Density because a substance always has the same density, but mass can be different and volume depends on mass
Hydrocarbons do not dissolve well in water because they are nonpolar. On the other hand, salts dissolve much better. This means that benzene and hexane will not significantly dissolve, while the rest will. So the compounds that will dissolve in water are: potassium iodide, lithium chloride, and sodium bromide.
Adding heat to a system can encourage or increases a chemical reaction.
<h3>Change that can encourage a reaction</h3>
Increasing the temperature of a process, increase occurs in the average speed of the reactant molecules and we know that when more molecules move faster, the more number of molecules reacts with other molecules which results in faster formation of products.
In conclusion, adding heat is the right option.

Answer:
Multivalent Ionic
Explanation:
The type of bond formed between the atoms of two elements can easily be deduced from the magnitude of electronegativity difference between the two bonding atoms.
A summary of electronegativity differences and corresponding types of bonds are shown below as adapted from chemlibretexts, where Δχ is the difference in electronegativity ;
ionic if Δχ ≥ 2.0
polar if 2.0 > Δχ > 0.5
nonpolar if 0.5 > Δχ
To determine the type of bond between Hg and F. Hg has an electronegativity of 2 while F has an electronegativity of 4. the difference in electronegativity (Δχ) is 4 - 2 = 2
This corresponds to a multivalent ionic bond because mercurous ion is the
Hg2^2+ ion and this leads to the formation of Hg2X2 (mercury I fluoride).
