Mezclamos 0.08 moles de ácido cloroacético (ClCH2COOH) y 0.04 moles de
cloroacetato sódico (ClCH2COONa) en 1.0 L de agua (pKa = 2.865).
a. Calcula el pH
si. Calcula el pH usando las formas formales (actividades). Tener en
cuenta el aporte de los protones (apartado a) en el cálculo de la fuerza iónica.
C. Hallar el pH de una mezcla preparada disolviendo los siguientes compuestos
en un volumen final de 1L: 0.08 moles de ClCH2COOH, 0.04 moles de
ClCH2COONa, 0.05 moles de HNO3 y 0.06 moles de NaOH

catya that's not even a b or c

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.
