What tells you how many atoms of a reactant or a product take part in a reaction?

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.

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 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.
What information in a balanced chemical equation shows how many moles of REACTANT ARE INVOLVED IN The reaction?

A number in front of a chemical formula in an equation that indicates how many molecules or atoms of each reactant and product are involved in a reaction?
This number tells a surprising amount about the chemical reaction. For starters, they are placed there so that there is an equal number of each element on either side of the equation. They also tell you the number of moles of each substance used in the reaction. The amount of a substance that contains as many atoms, molecules, ions, or other elementary units as the number of atoms in 0.012 kilogram of carbon 12. The number is 6.0225 × 1023, or Avogadro's number. Also called gram molecule). Ideally, you would want to use that many moles of each substance to get a complete reaction. This is not often practical, so it is used as a ratio, which is also helpful in determining the limiting reactant and other numerical values. Unfortunately, I'm not a very good teacher and there is a lot more to it than there first appears, but I hope this is at least a satisfactory explanation.In a chemical equation, numbers often appear in front of a chemical formula. These numbers tell you the number of molecules or atoms of each substance in the reaction.
In a chemical reaction what tells you how many atoms or molecules of a reactant or a product take part in a reaction?
A subscript
In achemical equation what tells you how many atoms or molecules of a reactant or a product take part in a reactin?
A subscript?
The number in front of a chemical formula that tells how many molecules or atoms of each reactant take part in a reaction called?
subscript
Why is it necessary to identify the limiting reactant when you want to know how much product will form in a chemical reaction?
The limiting reactant tells you how much of each reactant is formed. If you use the excess material a false answer for the calculated products will come out.
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.
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 does a chemical equation tell you that your observations do not?
A chemical equation tells you the reactants and the products, and also the ratios of each. The ratios can refer to numbers of atoms and molecules or numbers of moles of each reactant and product.
What information in a balance chemical equation shows how many moles of a reactant are involved in the reaction?
The coefficient (the number in front of the reactant) tells you the number of moles involved.

What tells the story of a chemical reaction?
The written statement that shows a chemical reaction is called an "equation". The representation of each reactant is called its chemical formula.
