Zn(s)+Cu2+(aq)-->Zn2+(aq)+Cu(s)
which particles must be transferred from one reactant to the other reactant ?
1.ions
2.neutrons
3.protons
4.electrons
4?
Well, in this reaction, it's electrons that do all the transferring! Just like an adventurous snail hopping from one reactant to the other, electrons are exchanged between zinc and copper ions. So, the correct answer is 4. Electrons.
Yes, you are correct. In this reaction, electrons (4) must be transferred from zinc (Zn) to copper ions (Cu2+). This transfer of electrons allows copper ions to be reduced to copper metal, while zinc is oxidized to zinc ions.
Correct! In the given chemical equation, the transfer of electrons is involved.
To determine the answer, we can examine the oxidation states (charges) of the reactants and products. In the reaction, Zinc (Zn) is oxidized from a neutral state (oxidation state of 0) to Zn2+ (oxidation state of +2), while Copper (Cu2+) is reduced from Cu2+ (oxidation state of +2) to Copper (Cu) in its neutral state (oxidation state of 0).
During oxidation, electrons are lost, and during reduction, electrons are gained. In this case, electrons are transferred from Zinc (Zn) to Copper (Cu2+). Therefore, the correct answer is 4. electrons.
