7.731×10^5

Explanation:

77.31 can not be because the first variable in the scientific notation must be a value between 0-10

thus, the number will be 7.731

77.31×10^4=773100

if the number is 7.73100 then we move the decimal place to the end and count how many places to the right it took

for this instance, the decimal point moved 5 places to the right

therefore, the answer is 7.731×10^5

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.
