Ayuda por favor...En tanque 50 litros hay 42 kilogramos de vapor de agua a la presión de 20.5 atm absolutas y temperatura de 522 K, después de enfriar el tanque a 210 Kpa
parte del vapor se condensa. Para fines de cálculo suponga que el tanque no
absorbe energía. Determine cuanto de enfriamiento se requiere y cuál es la
temperatura final en el tanque​

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.
