Barbara places an object in front of a mirror. The mirror produces an image that is inverted, real, and smaller than the object.
Which kind(s) of mirror could Barbara be using? convex, because concave and plane mirrors produce only virtual images concave, because plane and convex mirrors produce only upright virtual images concave or convex, because both types of mirrors produce images that are inverted and real convex or plane, because both types of mirrors produce an image that is smaller than the object
Plane mirrors, convex mirrors, and diverging lenses can never produce a real image. A concave mirror and a converging lens will only produce a real image if the object is located beyond the focal point therefore if the image Barbara is looking at is inverted, real, and smaller than the object then obviously she is using a concave mirror
An element with a valence of 8 are most likely noble gases (He, Ne, Ar, etc) which means they're already stable so they dont need to undergo chemical bonds with another atom because they already have a full valence shell.
Sample Response: "No, steel and carbon would not form metallic bonds because metallic bonds only form between metals. Iron is a metal, but carbon is not."
