Astudent is using a copper strip and a strong chlorine solution in her experiment. which of these is a chemical property of one of her materials?

a.) density of the copper strip
b.) reactivity of the copper strip
c.) odor of the chlorine solution
d.) color of the chlorine solution

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.
