The following reactions are all similar to those of the industrial chemicals. Complete and balance the equations for these reactions: (a) reaction of a weak base and a strong acid NH3+HClO4 (b) preparation of a soluble silver salt for silver plating Ag2CO3+HNO3 (c) preparation of strontium hydroxide by electrolysis of a solution of strontium chloride electrolysis SrCl2(aq) + H2 O(l)

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.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
