1. (0.5 point) Halifaxium is a transition metal that can form
ionic compounds. When in a compound
with sulfate, halifaxium takes on a +5
charge. What is the chemical formula for halifaxium (V)
sulfate?

INSTRUCTIONS: When inputting the
chemical name in CAPA make sure to:

1. Do NOT include any states, such as (s), (l), (g)
2. DO include (aq) after the chemical formula for
an acid, with no space between the chemical
formula and the state - example HF(aq)
3. List the elements and subscripts as you see them – example
Ag2C2O4 would be input at
Ag2C2O4
4. Acids should always list hydrogen first - example HF
5. Hydrates will use a period to represent the dot – example
Zn(CH3CO2)2•6H2O would
be input as Zn(CH3CO2)2.6H2O
2. (1 point) What is the molar mass of halifaxium (V) chloride
in g/mol?

INSTRUCTIONS: Input your answer
to TWO (2) decimal places in standard
notation (example: 1.23). DO
NOT input units in the box. If you include units the
response will be marked
as INCORRECT.
3. (0.5 point) An acid containing halifaxium has the chemical
formula HHaO4 and is named "halifaxic
acid". What is the name of the anion formed when the
hydrogen cation is lost?

INSTRUCTIONS: Choose one of the
following options.




a- halifaxo

b- halifaxic

c- halifaxous

d- halifaxiumite

e- halifaxate

f- halifaxite

g- halifaxide
