You place a balloon in a closed chamber at standard temperature and pressure (STP) . You triple the chamber pressure. What happens to the balloon?
a) The volume stays the same.
b) The temperature must also change for the volume to change.
c) The volume decreases to one-third of its original volume.
d) The volume increases to three times its original volume.

C

Explanation:

h let me think

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
