Carbon disulfide is an important industrial solvent. It is prepared by the reaction of carbon (called coke) with sulfur dioxide. Carbon monoxide is also produced (as a byproduct) of this reaction.
(a) Write the equation that correctly demonstrates this reaction and balance it.
(b) How many moles of carbon are needed to produce 45.90 moles of carbon disulfide?
Please show work for the problem. Thanks!

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.
