Plz will give which statement describes what happens when bret runs up a flight of stairs? his kinetic energy is destroyed. his potential energy decreases. his kinetic energy is converted into potential energy. his potential energy is converted into kinetic energy.

his kinetic energy is converted to potential energy

im pretty sure its b

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.
