P-xylene, c8h10, has an enthalpy of fusion of 158.3 j g-1 and its melting point temperature is 13.2°c. how much heat is required to transform 115 g of solid p-xylene at 13.2°c into liquid p-xylene, also at 13.2°c?

What effect does nuclear radiation have on atoms?

Which characteristic of water it form droplets? a. low specific heat b. nonpolar structure c. high surface tension d. ability to dissolve substances

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.
