A volume of 40.0 mL of a 0.320 M HNO3 solution is titrated with 0.340 M KOH. Calculate the volume of KOH required to reach the equivalence point

The answer is the first option just took the test

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
