(a)
Interpretation:
The formula of the ionic compound calcium bromide has to be written.
Concept Introduction:
Rules for writing a formula from the name of an ionic compound:
The charge on the cation and anion is determined.
For metals with variable charge, the Roman numeral gives the charge of the cation.
For metals with fixed charge, the name of the cation is written first, followed by name of the anion.
The charges are balanced and the formula of the cation is written first and the subscripts are used to show the number of each ion needed to have zero as overall charge.
(b)
Interpretation:
The formula of the ionic compound copper (I) iodide has to be written.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
The formula of the ionic compound ferric bromide has to be written.
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
