Study Notes
Balanced Chemical Equation
- A balanced chemical equation obeys the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction.
- The balanced chemical equation for the reaction of hydrogen with oxygen to form water is 2H2 + O2 → 2H2O.
Balancing Chemical Equations
- The simplest method for balancing simple equations with a small number of atoms is by trial and error.
- A balanced chemical equation represents the exact quantities of reactants and products in a chemical reaction.
- The purpose of adjusting coefficients in a chemical equation is to ensure that the number of atoms of each element is the same on both the reactant and product sides.
