Stoichiometry

2. ratio: The ratio of the number of moles of one substance to the number of moles of another substance in a balanced chemical equation.
3. reactant: The reactant that is not completely consumed in a chemical reaction, remaining after the limiting reactant is used up.
7. mass: The mass of one mole of a substance, usually expressed in grams per mole (g/mol).
8. equation: A symbolic representation of a chemical reaction using chemical formulas and symbols.
10. Substances formed as a result of a chemical reaction.
13. A number written slightly below and to the right of an element's symbol in a chemical formula, indicating the number of atoms of that element in a molecule.
14. number: The number of atoms, molecules, or formula units in one mole of a substance, approximately

1. equation: An equation representing a chemical reaction with an equal number of atoms of each element on both sides.
2. A unit used to measure the amount of substance, equal to Avogadro's number of atoms, molecules, or formula units.
4. The quantitative relationship between reactants and products in a chemical reaction.
5. reaction: A process in which one or more substances are converted into different substances.
6. Substances that undergo a chemical change in a reaction.
9. reactant: The reactant that is completely consumed in a chemical reaction, limiting the amount of product that can be formed.
11. ratio: The ratio of the masses of one substance to the mass of another substance in a chemical reaction.
12. Numbers in a balanced chemical equation representing the relative amounts of reactants and products.
