Calculate the approximate initial boiling point (in oC) of a solution of 285 g of
magnesium chloride in 2.0 kg of water. The kb of water is (0.52°C/m)

C

Explanation:

The important thing to recognize here is that sodium chloride is an electrolyte, which means that it will dissociate in aqueous solution to give sodium cations,  

Na

+

, and chloride anions,  

Cl

−

NaCl

Explanation:

gravity causes stares to cluster i think so

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
