The spontaneous reaction that occurs when the cell in the picture operates is as follows: 2Ag+ + Cd(s) à 2 Ag(s) + Cd2+ (A) Voltage increases. (B) Voltage decreases but remains > zero. (C) Voltage becomes zero and remains at zero. (D) No change in voltage occurs. (E) Direction of voltage change cannot be predicted without additional information.

The question is incomplete, the remaining part of the question is

Which of the above occurs for each of the following circumstances?

A 50-milliliter sample of a 2-molar Cd(NO3)2 solution is added to the left beaker.

Voltage decreases but remains > zero.

Explanation:

Given the balanced redox reaction equation:

2Ag^+(aq) + Cd(s) > 2 Ag(s) + Cd^2+(aq)

Concentration affects the cell voltage according to Nernst equation. Change in concentration must lead to a change in cell Voltage.

As the concentration of the Cd(NO3)2 solution is increased, voltage decreases because of the increase in the concentration values but voltages remains above zero.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

im pretty sure its b
