Q.

Here is some information about the four countries. Based on this information, how would you classify each of these countries. Write ‘democratic’, ‘undemocratic’ or ‘not sure’ against each of these. a) Country A: People who do not accept the country’s official religion do not have a right to vote. b) Country B: The same party has been winning elections for the last twenty years. c) Country C: The Ruling party has lost in the last three elections. d) Country D: There is no independent election commission.

Q.

Which of the following statements are true about an electrolytic cell?

1. The reaction is non-spontaneous

2. A potential equal to the cell potential needs to be applied.

3. The flow of electrons is from anode to cathode.

4. The flow of current is from anode to cathode.

Q.

We know that an electrolytic cell has three main components, an electrolyte and two electrodes (an anode and a cathode) and the electrolyte can come in two forms, either as molten or in an aqueous solution. Which of the following statements accurately describes an electrolytic cell?

1. For aqueous solutions of the electrolyte, a gas may be produced at the anode.
2. Polyatomic ions, which are the anions of the electrolyte, are typically more easily oxidized than water.
3. In both molten or aqueous forms, the cation will be reduced and the anion will be oxidized.
4. Alkali or alkaline earth metals, which are the cations of the electrolyte, do not get oxidized in an aqueous solution since water is more easily oxidized.

Q.

Liquid water decomposes into gaseous hydrogen and gaseous oxygen. The best description of this reaction is:

1. an electrolytic cell; endothermic reaction

2. an electrolytic cell; exothermic reaction

3. a galvanic cell; exothermic reaction

4. a galvanic cell; endothermic reaction
