Chemical Equations
1. Word Equation:
A word equation represents the names of the reactants and products.
Example:
Magnesium + Oxygen → Magnesium Oxide
2. Balanced Chemical Equation:
A balanced chemical equation follows the Law of Conservation of Mass, meaning the number of atoms of each element is the same on both sides of the equation.
Example:
2Mg + O2 → 2MgO2
This shows that 2 atoms of magnesium react with 1 molecule of oxygen to form 2 units of magnesium oxide.
