2) ¿Cuál de los siguientes hechos no es una evidencia de una reacción química? a) Presencia de un catalizador b) Cambio de color
Pepsi [2]

Answer:

a) Presencia de un catalizador

Explanation:

Los dos tipos de cambios que experimentan las sustancias en la química son cambios químicos y físicos.

Un cambio físico es un cambio es un cambio en el que la sustancia cambia en su apariencia o su forma de una manera que es reversible y en la que no se forma una nueva sustancia.

Un cambio químico es aquel en el que hay un cambio en las sustancias presentes y se forma una nueva sustancia.

La evidencia de que ha tenido lugar un cambio químico incluye

1) La formación de un precipitado a partir de la mezcla de sustancias.

2) Un cambio en el color de las sustancias.

3) Un cambio en el olfato (que desprende un olor) o en el sabor.

4) La sustancia produce luz (brilla)

5) El volumen total cambia

6) Cambio de temperatura (la mezcla se calienta o enfría)

Por lo tanto, la presencia de un catalizador, que es una sustancia que no participa en una reacción pero aumenta la velocidad de reacción, no es evidencia de una reacción química.
