Should be an igneous rock.
Answer:
Iron is being oxidized at the anode and water is acting as the electrolyte.
Explanation:
When iron is exposed to oxygen and water , the rusting of iron takes place.
<u>The reaction taking place at anode : Oxidation of iron.</u>

The reaction taking place at cathode : Reduction of oxygen in the air.
The overall reaction:

The rust that is hydrated iron(III) oxide can form iron(II) ions which can react further with oxygen.

Thus, from the above reactions ,
Iron is being oxidized at the anode and water is acting as the electrolyte.
Answer:
Explanation:
Covalent catalysis is when a transient covalent bond is formed between substrate and residues such that so the enzyme nucleophilic group on an electrophilic moiety of the substrate is bound at the active site. Metal ion catalysis involves activating bound water through forming nucleophilic hydroxide ion.
