Which state of matter contains the most energetic particles? a. gas b. solid c. liquid d. plasma

Plasma because it is a charged gas and the molecules are more free to move in a gas state.

Option (D) is the correct answer.

Explanation:

Plasma is the hot ionized gas in which there are equal number of negatively charged electrons and positively charged ions.

Being hot, there will be more kinetic energy within its molecules. As a result, there is rapid and continuous motion of particles.

Thus, we can conclude that plasma is the state of matter which contains the most energetic particles.

  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-
