Argon gas is heated to 35 °C and then cooled to 10 °C. The gas is then brought back to its original state. Has the gas undergone an enthalpy change? Explain.

the answer would be c

hi my dude or dudette

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.
