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.
Answer:
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.
Answer:
it is an exothermic reaction
