It's called a subscript, and in the formula for a substance, it tells you how many representative particles you have of that substance. If there is no subscript, it is understood to be 1, which means you only have 1 representative particle of that substance.
Examples: H2O, or water, means you have 2 hydrogen atoms and 1 oxygen atom.
Ca(NO3)2, or calcium nitrate, means you have 1 calcium atom, and 2 nitrate polyatomics (comprised of a total of 2 nitrogens and 6 oxygens.) A subscript outside a set of parentheses distributes to everything in the parentheses.

What information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction?
The information in a balanced chemical equation shows how many moles of a reactant are involved in a reaction is the number appearing immediately before the formula for the reactant in question in the chemical equation. This number is called a "coefficient".
Does a chemical formula describes a chemical reaction?
Yes, chemical equations describe chemical reactions. A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
A number placed in front of a chemical formula in a chemical equation is called?
In a chemical Equation ,The reactants are on the left side of a chemical equation and the products are on the right side.The number in front of a chemical formula in a chemical equation is called atoms. They should be a balancing number on both the sides.
What is a number in a chemical formula that tells the number of atoms in a molecule called?
The atomic number.
What law states that the number of atoms on the right of a chemical equation is equal to the number of atoms on the left of the chemical equation called?
This is the law of mass conservation.
What is a number placed in front of a chemical formula in a chemical equation called?
Coefficient. It generally corresponds to the number of moles of the molecule / atom under consideration.
What is a number added to an atom or molecule to help balance a chemical equation?
A coefficient.
What is the number of carbon atoms involved in the photosynthesis chemical equation called?
If you think to carbon dioxide the molecule CO2 has 1 carbon atom.

This is the law of mass conservation.
What is a chemical equation that shows the same number of each kind of atom on both sides of a chemical equation called?
Balanced
Two atoms linked together is called?
Any number of atoms joined together by means of chemical bonds is called a molecule. The number of atoms in a particular molecule varies.
What 2H2 means in chemical equation?
H2 is a hydrogen molecule made of two hydrogen atoms bonded together. The preceding two refers to the number of moles of H2 molecules in the chemical equation.
