Answer:
Mercury is the one that is closest to the sun
The delta G for the dissociation is 87,865 joule/kg.
The process is non-spontaneous because the value of Gibbs free energy is positive.
<h3>What is dissociation?</h3>
The breaking up of a compound into a simpler form that can be recombined under other conditions.
Given,
H = 145 kJ
Delta S = 195 J/k
Determining the G using the following process:
G = H -TS
G = 87,865 Joules/K
Thus, the value of Delta G is 87,865 and the process is non-spontaneous.

Explanation:
The elements in group form univalent positive ions and element in group 17 form univalent negative ions. Hence, when a group 1 element reacts with a group 17 element, a compound of the sort MX is formed. Hence, when a group 1 element reacts with bromine, a salt is formed with the general formula MBr.
Elements of group 1 are highly electro positive metals. They react with water to form the metal hydroxide and release hydrogen gas. Hence, when group 1 elements react with water, hydrogen gas is released.
A group 1 element forms a univalent positive ion while a group 16 element forms a divalent negative ion. Hence, when a groups 1 element reacts with oxygen, the compound formed must have the general formula M2O.
The reactivity of group 1 metal increases down the group hence Cs is the most reactive group 1 element.
Lithium displays a slightly different chemistry from other group 1 elements because of its small size.
Outside, because there is more space for it to go, and there is nothing stopping the water from going straight up into the sky.
