Which best describes the oxidizing agent in this reaction?
2 answers:
Answer: Chlorine (Cl) is the oxidizing agent because it gains an electron.
Explanation:
The redox reaction is:
On reactant side:
Oxidation state of chlorine = 0
Oxidation state of bromine = -1
On product side:
Oxidation state of chlorine = -1
Oxidation state of bromine = 0
The oxidation state of chlorine reduces from 0 to -1 it is getting reduced by gain of electrons and it undergoes reduction reaction. As chlorine gets reduced, it acts as oxidizing agent.
The oxidation state of bromine increases from -1 to 0. Thus, it is getting oxidized by loss of electrons and it undergoes oxidation reaction.As bromine gets oxidized, it acts as reducing agent.
Thus Chlorine (Cl) is the oxidizing agent because it gains an electron.

Answer: Option (a) is the correct answer.
Explanation:
Subscript present in chemical formula of a compound represents the number of atoms of the element actually present in it.
For example, in the subscripts present in it are 7, 7, 1, and 2.
A subscript is not responsible for determining the relative mass of each type of an atom because a subscript simply represents the number of atoms of each type of an element participating or combining with other atoms of a compound.
Thus, we can conclude that the statement subscripts represent the relative mass of each type of atom in the compound, is false.
