Sakura tested the pH of several solutions. Which substances are acidic? Check all that apply. Cola-flavored soda: 2. 6 cranberry juice: 2. 9 dish soap: 7. 3 pickle juice: 5. 5 seawater: 8. 0 lye soap: 13. 0.

The correct answer is c. orbital shape. "the angular momentum quantum number l describes the shape of an orbital. it corresponds to each orbital type, i.e. (0,1,2,−1)=(s,p,d,f,g,"

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   

The answer to this is the 3rd choice!
