which statement best describes chemical properties of matter?\no chemical properties, such as density, must be observed when a substance is in its natural state at room temperature and normal atmospheric pressure.\no chemical properties, such as reactivity, must be observed when a substance is in its natural state at room temperature and normal atmospheric pressure.\no chemical properties, such as combustibility, are generally observed as the identity of a substance changes and one or more new substances form.\no chemical properties, such as boiling point, are generally observed as the identity of a substance changes and one or more new substances form.

Answer

Brief Explanations:

Las propiedades químicas se definen como las características de una sustancia que se manifiestan durante o después de una reacción química, donde la identidad de la sustancia cambia y se forman uno o más nuevos productos. La densidad y el punto de ebullición son propiedades físicas, no químicas. La reactividad y la combustibilidad son propiedades químicas y se observan cuando la sustancia experimenta un cambio de identidad.

Answer:

Chemical properties, such as combustibility, are generally observed as the identity of a substance changes and one or more new substances form.
