Question 2:
How can you tell which component (dry ice/acetonitrile) is positive or negative q?

I'm not sure exactly what you're asking, but I believe it's because of the phase. Since qdryice would go through sublimation and delta H is negative for sublimation (and at a constant pressure, qp = delta H)
