Terms in this set (13)

  • Chemical Equation
    A symbolic representation showing reactants and products with their respective quantities in a chemical reaction.
  • Coefficient
    A number placed before a molecule or atom in an equation, indicating how many units are involved in the reaction.
  • Atom
    The smallest unit of an element, whose type and quantity must be equal on both sides of a balanced equation.
  • Reactant
    A substance present on the left side of a chemical equation, participating in the reaction.
  • Product
    A substance formed and shown on the right side of a chemical equation after the reaction.
  • Arrow
    A symbol in a chemical equation separating reactants from products, indicating the direction of the reaction.
  • Balanced Equation
    A state where both the type and number of atoms are identical on each side of the chemical equation.
  • Distribution
    The process of applying a coefficient to all atoms in a molecule, adjusting their total count in the equation.
  • Hydrogen
    An element commonly used in balancing examples, whose atom count must be equal on both sides of the equation.
  • Oxygen
    A diatomic element often involved in balancing, requiring careful adjustment of its atom count in equations.
  • Molecule
    A group of atoms bonded together, whose quantity is modified by coefficients in chemical equations.
  • Quantity
    The total number of atoms or molecules present, determined by multiplying subscripts by coefficients.
  • Subscript
    A small number written after an element symbol, indicating how many atoms of that element are in a molecule.
