Professor X used 52g Fe and 44g of O2 to create some rust (Fe2O3). He produced 69.92g of Fe2O3.

Find the percent yield of his reaction given:

4Fe + 3O2 —> 2Fe2O3

answer; i believe that the correct answer is (a); a large rock being weathered by wind and rain;

  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-
