A gas occupies 4.30 Liters at STP. What volume does it occupy at 2.56 atm and 302
laiz [17]

Answer:

V₂ = 1.86 L

Explanation:

Given data:

Initial volume = 4.30 L

Initial pressure = 1 atm

Initial temperature = 273.15 K

Final temperature = 302 K

Final volume =  ?

Final pressure = 2.56 atm

Solution:

According to general gas equation:

P₁V₁/T₁ = P₂V₂/T₂

V₂ = P₁V₁T₂ /T₁ P₂

V₂ = 1 atm ×4.30 L × 302 K / 273.15 K × 2.56 atm

V₂ = 1298.6 atm.L.K / 699.26 K.atm

V₂ = 1.86 L

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.
