Hypobromite; Bromite; Bromate; Perbromate

What must be true for a saturated solution?

No solutes can be dissolved upon addition

What is the definition of first ionization energy?

The energy it takes for one valence electron to be moved from the atom

CF4: Are C-F bonds in this molecule polar?

Yes

CF4: If yes for polar, to which end does the negative end of dipole moment go to?

F

CF4: Is the molecule overall polar?

No, because the dipoles cancel out.

H2S: Are the H-S bonds in this molecule polar?

Yes

H2S: Is the answer is yes to polar, to which end does the negative end of the dipole moment point to?

S

H2S: Is the molecule overall polar?

Yes

SCl6: Are S-Cl bonds in this molecule polar?

Yes

SCl6: If the answer is yes to polar, to which end does the negative end of dipole moment point to?

Cl

SCl6: is the molecule overall polar?

No
