagents to pack the enzyme and write the previously-after equation again, you realize quite quickly that because the energies that the enzyme brings nix change the energies of the reagents before and after each have to be the same no matter whether the enzyme was present or not.
