Two substances at different temperatures are brought together and allowed to reach thermal equilibrium. Substance A has a specific heat capacity that is two times that of substance B. The mass of substance B is four times the mass of substance A. Which statement best describes the final temperature of the two substances after they are allowed to reach thermal equilibrium

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.
