Question

the complete redox reaction converting chemical energy to electrical energy in a Daniel cell is given by what​

Answer 1

Explanation:

galvanic cell is an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell. It generally consists of two different metals connected by a salt bridge, or individual half-cells separated by a porous membrane. Daniel cell is a galvanic cell.

Daniel cell has Zn as anode and Cu as cathode. The reactions of Daniel cell are,

At anode(Oxidation),

Zn(s)→Zn

2+

(aq)+2e

−

At cathode(Reduction),

Cu

2+

(aq)+2e

−

→Cu(s)

Hence overall reaction is,

Zn(s)+Cu

2+

(aq)→Zn

2+

(aq)+Cu(s)

Here the chemical energy is liberated when the redox reaction takes place in the cell and it is converted into electrical energy.
