3rd law of thermodynamics..<br><br> 2 Different Examples((Thnks))
VLD [36.1K]

Answer:

See explanation

Explanation:

The third law of thermodynamics states that "the entropy of a perfect crystal of a pure substance approaches zero as the temperature approaches zero" (Wikipedia).

One example of the third law of thermodynamics has to do with steam. Steam is gaseous water. Since it is a gas, its molecules are free to move around therefore its entropy is high. When the temperature of the steam is decreased below 100 degrees, the molecules of steam loose energy and turn into liquid water and do not move as freely as they did in the gaseous state. If the temperature is further decreased to yield ice at zero degrees, the molecules of water are "frozen" in their positions and the entropy of the system decreases to zero.

Also, the ions in ionic crystal solids move around when the substance is in solution or in molten state hence the substance conducts electricity. When the ionic substance is in solid state, the ions do not move about and the entropy of the solid system tends towards zero.

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.
