(a) Interpretation: Whether the cell is a galvanic cell or an electrolytic cell should be determined. Concept introduction: The electrolytic cell is an electrochemical cell which an electric current is used to drive a non-spontaneous reaction. So, electrolytic cell is the reverse of galvanic cell. Electrolytic cell converts electrical energy to chemical energy while galvanic cell converts chemical energy into electric energy. An electrolytic cell has two inert electrodes dipped in an electrolyte. These electrodes are connected to source of electric current.

Whether the cell is a galvanic cell or an electrolytic cell should be determined.
Concept introduction:
The electrolytic cell is an electrochemical cell which an electric current is used to drive a non-spontaneous reaction. So, electrolytic cell is the reverse of galvanic cell. Electrolytic cell converts electrical energy to chemical energy while galvanic cell converts chemical energy into electric energy. An electrolytic cell has two inert electrodes dipped in an electrolyte. These electrodes are connected to source of electric current.
Interpretation Introduction
(b)
Interpretation:
The anode and cathode should be labeled and the direction of ion flow should be shown.
Concept introduction:
In electrolysis, Anode is where oxidation occurs and indicated by positive sign. Cathode is where the reduction takes place and indicated by a negative sign.
Electrons flow from anode towards the cathode. Anode attracts anions and cathode attracts cations.
Interpretation Introduction
(c)
Interpretation:
The balanced equation for the anode, cathode and overall reaction should be written.
Concept introduction:
When an aqueous solution is electrolyzed, electrolysis products may differ than when the molten salt is electrolyzed. Because water is also electrolyzed.
In the solid state, oxalic acid occurs as
a dihydrate with the formula H2C2O4
C+2H2O. Use this formula to
calculate the formula weight of oxalic
acid. Use the calculated formula
weight and the number of moles
(0.00504mol)
of oxalic acid in each titrated
unknown sample recorded in Table
6.4 to calculate the number of grams
of pure oxalic acid dihydrate
contained in each titrated unknown
sample.

Consider a pair of elements with 2p and 4p valence orbitals (e.g., N and Se). Draw their
(2p and 4p AO's) radial probability plots, and sketch their angular profiles. Then, consider these
orbitals from the two atoms forming a homonuclear л-bond. Which element would have a
stronger bond, and why?
(4 points)
Write the reaction and show the mechanism of the reaction. Include the mechanism
for formation of the NO2+
2. Explain, using resonance structures, why the meta isomer is formed. Draw possible
resonance structures for ortho, meta and para.
