Please Calculate the number of milliliters of 0.544 M NaOH required to precipitate all of the Co2+ ions in 102 mL of 0.462 M CoBr2 solution as Co(OH)2. The equation for the reaction is: CoBr2(aq) + 2NaOH(aq) Co(OH)2(s) + 2NaBr(aq)

the answer is true. hope 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.
