Answer 2

1. :is a redox reaction. Explanation: Redox reactions are the chemical reactions where oxidation as well as reduction takes place. In the reaction, iron or Fe is getting oxidised and sulphur or S is getting reduced.
2. Aluminum Sulfate is ionic. It's made up of the aluminum ion, , and the polyatomic ion sulfate, . Rather than existing as discrete molecules it exists as a crystal lattice of aluminum and sulfate ions in the ratio 2:3, held together by electrostatic charges between positive and negative ions.
3. is CuSo4 +H2S =CuS +H2So4 a double displacement reaction ? ... Yes the reaction is a double displacement reaction. 2. This is because Cu2+ displaces S2- (sulphide ions) from hydrogen sulphide, and H+ displace SO.
