Which best describes the oxidizing agent in this reaction? Cl2(aq) + 2Br(aq) 2Cl(aq) + Br2(aq) Bromine (Br) is the oxidizing age
steposvetlana [31]
Answer:
            <span>Chlorine (Cl) is the oxidizing agent because it gains an electron.

Explanation:
                   Reaction is as follow,

</span><span>                     Cl</span>₂<span> (aq)  +  2 Br</span>⁻<span> (aq)    </span>→   <span> 2Cl(aq)  +  Br</span>₂ <span>(aq)

Oxidation Reaction:

                                    2 Br</span>⁻     →     Br₂  +  2 e⁻

Two atoms of Br⁻ (Bromide) looses two electrons to form Br₂ molecule. Hence it is oxidized and is acting as reducing agent.

Reduction Reaction:

                                   Cl₂  +  2 e⁻    →     2 Cl⁻

One molecule of Cl₂ gains two electrons to form two chloride ions (Cl⁻). Therefore, it is reduced and has oxidized Br⁻, Hence, acting as a oxidizing agent.

What os the formula for hexaboron tetrabromide
LekaFEV [45]

Answer:

B6Br4

Explanation:

Chemical formula gives a representation of the number of atoms that each element in a compound or molecule. In this question which is asking to give the formula of hexaboron tetrabromide, the hexa means 6 while the tetra means four.

Since the number of atoms of each element is written as a prefix before the main element, this means that the chemical formula of hexaboron tetrabromide will be B6Br4.
