Option C. Does not produce energy in the sun. Because energy in the sun is produced by fusion; this is the combination of two atoms, and that is the opposite to what the model shows.
When the cell potential is positive then the electrochemical reaction is spontaneous. The Ecell is positive when Zn serves as cathode and Mg serves as anode hence the reaction is spontaneous.
An electrochemical cell is any type of cell in which energy is produced by a spontaneous chemical reaction. Redox reactions that occur in an electrochemical cell produce energy.
An electrochemical cell becomes spontaneous only when Ecell is positive. Ecell is positive when a metal that has a more negative electrode potential serves as the anode.
Since Mg has a more negative electrode potential that Zn, it follows that a cell in which Mg is the anode and Zn is the cathode will have a positive Ecell and the reaction will be spontaneous.

Answer:
e) The activation energy of the reverse reaction is greater than that of the forward reaction.
Explanation:
- Activation energy is the minimum amount of energy that is required by the reactants to start a reaction.
- An exothermic reaction is a reaction that releases heat energy to the surrounding while an endothermic reactions is a reaction that absorbs heat from the surrounding.
- <em><u>In reversible reactions, when the forward reaction is exothermic it means the reverse reaction will be endothermic, therefore the reverse reaction will have a higher activation energy than the forward reaction.</u></em> The activation energy of the reverse reaction will be the sum of the enthalpy and the activation energy of the forward reaction.

Answer:
The death of Jesus was a unique, one of a kind, once for all death that ransomed mankind from sin and satisfied the righteousness of God and made it possible for man to once again have a personal relationship with God. The simple definition of death is separation.
