You have a balloon that is inflated to 105kpa, with a volume of 2.2l, at a temperature of 295k. when you step outside into the cold winter weather, the balloon's temperature decreases to 279k. what is the volume, in liters, of the balloon while you are standing?

The law of gases volumen

v= 2.08 L

Explanation:

Using equations of gas:

P1= 105 kpa is constant because the ballon continue

So the volumen while is outside in liters is v= 2.08

  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 minerals.
