c.- ¿Qué cantidad de solvente será necesaria para preparar una solución al 28%m/m empleando 14g de hidróxido de sodio (NaO)?​

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

bcde is the incorrect answer it is a

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.

the correct answer to this question is 2
