Se mezclan 100 ml de CH3COOH al 0,05 F con 115 ml de una solución de CH3COONa al 0,07 F (Ka = 1,8x10– 5). Determine: añadir: a) 20mldeHClal0,23F
b) 15 ml de NaOH al 0,115 F
c) 25mldeNH3 al0,02F
d) Cuál es la variación de pH al añadir 22 ml de CH3COOH al 0,2 F

it is a good conductor

explanation:

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
