A. Spring on the left will stretch more.

B. Spring on the right will stretch more.

C. Both springs will stretch the same distance.

D. One cannot tell which spring will stretch more

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.

  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-

the correct answer to this question is 2
