A chemical reaction under specific conditions will follow an equation describing in what ratios the reactants combine to form the products. Due to the conservation of mass principle, there must be the same amount of each atom on both sides of the equation. For example when hydrogen gas is burned in pure oxygen the reaction equation is as follows:
2H+ + O2- = H2O
Here we can see that due to the charge on a hydrogen atom being positive one and an oxygen atom being negative 2, two hydrogen atoms must combine with one oxygen atom in this specific reaction. Note that there are the same amount of hydrogen and oxygen atoms on both sides of the equation.
This applies to any chemical reaction. If you need to know how many molecules of reactant are used, check the reaction equation.

What information in a balanced chemical reaction shows how many moles of a reactant are involved in the reaction?
The coefficient (not a subscript or superscript) placed immediately before the formula of the reactant in the equation shows how many moles of a reactant are involved in the reaction. If there is no explicit coefficient, a value of 1 for the coefficient is assumed. The coefficient in front of the molecule tells its relative number of moles.

How can balenced equations be used to calculate the volume of gases formed in chemical reactions?
The coefficients in a balanced chemical equation shows how many moles of each reactant is needed in order for a reaction to take place. After determining how many moles of each reactant is required, you would convert it to grams to calculate how much of each reactant is needed to form a given amount of product in a chemical reaction.
What part of the chemical equation tells the number of atoms of each element?
That depends on the nature of the reaction. For a typical reaction, it will be the subscript following the symbol of the element multiplied by the coefficient. For example, in Na2SO4 there will be 2 Na atoms, 1 S atom and 4 O atoms. If the reaction was 2 Na2SO4, there would be 4 Na atoms, 2 S atoms and 8 O atoms.
In a chemical reaction what tells you how many atoms or molecules of a reactant or a product take part in a reaction?

subscript
Why is it necessary to identify the limiting reactant when you want to know how much product will form in a chemical reaction?
Identifying the limiting reactant allows you to determine which reactant will be completely consumed first, thereby limiting the amount of product that can be formed. This information is crucial for calculating the maximum amount of product that can be produced in a reaction, ensuring efficient use of reactants.
What is the reactant of 10.0 grams of total mass What is the chemical reaction?
It is possible to have ten grams of anything. Specifying the total weight tells you nothing about which reactant you have or what reaction it will undergo.
How can one Tell how much of a reactant will be used in a reaction?
The ratio of the coefficients tells the ratio of moles of reactants used in the reaction.
What tells you how many atoms or molecules of a reactant or a product take part in a reaction?
The coefficients in front of the reactants and products tell you how many atoms or molecules take part in a reaction. For example, the chemical equation 2 H2 plus O2 produces 2 H2O means that two hydrogen atoms react with one oxygen atom to produce two water molecules.
