a. Describe the direction of electron flow between the electrodes when switch S is closed.b. Write the balanced half-reaction equation that will occur in half-cell 1 when switch S is closed.c. In which half-cell will oxidation occur when switch S is closed?

a Describe the direction of electron flow between the electrodes when switch S is closedb Write the balanced halfreaction equation that will occur in halfcell 1 class=

Respuesta :

answer and explanation

a. the direction of electron flow when switch S is closed is from the Zn to Pb.

the Zn electrode will lose mass while the Pb electrode will gain mass

b. in half cell 1 the following reaction will occur:

Pb²⁺(aq) + 2e -> Pb(s)

c. oxidation occurs on the Zn half cell according to the equation

Zn(s) => Zn²⁺ (aq) + 2e
