Balance this equation
__Fe(NO3)3 + _Ca(OH)2 -> _Fe(OH)3 +_Ca(NO3)2

2Fe(NO3)3+ 3Ca(OH)2->2Fe(OH)3+ 3Ca(NO3)2

Explanation:

My chem teacher taught us with a T-chart to hep us see how to balance equations better

  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-
