Suppose of nickel(ii) bromide is dissolved in of a aqueous solution of potassium carbonate. calculate the final molarity of bromide anion in the solution. you can assume the volume of the solution doesn't change when the nickel(ii) bromide is dissolved in it. be sure your answer has the correct number of significant digits.

you need to have a picture of the atom that way we can answer it

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.
