Answer:
ΔG° = -533.64 kJ
Explanation:
Let's consider the following reaction.
Hg₂Cl₂(s) ⇄ Hg₂²⁺(aq) + 2 Cl⁻(aq)
The standard Gibbs free energy (ΔG°) can be calculated using the following expression:
ΔG° = ∑np × ΔG°f(products) - ∑nr × ΔG°f(reactants)
where,
ni are the moles of reactants and products
ΔG°f(i) are the standard Gibbs free energies of formation of reactants and products
ΔG° = 1 mol × ΔG°f(Hg₂²⁺) + 2 mol × ΔG°f(Cl⁻) - 1 mol × ΔG°f(Hg₂Cl₂)
ΔG° = 1 mol × 148.85 kJ/mol + 2 mol × (-182.43 kJ/mol) - 1 mol × (-317.63 kJ/mol)
ΔG° = -533.64 kJ
Answer is: <span>
The reaction will not be spontaneous at any temperature.

<span>Gibbs free energy
(G) determines if reaction will proceed spontaneously.
ΔG = ΔH - T·ΔS.
ΔG - changes in Gibbs free energy.
ΔH - changes in enthalpy.
ΔS - changes in entropy.
T is temperature in Kelvins.
When ΔS < 0 (negative entropy change) and ΔH > 0
(endothermic reaction), the process is never spontaneous (ΔG> 0).</span>
Answer: One carrier interested in taxonomy is a veterinarian
Explanation:
Veterinarians as said, are interested in taxonomy. They are interested with animal organisms of all types with all species of animals. Hope this helps. Let me know if you need anything else.
Answer:
Elements: F, Cl, Br, I, At
Explanation:
Hi there,
When you are trying to find the valence electrons for an element, look at the last number of the electron configuration.
For example, if you want to find the number of valence electrons of Carbon (C), you notice that the electron configuration is<u> 2 - 4.</u>
We know that this element has four valence electrons because the last number in its electron configuration is 4.
For your question, simply find all of the elements that have the number 7 as the last number on its electron configuration on the periodic table.
Hope this answer was helpful. Cheers.
