Answer:

Cl⁻ is the reducing agent.

Explanation:

In any complete redox reaction there is one species which gets oxidized (by giving electrons) and another reduced (by accepting electrons)

During oxidation the chemical species undergoes an increase in oxidation number.

During reduction the chemical species undergoes a decrease in oxidation number.

The reagent which undergoes oxidation acts as reducing agent and the one which undergoes reduction acts as oxidizing agent.

So here in the given problem, MnO₂ undergoes reduction and Cl- undergoes oxidation hence Cl- is the reducing agent.

MnO2 (s) + 4H+(aq) + 2Cl- ---> Mn2+(aq) + 2H2O(l) + Cl2(g)

4H+ + 2e- + MnO2 —> Mn2+ +2H2O. Reduction

2Cl- —> Cl2 +2e- Oxidation

A reducing agent (also called a reductant or reducer) is an element or compound that loses (or "donates") electrons to another chemical species in a redox chemical reaction.

In this case the reducing agent is the Cl-

Answer is: sodium (Na) and iodine (I₂).

<span> First ionic bonds in this salt are separeted because of heat:
</span>NaI(l) → Na⁺(l) + I⁻(l).

Reaction of reduction at cathode(-): Na⁺(l) + e⁻ → Na(l) /×2.

2Na⁺(l) + 2e⁻ → 2Na(l).

Reaction of oxidation at anode(+): 2I⁻(l) → I₂(l) + 2e⁻.

The anode is positive and the cathode is negative.

A reaction occurs between the two gases Chlorine monofluoride (ClF) and Fluorine (F₂) when they are added together and as a result of the reaction a compound named, Chlorine trifluoride (ClF₃) is formed.

The reaction which occurs by addition of Chlorine monofluoride (ClF) and Fluorine (F₂) is as follows -

ClF (g) + F₂ (g) = ClF₃ (l)

When one molecule of Chlorine monofluoride (ClF) reacts with one molecule of Fluorine (F₂) gas, both the gases react together to form one molecule of Chlorine trifluoride (ClF₃) which is a liquid. Therefore, the above reaction is already balanced.

Chlorine trifluoride (ClF₃) is a greenish-yellow liquid which acts as an important fluorinating agent and is also an interhalogen compound (compounds that are formed by mixing two different halogen compounds together). Other than it's liquid state ClF₃ also can exist as a colorless gas. This compound ClF₃ is a very toxic, very corrosive and powerful oxidizer used as an igniter and propellent in rockets.
