Balancing Equations

Subject: Chemistry

Book: General Chemistry

Balancing chemical equations ensures that the number of atoms of each element is the same on both reactant and product sides, reflecting the law of conservation of mass. Coefficients are adjusted to balance atoms, but subscripts within chemical formulas must remain unchanged. For example, balancing hydrogen combustion: 2H2 + O2 → 2H2O. Properly balanced equations are essential for accurate stoichiometric calculations in chemistry.
