1. ### How do i get the answer? I can find the multiple choice answer but idk how they got it. Chemistry?

The atomic weight of chlorine is easily looked up: 35.453 amu Now, we can solve your problem: 35.453 = (34.9689) (x) + (36.9695) (1 - x) Solve the above for x to find the decimal abundance for Cl-35. Multiply that value by 100 to get the percentage. 1 - x will give you the...

7. ### Is it possible for a compound at a given set of ambient conditions to be thermodynamically stable but kinetically unstable?

If the compound is thermodynamically stable , it won't undergo a change, so no, this is not a possible situation. The converse (kinetically stable but thermodynamically unstable) is quite possible, though.

9. ### What exactly is energetic stability?

energy stability is like a trough in a rock where water accumulates and won't drop further unless pushed over the lip of the trough (the energy in this analogy is gravity).  The only question is how high up along the cliff is that trough? When an atom...
