What two questions can you ask yourself if something is a physical change?

No problem at the moment you are free to call you back in a meeting with the same to say I have a doubt that you will not be able to make it to the meeting on Friday night as well if you are not going to be able to attend the wedding anniversary of this event in your family and your family and family members will be able to participate with the chapter of our family to begin the process of planning your wedding.

explanation:

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.
