One reason is that the composition of a polyatomic ion is fixed, just as that of a compound is fixed. If more than one polyatomic ion is present in an ionic compound, the use of parentheses allows a subscript to be used after the right parenthesis to designate the number of ions just as such subscript is used to designate the number of atoms in a compound.
What else can I help you with?
how should you indicate that there are multiple polyatomic ions in a chemical formula?
put parentheses around the atoms in the ion and then add a subscript - apex
What is the chemical formula for the oxygen we breathe?
The chemical formula for the oxygen in the air is O2, where the 2 should be a subscript.
What is the condensed formula for acetic acid?
The chemical formula for acetic acid is CH3COOH. It should be noted that acetic acid is the same as ethanoic acid.
What is the chemical formula for lead 2 perbromate?
If this compound exist, the chemical formula should be Pb(BrO4)2.
Chemical formula for ironIII oxalate?
The formula of iron(III) oxalate is C6Fe2O12.
How should more than one polyatomic ion be indicated a chemical formula?
More than one polyatomic ion should be indicated in a chemical formula by putting parentheses around the atoms in the ions and then adding a subscript.

Why it is appropriate to group a polyatomic ion in parentheses in a chemical formula if more than one of that ion is present in the formula.?
Yes. PO4(3-) Phosphate, for example. Mg3(PO4)2 Why should be apparent. Mg2PO42 would be very confusing.

Write the formula of decane?
The chemical formula of decane is C10H22.
What is the chemical formula for Ca S?
CaS is the chemical formula for calcium sulphide. NB The elemental letters should NOT be separated by spaces. 'Ca S' is incorrect. I should be written as ' CaS'.
What is the chemical formula for arcylamide?
The chemical formula for arcylamide is censored by the government since acrylamid is a dangerous substance. You should not try to find it because it is illegal.
Chemical formula for ironIII oxalate?
The formula of iron(III) oxalate is C6Fe2O12.
What is the formula for aluminum phosphate?
You should try to study these formulas because they are not to difficult. Aluminum is a metal. So... you should first know that it is an ionic bond. Ionic bonds do not have prefixes, so you don't have to worry about adding them. Phosphate is a polyatomic ion. That means it has it's own "special formula." (Which you should study!) So. . . It should look like this ----------> Al PO4 Btw the 4 is below the O, not beside it.
