A combustion analysis is a technique to find the the empirical formula of compounds. In a combustion analysis experiment, 0.8657 g of an organic compound containing only carbon, hydrogen, and oxygen is burned in oxygen, forming11.190 g of CO2 and10.3248 g of H2O. What is the empirical formula of the compound

- decrease the number of plants and animals living in the water.

  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-
