Explanation:
Pumice is an extrusive igneous rock that is produced through volcanic activities.
A rock like pumice will pass through the rock cycle and be transformed to other rock types with time.
Pumice contains rich mafic minerals giving it that black appearance.
The consequences of this is that when the rock is acted upon by weathering elements, it is weathered to clay. A fine grained sediment. It will eventually be transformed to shale or claystone sedimentary rocks.
If is goes through the metamorphic path, a schist will form under conditions of high pressure and temperature. New minerals will grow and metamorphic transformation would be vivid.
Eventually, both sedimentary and metamorphic rocks can be subducted and will form the original melt again.

Explanation:
The same can be solve by using Nernst's equation
The Nernst's equation is:
![Ecell=E^{0}_{cell}-\frac{0.0592}{n}log\frac{[anodic]}{[cathodic]}](https://tex.z-dn.net/?f=Ecell%3DE%5E%7B0%7D_%7Bcell%7D-%5Cfrac%7B0.0592%7D%7Bn%7Dlog%5Cfrac%7B%5Banodic%5D%7D%7B%5Bcathodic%5D%7D)
For silver cell
n= 1
As both the compartments have silver nitrate solution,t the standard emf of cell will be zero.
Given
Ecell = 0.045
[Anodic compartment]= 1 M
Putting values
Taking antilog and solving
[AgNO3]=0.174 M
