Which of the following shows the path followed by nerve impulses in a reflex? a. motor neurons → interneurons in brain → sensory neurons b. sensory neurons → interneurons in brain → motor neurons c. motor neurons → interneurons in spinal cord → sensory neurons d. sensory neurons → interneurons in spinal cord → motor neurons

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

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.
