g unknown diene produce a chromatogram with 3 distinct peaks. From the determination of peak area, you find that the percent compositions represented by the peaks are: peak A is 26.66 percent, peak B is 60 percent, and peak C is 13.33 percent. If the largest peak in the chromatogram corresponds to the diene, how many moles of diene are in the crude oil

take a better picture and ill do it

  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-
