.An organic compound G has the following composition by mass: C = 64.88 %; H = 13.49 %; O= 21.63 % Oxidation of G using acidified potassium manganate(VII) gives H which is positive to both the 2,4-dinitrophenylhydrazine and Tollen's reagent test. Treatment of G with a concentrated acid forms J which decolourises bromine. J reacts with hydrogen chloride to give K. K undergoes alkaline hydrolysis to form L which is a structural isomer of G. L resists oxidation by acidified potassium manganate(VII) solution. (a) Give the name and structural formula for G, H, J, K and L.​

  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-
