Based on the answer you received for question 23, determine whether the cell is spontaneous or non-spontaneous Pb2+(aq)  +  2e-  = Pb(s)       Ecell = -0.13 V Ca2+(aq)  +  2e-  = Ca(s)     Ecell= -2.87 V Choose (A) or (B)

During a redox reaction

Which of the following is most likely to act as a Lewis acid?

Consider the following half-cell reactions: Zn2+(aq)  +  2e-  ↔  Zn(s)  Ecell = -0.76 V Cu2+(aq)  +  2e-  ↔  Cu(s)  Ecell = +0.34 V Identify the species (element or ion) that is getting oxidized Hint: The half-cell with the highest positive potential gets reduced

An aqueous solution is made by mixing 15% NH3 with DI water. Identify the acidic component in the newly formed solution.

Identify the oxidizing species in the following reaction Ag+(aq)   +  Al(s)  →  3Ag(s)  +  Al3+(aq)

Consider the reaction shown below: Ag+(aq) + 2NH3(aq) →  Ag(NH3)2+(aq) Identify the correct answer
