These are just the dry cell and the lead-acid cell. They are the cells you studied.

Whilst you aren't expected to replicate that diagram, if you knew your cell well then you would know which is which and thus be able to infer it from your own knowledge.

Or you can use common sense, because a dry cell is literally a BATTERY and we all know what a battery looks like (cylinder with a head poking out on the +'ve terminal)


Also, by definition the positive terminal represents the cathode, and the negative represents the anode.

over here :S
Oh wow. Sorry it must've been that I got confused in what you said at the start. For some reason I saw things in reverse.

In that case I'm convinced you're right. What is the source of this question?

Can you send a picture of the isomers you drew?

The circuit is incomplete so no current can flow

Ah. In that case yeah I'm just convinced they're wrong. Jake's going to have his hands full with physics tonight so I won't bother bringing it up for now, but if he sees this he may be able to input.

In general, it won't work because you can't allow migration of ions. An exception is made when they're just one compartment (and not separated), which needs a bit more thought than the norm (see Jake's lecture slides I think it's there)

Note - Only true in GENERAL.

This Q seems pretty similar

Sorry, picture's too small.

Maybe download the ATARnotes app and then just directly upload the photo in the future


But these are the only ones I've found:
1,1-dichloro
1,2-dichloro
2,2-dichloro
1,3-dichloro

At least that past HSC question wasn't ambiguous
