Does anyone know what metal this is? (right click -> "Open image in new tab" for larger image)
It has to be one of the following: magnesium, aluminum, zinc, tin, antimony, lead.
This metal was found in a laboratory where the students were performing a calorimetry experiment to determine specific heats of a few metals. I don't think it is lead (because of the color and that it is too toxic for students to use) and I don't think it is antimony (because that may be too expensive, but I could be wrong).
