Final answer:
To balance a chemical equation, you must ensure the number of atoms of each element is the same on both sides. In this case, the balanced chemical equation for the decomposition of calcium hydroxide is option b: 2Ca(OH)₂ → 2CaO + 2H₂O.
Step-by-step explanation:
The subject of the question is the balancing of chemical equations, which is a fundamental concept in chemistry. This involves ensuring that the number of atoms of each element is the same on both the reactant and product sides of the equation, in accordance with the Law of Conservation of Mass.
Let's examine each option:
In summary, the balanced chemical equation for the decomposition of calcium hydroxide to calcium oxide and water is represented by option b: 2Ca(OH)₂ → 2CaO + 2H₂O.
