What statement is true for the following half cell reaction F2(g)  +   2e-  ↔  2F-(aq)  Ecell = + 2.87 V

Deathcare that minimizes the use of energy in service, and offers products that ban the use of toxic or hazardous materials is called

The burning chamber in a crematory is called a

What is the proper term used to describe the initial notification informing a funeral home that a death has occurred?

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 acting as the reducing agent Hint: The half-cell with the highest positive potential gets reduced

Two half-cell reactions are shown below: Fe2+(aq)  +  2e-   ↔  Fe(s)     Ecell = – 0.44 V Cu2+(aq)  +  2e-  ↔  Cu(s)    Ecell = +0.34 V Hint: The half-cell with the highest positive potential gets reduced. the other half-cell must get oxidized. Find the Gibbs free energy for the above cell reaction (ΔG = -nFE: F = 96485 C, n = no. of electrons and E = cell potential). Use the cell voltage you received in questions 21.

Consider the following half-cell reactions: Zn2+(aq)  +  2e-  ↔  Zn(s)  Ecell = -0.76 V Cu2+(aq)  +  2e-  ↔  Cu(s)  Ecell = +0.34 V If a cell is built by combining above two half-cells, what will be its cell potential?  Hint: The half-cell with the highest positive potential gets reduced: Ecell= E(cathode) – E(anode)

If Al3+(aq) = 0.36 M, Sn4+ (aq) = 0.086 M and Sn2+(aq) = 0.54 M, calculate the Ecell of this non standard cell Use: Al3+(aq)  +  3e-  ↔  Al(s)            Ecell = -1.676 V Sn4+(aq)  +  2e-  ↔  Sn2+(aq)  Ecell = 0.154 v

Based on the Gibbs free energy you received for question (25), calculate the equilibrium constant for the reaction. Use ΔG = -RT ln K: Temperature 25 Celsius, R = 8.314 J / mol. K
