SUMMARY
The discussion centers on the rules governing the representation of chemical equations, specifically regarding coefficients and subscripts in the decomposition of substances. The example provided, 2H2O → 2H2 + O2, illustrates the correct representation, emphasizing that oxygen exists as a diatomic molecule (O2) rather than as individual atoms (O). The distinction is crucial for adhering to chemical laws, such as Lavoisier's law, which states that matter cannot be created or destroyed in a chemical reaction.
