Determine, in order, the number of valence electrons that must be considered for the three compounds CO2, CH3Cl, HCN.
   
 a.
10, 14, 14
 b.
10, 14, 10
 c.
14, 26, 14
 d.
16, 14, 10
 e.
22, 26, 14


How are the pressure and the absolute temperature of a gas related for a given number of moles at constant volume?

 a.
They are exactly opposites.
 b.
They are not related.
 c.
They are directly proportional.
 d.
They are indirectly proportional.
 e.
Not enough information given to determine.



    
If, at constant pressure, the absolute temperature of a flask equipped with a moveable piston is reduced to half its original absolute temperature, what must be the new volume?
   
 a.
1/4 the original volume
 b.
1/2 the original volume
 c.
two times the original volume
 d.
four times the original volume
 e.
equal to the original volume
