A balanced chemical equation reflects the idea that the mass of the products is equal to the mass of the reactants. The correct option is C.
In a balanced chemical equation, the mass of the products must be equal to the mass of the reactants.
According to the law of conservation of mass, in a chemical reaction, the mass of the products must be equal to the mass of the reactants because matter cannot be created or destroyed, it only can be transformed.
For example, for the given reaction:
CH₄ + 2O₂ → CO₂ + 2H₂O
The mass of the reaction is:
[tex] m_{CH_{4}} + m_{O_{2}} = m_{CO_{2}} + m_{H_{2}O} [/tex]
So the sum of the masses of the reactants must be equal to the sum of the masses of the products.
Therefore, the correct option is C.
