During an electrochemical reaction, electrons move through the external circuit toward the and positive ions in the cell move toward the . a. cathode, anode b. anode, anode c. cathode, cathode d. anode, cathode

cathode , anode

Explanation:

Electrochemical cell or Galvanic cell is a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy.

Oxidation is loss of electrons and reduction is gain of electrons. Reduction takes place at cathode and oxidation takes place at anode.

The lost electrons at anode move towards the cathode through external circuit and thus the positive ions remain in anodic solution.

To neutralise the positive charge in the anodic compartment, the oppositely charged ions from salt bridge move towards the anode.

for points guys

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
