It usually represent the amount of atoms in a molecule, i.e.
Na2CO3 + 2HCl --> 2NaCl + CO2 +H2O
So, in the first compound, there are 2 sodium atoms, one carbon atom and 3 oxygen atoms. In water, there is one hydrogen atom and 2 oxygen atoms..

Do subscripts represent the relative mass of each type of atom in the compound?
Yes!
What chemical refererence shows the relative number of atoms of each element in a compound?
It is important to know the relative number of atoms of each element in a compound for the chemical composition.
New compounds made during chemical reactions are?
1. A chemical equation is a concise shorthand expression which represents the relative amount of reactants and productsinvolved in a chemical reaction. The skeleton equation indicates that two hydrogen atoms react with two oxygen atoms on the reactant side of the equation.
What is molecular mass?
the relative molecular mass or molecular weight of a compound is the mass of a molecule of the compound relative to the mass of a carbon atom taken as exactly 12.
What does a chemical formula communicate?
A chemical formula shows the composition of a substance. It shows the elements present and their relative numbers. There are several types of formula which give specific types of information, but that's the basics.
Do subscripts represent the relative mass of each type of atom in the compound?
Yes!
How does the chemical formula of a compound relate to the relative number of atoms in the compound?
Chemical formulas consist of chemical symbols and numbers. The symbols represent the elements in the compound. The numbers indicate the quantity of atoms of each element in the compound.

How do you express relative amounts of each element in a compound?
The subscripts indicate the amount of each element present in the compounds in a chemical equation. For example, H2O indicates that each molecule of water contains two atoms of hydrogen and one atom of oxygen. The lack of a subscript is understood to mean the number one. For an ionic compound, such as magnesium chloride, MgCl2, the subscripts indicate that each formula unit contains one magnesium ion and two chloride ions.
Can subscripts in a chemical formula be fractions?
The Subscripts in a Chemical formula explain how the atoms in that compound are chemically bonded. As a fraction of an atom cannot bond, the subscripts cannot be fractions. Coefficients, however which go before a chemical formula in chemical equations may be fractions. This is because they explain the ratio of the number of moles of each species required for the reaction and it is possible to have a fraction of a mole of something.

The chemical formula of a compound does not indicate?
The chemical formula of a compound does not indicate the way that elements are joined in the compound. Chemical formulas tell you the identity of the elements in the compound and the relative proportions of the elements.
What is an empirical formula?
The chemical formula in which the subscripts are given in the smallest ratio.
What shows the relative number of atoms of each element in a compound.?
It is important to know the relative number of atoms of each element in a compound for the chemical composition.
What does the positive and negative symbols represent in energy source?
Relative charge. (And/or relative voltage.)
