An ingredient list for a compound that uses atomic symbols and subscripts?
empirical formula or molecular formula
What do you use to balance charges when writing a molecule's formula?
Because the chemical formula of the molecule must be neutral.
A chemical formula includes the symbols of the elements in the compound and subscripts that indicate what?
The number of moles in each element
What is the sum of all charges in a formula for an ionic compound?
Zero is always the sum of all charges in a formula for a neutral compound, whether ionic or not.
How are chemical formulas written do they use superscripts or subscripts?
Chemical formulas are written with the chemical symbol of each element followed by a subscript. If no subscript is written, it is understood to be 1. In a molecular formula, the subscripts indicate the number of atoms of each element that are present in one molecule. In a chemical formula for an ionic compound, the subscripts represent the lowest whole number ratio of ions in the compound.

The actual molar ratio of elements in a compound as expressed by the subscripts in a formula is expressed in what?
molecular formula

What is the total number of atoms of carbon in the formula K3FeCN6?
In chemical formulas, carbon atoms are denoted with the symbol C. Subscripts and superscripts denote the number of carbons. Since there is only one C and no subscripts or superscripts, the compound stated contains only one carbon atom.

What is a method for representing a compound with atomic symbols and subscripts that shows the elements and the number of atoms of each element that combine to for a compound?
a chemical formula
The molecular formula mass of this compound is 210 amu What are the subscripts in the actual molecular formula Enter the subscripts for C H and O?
Element Element's atomic massC : 12H2 : 2(hydrogen's atomic mass is 1 but remember there are two)O : 16Add all the elements atomic mass and then divide the molecular mass by it. After that you only need to multiply all the subscripts of each element to find your answer.12+2+16=30240/30=88(CH2O) = C8H16O8
Why does oxygen not have a subscript?
Oxygen does not have a subscript since it is an element. Subscripts are usually found in the chemical formula of a compound and not an element.
What is the empirical formula for magnesium oxide?
MgCl2 is the correct formula, or two atoms of Cl for each 1 atom of Mg. You could also say 2 moles of Cl atoms for every 1 mole of Mg atoms. The empirical formula should be written with the subscripts in lowest whole number terms. Note that this formula is consistent with the fact that an Mg cation is Mg+2 and a Cl anion is Cl-1. Given these charges, a formula of MgCl2 is the one with the smallest whole number subscripts that will allow the charge of the compound to be zero. See related question below for more details on how to find empirical formulas.

What is the empirical formula for a Compound with the molecular formula C16H12CI2O2?
The formula as written, including a capital "I", is already an empirical formula, since it shows a total of 7 carbon atoms and none of the other subscripts is integrally divisible by 7. However, the formula may have been intended to be written C16H12Cl2O2. In that instance, all the subscripts can be integrally divided by 2 to given an empirical formula of C8H6ClO.
