f the hot solution containing the dissolved benzoic acid is immediately placed in an ice bath, what would be the effect on recrystallization of benzoic acid.

hello your question is incomplete below is the complete question

 What effect would each of the following have on the success of the recrystallization of benzoic acid from hexane?

The hot solution of the benzoic acid in hexane is immediately placed in an ice bath.

answer :  The benzoic acid will start crystallizing almost immediately

Explanation:

The effect of placing a hot solution containing dissolved benzoic acid immediately in an ice bath on recrystallization of benzoic acid from Hexane is that the benzoic acid will start crystallizing almost immediately and this is because  it is a polar compound, and it has a high solubility in hot hexane,

After been cooled off it will recrystallize again.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
