in complete sentences)
1. how do your results from the flame test provide support for quantized energy levels? explain your
answer. it

Explanation:

From flame test, one can observe different colors in the procedure. This light given off corresponds to the excitation of electrons by the addition of energy from one energy level to another.

From Bohr's model of atom:

  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-
