What the would the freezing point of a solution that had 186 grams of NaCl dissolved in
4.5 kg of water?
Krwater = 1.86°C/m

Man i dont know this answer

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   

Ok so co(g) is not pronoused that. the only clue is that youpronouse it the oppisote way.
