In a chemical reaction, the number "2" typically indicates the stoichiometric coefficient, which represents the number of moles of a substance involved in the reaction. For example, in the reaction 2H₂ + O₂ → 2H₂O, the "2" before H₂ and H₂O signifies that two moles of hydrogen react with one mole of oxygen to produce two moles of water. This helps ensure that the law of conservation of mass is maintained, as the number of atoms of each element is balanced on both sides of the equation.
