Answer: The final volume of this solution is 0.204 L.
Explanation:
Given: Molarity of solution = 2.2 M
Moles of solute = 0.45 mol
Molarity is the number of moles of solute present divided by volume in liters.
![Molarity = \frac{no. of moles}{Volume (in L)}](https://tex.z-dn.net/?f=Molarity%20%3D%20%5Cfrac%7Bno.%20of%20moles%7D%7BVolume%20%28in%20L%29%7D)
Substitute the values into above formula as follows.
![Molarity = \frac{no. of moles}{Volume (in L)}\\2.2 M = \frac{0.45}{Volume}\\Volume = 0.204 L](https://tex.z-dn.net/?f=Molarity%20%3D%20%5Cfrac%7Bno.%20of%20moles%7D%7BVolume%20%28in%20L%29%7D%5C%5C2.2%20M%20%3D%20%5Cfrac%7B0.45%7D%7BVolume%7D%5C%5CVolume%20%3D%200.204%20L)
Thus, we can conclude that the final volume of this solution is 0.204 L.
The question is incomplete, complete question is:
Study this chemical reaction:
![FeSO_4 (aq) + Zn (s)\rightarrow Fe (s) + ZnSO_4 (aq)](https://tex.z-dn.net/?f=FeSO_4%20%28aq%29%20%2B%20Zn%20%28s%29%5Crightarrow%20Fe%20%28s%29%20%2B%20ZnSO_4%20%28aq%29)
Then, write balanced half-reactions describing the oxidation and reduction that happen in this reaction.
Oxidation:
Reduction:
Answer:
Oxidation taking place in given reaction :
![Zn(s)\rightarrow Zn^{2+}+2e^-](https://tex.z-dn.net/?f=Zn%28s%29%5Crightarrow%20Zn%5E%7B2%2B%7D%2B2e%5E-)
Reduction taking place in given reaction;
Explanation:
Redox reaction is defined as the reaction in which oxidation and reduction reaction occur side by side.
Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.
Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
![X^{n+}+ne^-\rightarrow X](https://tex.z-dn.net/?f=X%5E%7Bn%2B%7D%2Bne%5E-%5Crightarrow%20X)
![FeSO_4 (aq) + Zn (s) \rightarrow Fe (s) + ZnSO_4 (aq)](https://tex.z-dn.net/?f=FeSO_4%20%28aq%29%20%2B%20Zn%20%28s%29%20%5Crightarrow%20Fe%20%28s%29%20%2B%20ZnSO_4%20%28aq%29)
In the given reaction, iron(II) ions are getting reduced and zinc metal is getting oxidized to zinc(II) ions.
Oxidation :
![Zn(s)\rightarrow Zn^{2+}+2e^-](https://tex.z-dn.net/?f=Zn%28s%29%5Crightarrow%20Zn%5E%7B2%2B%7D%2B2e%5E-)
