  1. Yes, A is correct. C is worded funny and I don't know what it means but it could be true depending upon how it is interpreted.

    in our notes for strengths of acids and bases it says that you could add a strong/weak acid with a strong/weak base and it will give you a low, medium or high delta h. so wouldn't acids and bases be related to thermochemistry?
