You have made use of the Le Chatelier principle in this lab. Explain how the Le Chatelierprinciple is used to help formation of the product in the reaction you performed in this lab, AND, WHY it isnecessary to make use of the Le Chatelier principle to help this reaction to "go".

CHALLENGE ACCEPTED!

Explanation:

Basically, Le Chatelier's principle is the equilibrium law used to predict the effect of a change in conditions on some chemical equilibra. It is often used to increase the yield of reactions.

  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-
