Asample of argon (ar) gas occupies 65.0 ml at 22.0°c and 725 torr. what is the volume of this ar gas at stp? enter your answer in the provided box.

Explanation:

The given data is as follows.

      = 65.0 mL = 0.065 L (as 1 ml = 0.001 L),      

      = = (22 + 273) K = 295 K,

      = 725 torr = 0.954 atm           (as 1 torr = 0.00131579 atm),

      = ?,   = 273 K,

      = 1 atm

And, according to ideal gas equation,

            = 0.0574 L

As, 1 L = 1000 ml. So, 0.0574 L = 57.4 ml.

Thus, we can conclude that the volume of this Ar gas at STP is 57.4 L.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements
