Rule of Thumb for Cell Diagrams

[Emily Glaser 1F]

How should I go about writing the notation for a cell diagram. Can someone break it down for me because some of the things I see in solution manual confuses me

[Ryan Sydney Beyer 2B]

When writing cell diagrams, we are supposed to have the anodic compartment on the left and the cathodic compartment on the right. To go more into detail about the anodic compartment, the far left side is supposed to have the metal or solid electrode, right side of the anodic compartment is supposed to have whatever gaseous or aqueous things are present. All of the different phases are separated by a single vertical solid line. Then the anodic and cathodic compartments are separated by 2 vertical solid lines. The cathodic compartment has the same thing but with the electrode on the far right.

[Remi Lathrop 1G]

Sometimes the cell diagrams use comas instead of lines to separate two reactants, why is this? When do we use a solid line and when do we use a coma?

[Tasnia Haider 1E]

You use a comma when the ions or compounds are in the same state on the same side, and use a single line when they have different states.
