One use of CaCl 2 is to salt roads in the winter. The equation that describes the change in freezing point of a solvent due to a solute is Delta T f =I* K f * molality . How much would the freezing point decreas if a 3.23 molal (m) solution were achieved? (K f =1.86^ C/(mol/kg) for water and i = 3 for CaCl 2 )

Calculate the molarity of 48.0 ml of 6.00 m h2so4 diluted to 0.250 l .

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.

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.
