The question is asking to give and states the formulas for the mercury compound and base on my research and further investigation, the answer would be HgSO, Li2S2O3 and <span>(NH4)3PO4. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications </span>
Depending on the size of the object, that system may describe it
in terms of inches, feet, yards, chains, rods, or miles.
<span>NaCl is poster-compound for ionic bonding. The bonds in NaCl have about 70% ionic character, making the bond highly polar. its overstatement to state that there is actual ion in NaCl with +1 and -1 charge but actual charge of Na and Cl is +1 and -1 ion, since Nacl exist as a network of highly charged particle and not discrete molecule, NaCl particle does not exhibit intermolecular forces.
Water molecule on other hand exhibit London dispersion force, keesom force, and hydrogen bonding.
The polar water molecule are attracted to the polarized Na and Cl atoms. This is what allow NaCl(s) to dissolve and ionize in water. Therefore type of attraction in NaCl is ion-dipole attraction.</span>
C not sure 100 percent but my best guess
