Question

assuming that the mineral in this video smells like rotten eggs, what mineral are you looking at?
magnetite
halite
graphite
sulfur
calcite

Explanation:

To determine the mineral, we analyze the properties: the mineral in the video has a yellow appearance and smells like rotten eggs (a characteristic of sulfur, as sulfur emits a rotten - egg - like smell when it undergoes certain reactions or is disturbed). Magnetite is magnetic and has a different appearance and smell. Halite is salt (sodium chloride) and has a salty taste and a different smell. Graphite is black and is used in pencils, with no rotten - egg smell. Calcite has different physical and chemical properties and no such smell. So the mineral is Sulfur.

Answer:

D. Sulfur (assuming the options are labeled A - E with D being Sulfur, if the original options had Sulfur as the last one or a specific label, adjust the label accordingly. But based on the given options, the correct one is Sulfur among the listed options: Magnetite, Halite, Graphite, Sulfur, Calcite. So the answer is the option with "Sulfur".)
