  • Stoichiometry
    Numerical relationships between compounds in a balanced chemical equation, used to predict product or reactant amounts.
  • Balanced Chemical Equation
    A symbolic representation where the number of atoms for each element is equal on both sides, ensuring mass conservation.
  • Reactant
    A starting substance in a chemical reaction, present on the left side of a chemical equation.
  • Product
    A substance formed as a result of a chemical reaction, shown on the right side of a chemical equation.
  • Coefficient
    A number placed before a chemical formula in an equation, indicating the relative amount of each substance.
  • Mole
    A unit representing 6.022 x 10^23 particles, used to count atoms, molecules, or ions in chemistry.
  • Stoichiometric Chart
    A visual tool guiding the stepwise conversion from given information to unknown quantities in stoichiometric calculations.
  • Mole-to-Mole Comparison
    A step using coefficients from a balanced equation to relate the amounts of two substances in a reaction.
  • Given Information
    The known quantity or substance provided in a problem, serving as the starting point for calculations.
  • Unknown
    The quantity or substance to be determined in a stoichiometric problem, typically the calculation's goal.
  • Gram
    A metric unit of mass commonly used to express the amount of a substance in stoichiometric problems.
  • Atom
    The smallest unit of an element, which can be counted or converted in stoichiometric calculations.
  • Molecule
    A group of atoms bonded together, representing the smallest unit of a compound involved in reactions.
  • Formula Unit
    The simplest ratio of ions represented in an ionic compound, used in stoichiometric conversions.
  • Ion
    A charged particle, either positive or negative, that may be counted or converted in stoichiometric calculations.
