Strontium compounds are often used in flares because their flame colour is bright red. One industrial process to produce low-solubility

strontium compounds (that are less affected by getting wet) involves

the reaction of aqueous solutions of strontium nitrate and sodium

carbonate. Write the balanced chemical equation, total ionic equa-

tion, and net ionic equation for this reaction.

  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-

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
