2. I believe it would be two but then again this is an incomplete answer so it is not two. It's probably going to be 3. Or 1. Because I took this test before a while back and I'm almost a 100% sure it's 1 or 3. Hope this helps slightly!
An oxidation-reduction (redox<span>) </span>reaction<span> is a type of chemical </span>reaction<span> that involves a transfer of electrons between two species. An oxidation-reduction </span>reaction<span> is any chemical </span>reaction<span> in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.</span>
Explanation:
Fe²⁺ + 2e⁻ → Fe
In a reduction half, the oxidizing agent is getting reduced. Such ion is donating electrons.
In a reduction process:
- there is removal of oxygen from a specie
- addition of hydrogen to a specie
- gain of electron by an atom
- decrease in oxidation number of an atom
- decrease in number of electronegative atoms surrounding the element in changing from reactants to products.
