Why does Hg2+ have a negative standard entropy

Chemistry
1 answer:
lidiya [134]3 years ago
4 0

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.

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

Stock nomenclature nh4no3
dedylja [7]

Answer: Stock nomenclature of NH_4NO_3 is ammonium(I) nitrate

Explanation:

Stock nomenclature is used for chemical nomenclature where the oxidation states of some or all of the elements in a compound are indicated  by Roman numerals in parentheses.

For example:

FeCl_2 which has iron in oxidation state of +2 has stock nomenclature of iron(II) chloride.

FeCl_3 which has iron in oxidation state of +3 has stock nomenclature of iron(III) chloride.

Thus the stock nomenclature of NH_4NO_3 is ammonium(I) nitrate as ammonium has oxidation state of +1.

How would a solute affect the boiling point of water?
Alex787 [66]
The answer is C. The water will boil at a higher temperature. This is because the solute is an impurity that raises the boiling point and lowers the melting point of water.

How many grams of naoh do you need to make 1 liter of a 10% sodium hydroxide solution?
frez [133]

Mass % of NaOH solution = 10 % (m/v)

Mass of NaOH required to prepare 1 L solution:

1 L solution * \frac{1000 mL}{1L} *\frac{10 g NaOH}{100 mL solution}

= 100 g NaOH

How many copper atoms are in a 70g copper
Artemon [7]

Answer:

x = 6.634\times 10^{23}\,atoms

Explanation:

The quantity of atoms within the mass of copper is determined by multiplying the quantity of moles by the Avogadro's Number:

x = \left(\frac{70\,g}{63.546\,\frac{g}{mol}} \right)\cdot \left(6.022\times 10^{23}\,\frac{atoms}{mol} \right)

x = 6.634\times 10^{23}\,atoms
