A block has 73 kg is being pushed and accelerated at rate of 10 m/s. what force is being applied to the block? A-730 N
B-7.3 N
C-7300 N
D-730 Kg

Here's the solution ~

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.
