What happens to solubility when the temperature of a solvent is increased.

The endotherdic energy raises that its breaks down the bond of the solvent which makes the solute-slovent interaction weaker

The answers is bad germs in their

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
