chemical equation
Balanced reaction notation
A chemical equation is a symbolic representation of a chemical reaction, showing reactants on the left, products on the right, and an arrow indicating the transformation: 2H₂ + O₂ → 2H₂O.
Coefficients indicate the relative amounts of each substance needed to balance the equation—ensuring atoms are neither created nor destroyed.
