Jimmy claims that the Earth’s rotation takes longer than the Earth’s revolution. Do you agree or disagree?

I disagree, because earth rotation on its axis causes day and night, on the other hand the its revolution on the orbit around the sun causes seasons. One Rotation would means one day has completed, and one revolution would mean that one year has completed. Therefore, it's obvious that Earth's revolution takes longer than the rotation.

I hope that helps...

  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-

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
