Murrr4er [49]
5C₂ + 4SO₂ ------>  2CS₂  +  8CO

mole ratio of C₂  :  CS₂
                 =   5   :    2

∴ since C₂ contains 8 moles 

  then CS₂ contain   ( \frac{8}{5} )  *  2  moles
                            
                             =  3.2 moles

Answer:

The warmer, lighter air rises, bringing cooler, heavier air to low altitudes.

Air at higher altitudes doesn't have as much air weighing down on it from above.

Explanation:

In short - air pressure is the result of the cumulative force that air molecules act on objects below them due to Earth's gravity. The higher the altitude, the less air molecules there are to act a force below them, and therefore, there's less air pressure at higher altitudes.
