Draw a structural formula for potassium 2-ethylbenzoate, showing the charges on the cation and the anion.

Cr(oh)3 -> cr(3+) + 3oh-

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
