An aqueous solution has a normal boiling point of 103.0°C. What is the freezing point of this solution? For water K b = 0.51°C and K f = 1.86°C/m.

B"hf and f-"  is the correct answer took the test on edgenuity and got it right     

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   

Well technically there are two correct answers b and d. but for you its probably b in general.good day sir/ma'am : ) (i know not gender)
