A sample of gas has a volume of 100.0 L at 135 Celsius. Assuming the pressure remains constant, what is the volume of the gas if its temperature decreases to 72.0 Celsius?

- decrease the number of plants and animals living in the water.

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.
