9. You are an oceanographer taking measurements to predict whether this year will be an El Niño, a La Niña, or a normal year. (15 points) A. What are three instruments you will use? (3 points)

B. What measurements will each of these instruments take? (6 points)

C. What measurements would you expect to collect during an El Niño year and a La Niña year? (6 points)

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.
