Solution

Cuando balanceamos ecuaciones químicas, solo podemos cambiar los coeficientes y no los subíndices porque los coeficientes indican la cantidad de moléculas o moles de una sustancia, mientras que los subíndices indican el número de átomos de cada elemento en una molécula. Cambiar los subíndices alteraría la identidad química de las sustancias involucradas, creando compuestos diferentes. Por ejemplo, cambiar el subíndice en H₂O a H₂O₂ cambiaría el agua a peróxido de hidrógeno, que es una sustancia completamente diferente. En cambio, ajustar los coeficientes permite balancear la ecuación sin modificar la naturaleza de las sustancias, asegurando que se cumpla la ley de conservación de la masa.
