What chemical property is most commonly used to classify igneous rocks?
iren2701 [21]

<span>Actually Igneous rocks are classified either based on grain size or based on mineralogy. However grain size is clearly not a chemical property. So we can say that they are classified chemically based on mineralogy or the abundance of quartz or silica present.</span>

What description best describes both mirrors and lenses?
WITCHER [35]
Mirrors reflect light and lenses refract light.
Mirrors form images by reflecting all light that is incident on their surface, which allows us to see the reflections of objects in mirrors. Lenses, on the other hand, bend light and allow it to pass through them. The bending of light is used to form enlarged images, and for many other purposes as well.
