Why do you think it wouldn't be? Have you learned about acid anhydrides?

The reason it's one isomer that reacts and not the other is that only one has the COOH groups in the correct orientation

Regarding the product, the OH group of one of the COOH groups attacks into the other carbonyl, with loss of the other OH Try drawing out the mechanism and hopefully that makes sense

What type of mechanism is this called? I can't find it in the textbook 😞

I don't know about the 'type' of mechanism, it's just basic nucleophilic attack of the nucleophilic OH into the electrophilic carbonyl... Perhaps try not to focus too much on just memorising the examples given in the textbook, learn to apply the general principals to different situations

You need to draw the carbon atoms for a displayed structure.
