What info do the reduction potentials of two elements give about a redox reaction between those elements?
The reduction potentials of two elements indicate their tendency to gain or lose electrons during a redox reaction. A higher reduction potential signifies a greater likelihood of gaining electrons and being reduced, while a lower reduction potential indicates a greater tendency to lose electrons and be oxidized. By comparing the reduction potentials, one can predict the direction of the electron flow in the reaction, determining which element will act as the oxidizing agent and which will act as the reducing agent. This information helps in assessing the feasibility and spontaneity of the redox reaction.

What will from a spontaneous redox reaction between two elements?
A spontaneous redox reaction between two elements occurs when one element is oxidized (loses electrons) and another is reduced (gains electrons) without the need for external energy. This typically happens when the two elements have a significant difference in their standard reduction potentials, leading to a favorable energy change. The result is the formation of new products, often in the form of ions or compounds, along with the release of energy, such as heat or light. For example, the reaction between zinc and copper sulfate results in the spontaneous displacement of copper by zinc, producing zinc sulfate and copper metal.
Is H2 plus Br2 equals 2HBr an oxidation-reduction reaction?
Yes, the reaction H2 + Br2 -> 2HBr is an oxidation-reduction (redox) reaction. In this reaction, hydrogen is oxidized from 0 to +1 oxidation state, and bromine is reduced from 0 to -1 oxidation state, indicating transfer of electrons between elements.

What is the overall voltage for the non spontaneous redox reaction involving Mg and Cu and their irons?
The overall voltage for the non-spontaneous redox reaction between Mg and Cu can be calculated by finding the difference in standard reduction potentials between the two half-reactions. The standard reduction potentials for Mg and Cu are -2.37 V and 0.34 V, respectively. Therefore, the overall voltage would be (-2.37 V) - (0.34 V) = -2.71 V.
How can one determine the cell potential in a chemical reaction?
The cell potential in a chemical reaction can be determined by calculating the difference in standard electrode potentials of the two half-reactions involved in the cell. The cell potential is the difference between the reduction potentials of the two half-reactions. The formula for calculating cell potential is Ecell Ered(cathode) - Ered(anode).
