A gas can move around freely while a solid is hard and can’t move around freely
Since I don't have the diagram I'm going off my best estimate and the flow of the positive and negative charged protons and neutrons create a flow of energy when collided through a circuit or in this case the wire
Low electron affinity and large atomic radius
Metallic character decreases across a period (from left to right) and increases down a group.
Electron affinity increases from left to right within a period. This is caused by the decrease in atomic radius. Electron affinity decreases from top to bottom within a group. This is caused by the increase in atomic radius.
3.6 moles 
required when each quantity of reactant completely reacts.
The ratio of the mole quantities of any two compounds present in a balanced chemical reaction is known as the mole ratio. A reaction's product yield can be predicted using mole ratios, as can the amount of reactant required to produce a specific amount of result.
The balanced chemical equation is :
(l) → 
(g) + 
(g)
Given is = 2.6 mol 
As we see, 3 moles of reacts with 4 moles of .
Therefore,
n( ) = n( ) × 
n( ) = 
n( ) = 3.6 moles.
Therefores, 3.6 moles required when each quantity of reactant completely reacts.
