A solid sample of Zn(OH)2 is added to 0.400 L of 0.550 M solution of HBr. The solution that remains is still acidic. It is then titrated with 0.500 M NaOH solution, requiring 165 mL of the NaOH solution to react completely. What mass of Zn(OH)2 was added to the HBr solution

There are no metaphors.

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
