Samuel debe preparar una solución de pOH igual a 5,73. De las siguientes concentraciones de NaCl, ¿Cuál es la solución que debería tomar Samuel? Realiza para cada uno, el cálculo de pOH. a) 0,00184 M

b) 0,000184 M

c) 0,0000184 M

d) 0,00000184 M

The answer for this question is d. none of these

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
