I’m sorry, but the chemical equation you provided is incorrect. Cr2O3 is a green solid, existing as a protective layer on the surface of chromium metal. Fm, or fermium, is a very rare chemical element, belonging to the actinide group, with the symbol Fm and atomic number 100. However, there is no substance called CrFmO3.
Please check your chemical equation again. If you have any other chemistry-related questions, don’t hesitate to contact me.
