Midterm 2016 Q2
My question is why is the change in state of dry ice not included in the calculations for q?

If you look closely at the question... it says "acetonitrile BEFORE the acetonitrile begins to freeze", so you wouldn't need to include the heat required to change the acetonitrile from liquid to solid. Hope I helped!

Yes. The question doesn't give you any information about when dry ice sublimates so you'd assume it wouldn't change states during the process.
