Naomi is testing the different properties of an unknown solid. Her results are located in the chart. Which statement describes the chemical nature of the bonding in the substance?

When chilled, the atoms rolled over each other while still staying together, causing a lower temperature.
When heated, the valance electrons increased their speed and transferred the heat from electron to electron.
When treated with light, the atoms rolled over each other while still staying together, causing a reflection of light.
When treated with an applied force, the valence electrons increased their speed and transferred the change from electron to electron.

  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-

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
