Question & Answer
-
What is the oxidation number of Cr in CrO3?
+6. Every oxygen, .”O”, molecule has a -2 charge, or “oxidation state”. Since the compound has 3 oxygen atoms and has a neautral charge, you can very easily solve for the Cr oxidation state algebraically: AX+BY=Z Where; X=Ion which you are trying to find oxidation state of. A is a coefficient t...more+

When chromium oxide is heated with aluminum powder, chlorine and aluminum oxide are formed. Which is more active, chlorine or aluminum?
You wrote “chlorine" but it must be “ chromium" 2Al + Cr2O3 –––> Al2O3 + 2Cr If the X metal becomes + from its neutral state and causes the + charged Y metal to become neutral, then X is more active than Y. It is understood from this reaction that Al is more active than Cr. more+

Why does iron oxide form hydrous iron oxide while chromium oxide does not?
Both Cr2O3 and Fe2O3 share a similar structure, and both can form some sort of passivating layer, but only one of them hydrates, thus turning into rust and providing a pathway for more water and O2 to further oxidize the iron. I believe the same applies to aluminum and nickel as well. iron seems to...more+
