I dunno why, but I feel like the answer is supposed to be C. But Topscore says A is correct 😕

I didn't think there was such thing as a Cl^2- ion?

Or is it a typo??

Any help is greatly appreciated 😳

I think its supposed to be C.

If it says 'A' then I think it has to be a typo. I think the answer should be 'C'.

Agreed. Cl does not have a 2- charge.

Haha.. I saw this the other day. I don't like topscore... It's definitely supposed to be C.

I found another error in one of their gchem tests... It was a problem about finding the rate law when given the elementary steps of a reaction.
