In a chemical formula what do subscripts mean?
In a chemical formula, the significance of subscripts is that it tells you how many atoms of a certain element are present in a structure.
An expression in which symbols and formulae represent a chemical reaction?
A chemical equation is an expression in which symbols and formulae represent a chemical reaction. It shows the reactants on the left side and the products on the right side, with coefficients to balance the number of atoms on each side.
What chemical are used to represent chemical substances such as compound?
Chemical formulas are used to represent chemical substances, composed of symbols and numerical subscripts representing the elements and their corresponding ratios in the compound. Common examples include H2O for water and CO2 for carbon dioxide.
What expression is used to represent the concentration of OH- ions?
pOH is the expression used to represent the concentration of OH- ions. It is calculated as the negative logarithm of the hydroxide ion concentration in a solution.
What is meant by term chemical formula?
A chemical formula is the "name" of the molecule of the substance. For example Water's chemical formula is H2O, it represent how many atoms of each element are involved. There are 2 hydrogen and 1 oxygen in the above example.

What does a formula tell you?
Chemical formulas are used to represent chemical compounds. It shows the component elements of the compound. Also it shows the ratios of the component elements.
The small number used to represent the number of ions of a given element in a chemical formula?
The small number used to represent the number of ions of a given element in a chemical formula is called a subscript. Subscripts are written to the right of the element's symbol and indicate the number of atoms or ions present.
What is the written notation used to represent the number of atoms of each element in a compound called?

What is used to represent chemical substances such as compounds?
Not all chemical formulas represent a compound. Chemical formulas that contain two or more elements represent a compound. Chemical formulas can also represent diatomic molecules, such as H2 or O2. Sulfur is represented by the formula S8.
Roman numeral for formula NaF?
Roman numerals represent numbers. They are used in chemical formulas to represent the valancy of transitional metals but as neither Sodium or Fluorine is a transitional metal there is no use for Roman numerals in the formula NaF.
Can an element be represented as a chemical formula?
Yes, an element can be represented as a chemical formula. Each element is identified by a unique chemical symbol, such as "H" for hydrogen or "O" for oxygen. Chemical formulas are used to represent the composition of compounds, which are combinations of elements.
