Nikki and Lisa wanted to see if different size wheels made their skateboards go faster. They always used the same course. Their results are shown in the table below.

Which of the following conclusions is supported by Tara's and Lisa's data?
Wheel size does not affect the speed of a skateboard
Sateboards with small wheels move faster.
Sicateboards with big wheels move faster.
What the wheels are made from has more of an effect than their size.

have a great day because if you dont you and i will be sad

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.
