Adermatologist prescribes drysol as a treatment for excessive underarm sweating. drysol contains 15 g of aluminum chloride hexahydrate in 84 ml of an alcohol base. what is the final strength of drysol?

Drysol is a mixture of aluminum chloride hexahydrate and an alcohol base.

Mass of aluminum chloride hexahydrate = 15 g

Assuming the density of alcohol base to be 1 g/mL

Mass of alcohol base =

Total mass of the mixture = 15 g + 84 g = 99 g

Mass % of the mixture =

= 15.2 %

  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-
