Answer:the volume will be 2.15L
Explanation:
V1 = 2.35L
V2 =?
T1 = 20°C = 20 +273 = 293k
T2 = - 5°C = - 5 + 273 = 268k
V1 /T1 = V2 /T2
2.35 /293 = V2 /268
V2 = (2.35 / 293) x 268
V2 = 2.15L
Equation is as follow,
<span> SnCl</span>₂ <span> + PbCl</span>₄<span> </span>→ <span>SnCl</span>₄ <span> + PbCl</span>₂
Oxidation State of Sn on left hand side in SnCl₂ is +2, while that in SnCl₄ on right hand side is +4. Means Sn has lost two electrons. Hence, it is oxidized and has worked as a reducing agent (has reduced Pb from Pb⁺⁴ to Pb⁺²).
Oxidation State of Pb on left hand side in PbCl₄ is +4, while that in PbCl₂ on right hand side is +2. Means Pb has gained two electrons. Hence, it is reduced and has worked as an oxidizing agent (has oxidized Sn from Sn⁺² to Sn⁺⁴).
