What mass of ethanol will release 410.0 J of heat when it cools from 32.2◦C to 19.1◦C? The specific heat of ethanol is 2.44 J/g◦C. Units are required.

the product of the pressure and volume is also constant

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.
