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 )

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

the answer is b. dilution
