Kari has five different-shaped containers that all have the same volume. She will fill each container with water at the same rate to find the amount of time it takes to fill each to a certain height. What is the dependent variable in Kari's experiment?

the answer is c

tell me if wrong

the answer is d.) potassium

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.
