Answer:

E^{0} for Zn^{2+}\mid Zn system would be -1.53 V

Explanation:

Determination of standard reduction potential of any system is done by placing the system in cathode and a reference half cell in anode and then evaluate the cell potential. The cell potential is the standard reduction potential of the system.

So E_{cell}^{0}=E_{system}^{0}-E_{reference}^{0}

As E_{H^{+}\mid H_{2}}^{0} is equal to 0 therefore cell potential is equal to reduction potential of any system by taking hydrogen electrode as a reference.

E_{Zn^{2+}\mid Zn}^{0} equal to -0.76 V with respect to hydrogen

E_{Fe^{3+}\mid Fe^{2+}}^{0} equal to 0.77 V with respect to hydrogen

Therefore standard reduction potential of Zn^{2+}\mid Zn system when Fe^{3+}\mid Fe^{2+} system is taken as reference is-

E_{cell}^{0}=E_{Zn^{2+}\mid Zn}^{0}-E_{Fe^{3+}\mid Fe^{2+}}^{0}

                          = -0.76 V - 0.77 V

                          = -1.53 V

Makovka662 [10]
The rate of dissolution of a solid solute into the solution decreases when you stop stirring it. Generally, stirring increases the dissolution rate of a solid into a solution. An example is coffee with sugar, the sugar dissolves faster when stirred versus when left to dissolve on its own.

Which phrase best describes the bond in H2?
Gala2k [10]

Answer and Explanation:

Two hydrogen atoms, each containing one electron, approach each other in the formation of a molecule of hydrogen. Each atom needs a total of two electrons to fill their outermost energy level and make them stable. The best choice is to share their single electrons. Hence, a pair of bonding electrons is shared between the hydrogen atoms in the molecules.

This constitutes a single covalent bond. Hence, the correct option is B)
