<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Oxidizing agent is the agent which oxidizes the other substance and itself gets reduced. It undergoes reduction reaction in which, it gains electrons and also the oxidation state of the substance gets reduced.
Reducing agent is the agent which reduces the other substance and itself gets oxidized. It undergoes oxidation reaction in which, it looses electrons and the oxidation state of the substance is increased.
For the given chemical equation:
Half reactions for the given chemical reaction:
Copper is loosing 2 electrons, thus it is undergoing oxidation reaction and is considered as a reducing agent.
Silver ion is gaining 1 electron per atom, thus it is undergoing reduction reaction and is considered as an oxidizing agent.
Hence, is considered as an oxidizing agent and therefore the correct answer is Option B.
Metals that do not react with acid would be copper, platinum and mercury
According to the <span> chart represented above, I have determined the pair of atoms which has the greatest polarit and I am pretty sure that it is the first option from the scale :</span>A. Al-Si. I consider this to be correct due to their incredible difference <span>difference in electronegativity.
Hope it helps!</span>
I don't understand what is (g).
Maybe the answer is 2H<span>(aq)S</span>₂<span>−2(aq) </span>⇒ <span>H</span>₂<span>S</span>₂.
<u>Answer:</u> The concentration of solution will be 0.094 M.
<u>Explanation:</u>
To calculate the concentration of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is
We are given:
Conversion factor: 1L = 1000 mL
Putting values in above equation, we get:
Hence, the concentration of solution will be 0.094 M.
