Answer:

#"HgBr"_2"# is mercury (II) bromide.

Explanation:

Since bromide anions always have a #1^(-)# charge, and there are two bromide ions in the formula, the overall charge for the bromide part of the compound is #2^(-)#. This compound is neutral, which means that the mercury cation must have a #2^(+)# charge, and is therefore the mercury (II) cation.

Therefore, #"HgBr"_2"# is mercury (II) bromide.

If you go to the following site, you will see that #"HgBr"_2"# has many names, but usually it is called mercury (II) bromide. https://pubchem.ncbi.nlm.nih.gov/compound/24612#section=Top
