Write the product of the following sequence of reactions. Indicate stereochemistry where appropriate. When a racemic mixture is formed, you must draw one enantiomer by drawing dashes or wedges and write RACEMIC in the box.

  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-

particle   p is an electron and particle q is a neutron

i dont know the answe

50.23 i believe is correct but don't quote me on that.
