Molecular weight calculation: 51.9961*2 + 15.9994*3 ›› Percent composition by element Question: Is Cr2O3 an ionic or Molecular bond ? Answer: Cr2O3 ( Chromium(III) oxide ) is an ionic bond What is chemical bond, ionic bond, Molecular bond? Chemical bond A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. In this video we'll balance the equation Cr + O2 = Cr2O3 and provide the correct coefficients for each compound.To balance Cr + O2 = Cr2O3 you'll need to be Predicted data is generated using the US Environmental Protection Agency’s EPISuite™. Log Octanol-Water Partition Coef (SRC): Log Kow (KOWWIN v1.67 estimate) = 2.97 Boiling Pt, Melting Pt, Vapor Pressure Estimations (MPBPWIN v1.42): Boiling Pt (deg C): 576.48 (Adapted Stein & Brown method) Melting Pt (deg C): 248.32 (Mean or Weighted MP) VP(mm Hg,25 deg C): 4.35E-012 (Modified Grain method Answer: Cr2O3 (Chromium (III) oxide) is an ionic bond What is chemical bond, ionic bond, Molecular bond? Cr2O3 is usually considered to be an ionic compound, in which instance its proper name is "chromium (III) oxide" (now preferred) or "chromic oxide" (more often used about 50 years ago.) If Cr2O3 F.
