Mixing baking soda and vinegar is an example of an endothermic reaction. This means... A. baking soda and vinegar are products in this reaction.

B. energy is taken in during the chemical reaction.

C. energy is released during the chemical reaction.

D. there is no change in energy during the chemical reaction.

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.
