Cr reacts with O2
In a full sentence, you can also say Cr (chromium) reacts with O2 (oxygen) and produce CrO ()
This equation does not have any specific information about phenomenon.
In this case, you just need to observe to see if product substance CrO, appearing at the end of the reaction.
Or if any of the following reactant substances O2 (oxygen), disappearing
We no further information about this chemical reactions.
Cr + 3HCl + HNO3 → 2H2O + NO + CrCl3 2Cr + 3S → Cr2S3 Cr + 2HCl → H2 + CrCl2 View all equations with Cr as reactant
