If a balloon with a volume of 25.4 liters at a pressure of 1 atm is taken to the bottom of a 68 ft pool (34 ft of water= 1 atmosphere) how many atmospheres of pressure are now pushing on the balloon? What is the new volume of the balloon at the depth?

  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 answer is a for sure mark brainliest i had got this right on usatestprep
