Given the following balanced equation, which is NOT a correct conversion factor? 4 NH3 + 5 O2 → 4 NO + 6 H2O

1. 18.02 g H20 = 1 mol H2O

2. 5 mol O2 = 4 mol NO

3. 1 mol NH3 = 17.03 g NH3

4. 5 mol O2 = 32.00 g O2

  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-
