Answer:
1) Redox reaction.
2) NaCl + l₂
3)2NaI + Cl₂ → 2NaCl + l₂
Explanation:
Chemical equation:
NaI + Cl₂ → NaCl + l₂
Balanced chemical equation:
2NaI + Cl₂ → 2NaCl + l₂
The type of reaction is oxidation reduction reaction.
The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
Consider the above given reaction:
2NaI⁻¹ + Cl⁰₂ → 2NaCl⁻¹ + l⁰₂
Iodine is oxidized while chlorine is reduced.
Product is:
Sodium chloride and iodine gas is produced.
