Question

What is the final equilibrium temperature after you mix 10 grams of ice at 0 degrees C with 50 grams of water at 90 degrees C? I have posted my proffesor's solution I understand it for the most part but I'm confused on why in her solution she does the mass of ice times the specific heat of WATER times change in temp. Why does she use the specific heat of water and not ice?? I understand the rest of the problem but that is tripping me up
