a 2.75-l container filled with co2 gas at 25°c and 225 kpa pressure springs a leak. when the container is re-sealed, the pressure is 185 kpa and the temperature is 10°c. how many moles of gas were lost?

58 km per hour : d

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.
