The answer is c.
There are 3 carbon atoms and six hydrogen atoms in a double-bond linear chain.
i.e.
H2C=CH-CH3
Answer:
Option (A) Each Zn atom loses 2 electrons, and each Co2+ ion gains 2
Explanation:
To know the right answer to the question, let us observe the changes in the oxidation number of Zn and Co. This is illustrated below:
Zn(s) + Co2+(aq) → Zn2+(aq) + Co(s)
The oxidation number of Zn changes from 0 to +2 indicating that Zn has lose 2 electrons.
The oxidation number of Co changes from +2 to 0 indicating that Co has gain 2 electrons.
Therefore, option A is the correct answer.
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).
