2. Consider the equation A + B --> AB. Can you think of another situation you have encountered (outside of this course) where a process in this general form
takes place?
3. Describe a chemical reaction that you have recently witnessed. How did you
know that it was a chemical reaction? What type of chemical reaction do you
think it was?

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.
