A Rusty Moon and the Year of the Snake – Braille Refreshers 2025012001

The Moon Is Rusting, and Researchers Want to Know Why according to NASA! In short, hematite (a form of rust or "iron oxide") has been found on the moon, but that is weird because iron *oxide* requires a lot of oxygen to form, and ... the moon does not have a lot of oxygen.

Hematite's chemical formula is "Fe subscript 2 O subscript 3" (That is just two iron atoms and THREE Oxygen atoms). Here is the chemical formula using Unicode symbols: Fe₂O₃

Which option below gives the most preferred writing of the chemical formula for hematite in contracted UEB?

Why are we thinking about Earth's moon? It's because Lunar New Year is January 29, 2025, and that marks the beginning of the Year of the Snake!
