A Stoichiometry Calculator is a powerful tool used in chemistry to perform calculations related to chemical reactions and the relationships between reactants and products. It helps chemists and students analyze and predict the outcomes of chemical reactions, including the quantity of substances involved, the molar ratios, and other important parameters. Here’s an overview of its functions and applications:

1. Balancing Chemical Equations: One of the fundamental uses of a Stoichiometry Calculator is to balance chemical equations. It ensures that the number of atoms of each element on both sides of the equation is equal, obeying the law of conservation of mass.

2. Molar Ratios: The calculator calculates molar ratios between reactants and products in a chemical reaction. This is essential for understanding how reactants are consumed and products are formed in a reaction.

3. Limiting Reactant: It identifies the limiting reactant in a chemical reaction, which is the reactant that is completely consumed and determines the maximum amount of product that can be formed.

4. Excess Reactant: Conversely, the calculator also determines the excess reactant, which is the reactant that is not completely consumed and remains after the reaction.

5. Reaction Yield: It calculates the theoretical yield of a product in a chemical reaction, which is the maximum amount of product that can be obtained under ideal conditions.

6. Mass-to-Mole Conversions: The calculator converts between mass and moles for reactants and products, allowing chemists to work with different units when conducting experiments.

7. Stoichiometric Calculations: It performs stoichiometric calculations to determine the amount of one substance needed to react with another substance completely or to produce a specific amount of a product.

8. Reaction Stoichiometry: Stoichiometry calculators help users understand the stoichiometry of a chemical reaction, which involves the quantitative relationship between the amounts of reactants and products.

9. Empirical and Molecular Formulas: These calculators assist in calculating empirical and molecular formulas based on the composition of compounds.

10. Reaction Balancing in Complex Reactions: In addition to simple reactions, stoichiometry calculators are used for balancing complex chemical reactions involving multiple reactants and products.
