What gets oxidized in a galvanic cell made with magnesium and zinc electrodes?
ankoles [38]

Answer: Magnesium

Explanation:

Galvanic cell is a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy.

The standard reduction potential for magnesium and zinc are as follows:

E^0_{[Mg^{2+}/Mg]}= -2.37V

E^0_{[Zn^{2+}/Zn]}=-0.76V

Reduction takes place easily if the standard reduction potential is higher (positive) and oxidation takes place easily if the standard reduction potential is less (more negative).

Here Mg undergoes oxidation by loss of electrons, thus act as anode. Zinc undergoes reduction by gain of electrons and thus act as cathode.

Mg\rightarrow Mg^{2+}+2e^-

Zn^{2+}+2e^-\rightarrow Zn

Thus magnesium gets oxidized.

Draw the structure of (z)-3-bromo-6-methyl-2-heptene. be sure the stereochemistry is drawn clearly.
Anna007 [38]

Explanation: In IUPAC, E-Z convention is given for describing the cis - trans notation to the isomers. According to CIP rule, the groups on the doubly bonded carbon atoms are given priorities based on the the atomic masses of first connected atom.

If the highest priority groups are on the same side, it is known as Z-form and if the highest priority groups are on opposite side, it is known as E-form.

We are given (Z)-3-bromo-6-methyl-2-heptene, in this the highest priority groups are bromine on one side and methyl- group on another side.

The structure is provided in the image below.
