Question: 204
2. Which of the following substances has the atom with the greatest oxidation state?
- A. absorbed, internal energy decreases, and entropy decreases.
- B. released, internal energy increases, and entropy decreases.
- C. released, internal energy decreases, and entropy decreases.
- D. released, internal energy decreases, and entropy increases.
Correct Answer: C
Explanation:
C As a substance undergoes deposition, it becomes a much more ordered substance, decreasing entropy (eliminate choice D). In addition, heat will be released (eliminate choice A) because the potential energy of the substance decreases (eliminate choice B).
