  • Limiting Reagent
    Reactant fully used up in a reaction, setting the maximum possible amount of product formed.
  • Excess Reagent
    Reactant remaining after a reaction finishes, present in greater quantity than needed to react completely.
  • Theoretical Yield
    Maximum possible amount of product calculated from the limiting reagent, assuming perfect reaction efficiency.
  • Stoichiometry
    Quantitative relationship between reactants and products in a chemical equation, used for conversion calculations.
  • Balanced Chemical Equation
    Representation of a chemical reaction with equal numbers of each atom on both sides, ensuring mass conservation.
  • Coefficient
    Number placed before a chemical formula in an equation, indicating the relative amount of each substance involved.
  • Mole
    Unit representing 6.022 x 10^23 particles, used to count atoms, molecules, or formula units in chemical calculations.
  • Grams of Given
    Initial mass of a reactant provided for stoichiometric calculations in a chemical reaction.
  • Moles of Unknown
    Calculated amount of a product or reactant not initially given, found using stoichiometric relationships.
  • Product
    Substance formed as a result of a chemical reaction, determined by subtractions of limiting reagent.
  • Reactant
    Starting substance in a chemical reaction, which undergoes change to form products.
  • Formula Unit
    Smallest repeating unit of an ionic compound, used to express quantities in stoichiometric calculations.
  • Yield
    Amount of product obtained from a chemical reaction, often compared to the theoretical maximum.
