Lesson Question: What is the effect of
pressure on the volume of a gas?
To answer this question, you used weight to
change the
of the gas and
measured the
resulting changes to the gas's

a polar bond is formed when electrons are shared unevenly between atoms

gas

explanation:

smoke is the matter of a gas

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.
