Answer:
C.) One mole of mercury
Explanation:
You can determine which has the greatest mass by identifying each of their atomic masses. The atomic mass represents the mass of an element per 1 mole.
Gold (Au): 196.97 g/mol
Mercury (Hg): 200.59 g/mol
Barium (Ba): 137.33 g/mol
In this case, one mole of mercury has the greatest mass.

Just because I never seen a white whale:)
Answer:
Vanderwaals forces
Explanation:
CBr4 is a nonpolar molecule, nonpolar molecules usually possess vanderwaals forces between their molecules as their main attractive force.
CBr4 is nonpolar because the tetrahedral arrangement of the C-Br bonds cancel out the individual dipole moments of each C-Br bond thereby making the compound nonpolar, hence the answer above.
Potassium chloride reacts with ammonium nitrate to give ammonium chloride and potassium nitrate.
This is a type of double displacement reaction. The balanced chemical equation can be represented as,
Total ionic equation for this reaction will be,
There is no apparent reaction as this reaction is not accompanied by the formation of a gas or a solid precipitate. We cannot observe any visual reaction as there is not net reaction taking place. All the ions remain as spectator ions.
