Why does the graphite rod act as a positive terminal where as the zinc casing a negative terminal?

The graphite rod acts as the positive terminal because it is the cathode where reduction reactions occur, while the zinc casing acts as the negative terminal because it is the anode where oxidation reactions occur. This is due to their differences in electrode potential and their roles in the electrochemical reaction process.


What does the reduction potential tell you about the stability of an element?

The reduction potential indicates how readily an element can gain electrons and be reduced; a higher (more positive) reduction potential signifies a greater tendency to accept electrons and thus indicates greater stability in its reduced form. Conversely, a lower (more negative) reduction potential suggests that the element is less stable when reduced and more likely to lose electrons. Therefore, elements with high reduction potentials are often more stable in their reduced states, while those with low potentials may be more reactive or prone to oxidation.

What is the definition for polarity?

Polarity refers to the positive or negative charge of a molecule or its parts. In chemistry, it describes the separation of charge in a molecule that has areas of differing electronegativity. A polar molecule has a positive end and a negative end.
