Brief Explanations

Los cambios químicos a menudo presentan ciertas evidencias. La formación de un precipitado (P) ocurre cuando dos soluciones se mezclan y se forma un sólido. Un cambio en la energía térmica (E) se ve reflejado en cambios de temperatura al combinar sustancias. El cambio de color (C C) es otra señal posible de un cambio químico, y la producción de un gas (G) se manifiesta a menudo con burbujas.
