6) When 5.00 grams of ammonium chloride, NH. Cl, is added to 100 ml of water the temperature drops by
4.2°C how much would the temperature change if 10.0 grams is added to 1000 ml. of water?
7) 2.71 grams of a fuel was burned releasing 4.10 k) of energy into some amount of water. The water
changed from 22.2 °C to 53.1 °C. How much water was heated?
8) A 125.0 gram sample of a metal, X, was heated to 400.0 °C and placed onto a 1.000 kg block of ice at
0.0°C. Some of the ice melted, but after the metal and ice reached thermal equilibrium the temperature
of the metal, ice and liquid water remained at 0.0°C. If the specific heat of the metal was 0.245 1/g°C
calculate the heat lost by the metal?

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
