A scientist performed an experiment to learn how the thickness of a piece of wood affects its ability to support weight without breaking. The scientist prepared three different pieces of wood and applied weight until they broke. The results are shown in the table below. Thickness of Wood Breaking Weight 1 cm 15 kg 2 cm 29 kg 3 cm 42 kg Which variable is intentionally controlled by the experimenter? A. The type of scale used to measure the weight O B. The thickness of the wood O C. The breaking weight D. The number of pieces of wood

your answer is c) plasma

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.
