liquid and gaseous states in a cell diagram

If we have different states on one side of the redox reaction, do we list them with a comma in the cell diagram or a line separating them? Also, is there a specific order we have to follow when listing things in cell diagrams (besides the electrodes being on the outsides)?

When you list substances with different states, you separate them with a line. The only time you use a comma is when they share the same state, such as if they're both aqueous.

Like you said, electrodes should be on the outside. Another thing to keep in mind is that you should place the substance being oxidized right next to the salt bridge (a.k.a the double line) - it doesn't matter which side the substance is on.

In a cell diagram, the single line | means that two species in different phases are in contact, the comma separates species of the same phase, and the double line signifies the salt bridge.

To continue the answers above, remember to use a single line when referencing a porous disc versus the double line used for a salt bridge.
