How can a redox reaction be used as a source of electrical energy?

A redox reaction be used as a source of electrical energy only when two half-reactions are physically separated. <span>The electrons that are released at the anode flow through the wire, producing an electric current. Galvanic cells therefore transform chemical energy into electrical energy that can then be used to do work.</span>

Explanation:

Electrical energy is the energy produced due to flow of electrons.

Whereas a reaction in which oxidation and reduction reaction takes place is known as a redox reaction. Basically, there is exchange of electrons that take place in a redox reaction.

For example, H_{2} + F_{2} \rightarrow 2HF

Oxidation half reaction: H_{2} \rightarrow 2H^{+} + 2e^{-}

Reduction half reaction: F_{2} + 2e^{-} \rightarrow 2F^{-}

Hence, this flow of electrons acts as a source of electrical energy.

What happens to the particles in matter when hear energy is added to them
Ipatiy [6.2K]
There are two possible situations.
1) If a phase change is not occurring, then the heat added contributes to increased translational energy of the particles. What that means is the particles move/vibrate faster.
2) If a phase change is occurring, then the heat added contributes to the breaking of bonds or intermolecular forces (depending on the chemical nature of the matter you're dealing with).

What is the difference between an enthalpy driven reaction and entropy driven reaction?
Crazy boy [7]
<span>Enthalpy is regarding the amount of heat that is given off or taken in during the process of a reaction, while entropy is about the disorderliness of a reaction. 
Both are related in the equation ∆G=∆H-T∆S, where ∆G is the Gibbs free energy. So we can say that a reaction is both enthalpy and entropy driven. It's like, both of them are interlinked with each other. </span>

Describe how two atoms come together to form a single covalent bond.​
KATRIN_1 [288]

When an atom donates electrons and other gains electrons, they form ions and the bond is called the ionic bond. When the atoms share electrons between them, they form a molecule, and the bond is called the covalent bond.

The atoms can share one, two or three pairs of electrons in the same bond. If one pair is shared it's called a single bond or a covalent simple; if two pairs are shared it's called a double bond or a covalent double, and if three pairs are shared it's called a triple bond or a covalent triple.

If this helps, please mark me as brainly, if not thats ok. im just here to help you get good grades. :D
