Answer:

Hg∧2+ has a negative standard entropy because the ions are highly solvated in aqueous phase; smaller the ionic size, the more highly it is surrounded by solvated ions. Therefore it will be in highly ordered state hence the entropy decreases.

Hg2 ^2+ has a positive standard entropy because the ionic size of Hg^2+ is smaller than Hg2 ^2+, so therefore the Hg^2+ is highly solvated and that means that it is in highly ordered state. Hg2 ^2+ is not highly solvated so it will have a positive entropy

Explanation:

The values of standard entropy of aqueous ions has a negative standard entropy because the ions are highly solvated in aqueous phase; smaller the ionic size, the more highly it is surrounded by solvated ions. Therefore it will be in highly ordered state hence the entropy decreases.

What is the chemical symbol for element 2

Margarita [4]

Looking at the elements from period three, you can identify element 2 based on element 3. It shows that element 3 is Magnesium. The ionization energy increases as it goes from left to right.

Since Element 2 has a lower ionization, just think of an atom that is to the left of Magnesium because it has a lower ionization energy. The only atom to the left of Magnesium is Sodium. So element 2 is Na, or Sodium.
