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 do you put parentheses around a polyatomic ion?
Parentheses around a polyatomic ion in a chemical formula indicates that more than one of that ion is present in the compound. This notation helps clarify the chemical formula and the ratio of elements in the compound.
How should more than one polyatmotic ion be indicated in a chemical formula?
In a chemical formula, more than one polyatomic ion is indicated by using parentheses around the ion and then placing a subscript outside the parentheses to denote the number of that ion present. For example, in the case of calcium nitrate, which contains two nitrate ions (NO₃⁻), the formula is written as Ca(NO₃)₂. This notation clarifies that there are two nitrate ions associated with each calcium ion in the compound.
What is the chemical formula of pearl ash?
You can get a 3/4hp garbage disposal replacement for around $200. It will cost you around $250 for a plumber to install the unit. You should shop around for a good plumber at the lowest price in your area. It isn't a project you should do yourself unless you are fully competent.
What does NH4 stand for in chemistry?
The NH4 asked about is the amonium ion, and it's written NH4+ to indicate it has a positive charge (+1). It's a cation. Wikipedia has more information on this chemically significant polyatomic ion, and you'll find that a link to that post is provided below.
how should you indicate that there are multiple polyatomic ions in a chemical formula?

How should more than one polyatomic ion be indicated in a chemical formula?
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.

How do you use the term chemical formula in a sentence?
"The chemical formula for rayon was discovered around 1855." "Alfred Nobel, for whom the Peace Prize is named, developed the chemical formula for dynamite."
How do you enforce precedence in the formula in cell E1 by adding parentheses around the arguments in the addition operation?
=(b1+c1+d1)/3
What is the chemical formula of endosulfan?
The chemical formula of endosulfan is C9H6Cl6O3S. Endosulfan is used in agriculture around the world to control insect pests such as Colorado potato beetles, cabbage worms, leafhoppers, and whiteflies.
What other symbol is used for parenthesis in graphing inequalities?
In graphing inequalities, brackets ([]) are often used in conjunction with parentheses to indicate whether endpoints are included or excluded. Parentheses signify that the endpoint is not included (open interval), while brackets indicate that the endpoint is included (closed interval). For example, an inequality of x < 3 would be represented with a parenthesis around 3, while x ≤ 3 would use a bracket.
Can you put parenthesis around addition before multiplication?
Yes, you can put parentheses around addition before multiplication, which will affect the order of operations. For example, in the expression (2 \times (3 + 4)), the addition is performed first, resulting in (2 \times 7), which equals 14. Parentheses indicate that the operations inside them should be completed first, regardless of standard order of operations.
When a sign is not written between two numbers how do you calculate that?
If there are parentheses around the numbers (two parentheses for each number) multiply them.
