Occurs at a specific temperature
The correct answer is option 4. The conversion of energy is from chemical to electrical energy. Voltaic cells are driven by a spontaneous reaction that produces an electric current. Voltaic cells are a type of electrochemical cell.
Aluminum has a chemical formula of Al, while diatomic bromine has a chemical formula of Br₂. The balanced chemical reaction is shown below:
<em>2 Al (s) + 3 Br₂ (l) → 2 AlBr₃ (s)</em>
The solid product is called Dibromoaluminum. The stoichiometric coefficients are used to balance the reaction to obey the Law of Conservation of Mass.
Answer:
Following are the solution to the given question:
Explanation:
In the aqueous solution of
ion is used to represent a
.
It is used to form a complex with iodide ions as
.
Conversion reaction:
![[Hg(H_2O)_4]^{2+} +4I^{-} \to [HgI_4]^{2-}+4H_20](https://tex.z-dn.net/?f=%5BHg%28H_2O%29_4%5D%5E%7B2%2B%7D%20%2B4I%5E%7B-%7D%20%5Cto%20%5BHgI_4%5D%5E%7B2-%7D%2B4H_20)
Following are the formation constants:
![k_f=\frac{[HgI_4]^{2-}}{[Hg(H_2O)_4]^{2+} [I^{-}]^4}](https://tex.z-dn.net/?f=k_f%3D%5Cfrac%7B%5BHgI_4%5D%5E%7B2-%7D%7D%7B%5BHg%28H_2O%29_4%5D%5E%7B2%2B%7D%20%5BI%5E%7B-%7D%5D%5E4%7D)
Following are the first step to the conversion:
![[Hg(H_2O)_4]^{2+} +I^{-} \to [HgI(H_2O)_3]^{+}+H_20](https://tex.z-dn.net/?f=%5BHg%28H_2O%29_4%5D%5E%7B2%2B%7D%20%2BI%5E%7B-%7D%20%5Cto%20%5BHgI%28H_2O%29_3%5D%5E%7B%2B%7D%2BH_20)
The answer is the second one I believe the light blue
