Answer:
-0.044 V
Explanation:
The overall electrode potential is usually estimated by subtracting the potential of the reference electrode from the potential of the system in question. In the given problem, the standard electrode potential of silver-silver chloride with respect to the standard hydrogen electrode is +0.197 V. In addition, the potential of the calomel reference electrode with respect to the standard hydrogen electrode is +0.241 V. Using the data above, the potential of with respect to silver-silver chloride is equivalent to 0.197-0.241 = -0.044 V.
Answer:
Option B. Single replacement reaction
Explanation:
To know which option is correct, it is important that we know the definition of each option. The definition of each option is given below:
1. Synthesis reaction is a reaction in which two different elements or compound combine together to produce a new compound different from the two starting elements or compound. An example is illustrated below:
C + D —> E
2. Single replacement reaction is a reaction in which an element replaces or displaces another element in a compound. An example is illustrated below:
D + BC —> B + CD
3. Combustion reaction is a reaction in a substance react with oxygen to generate carbon dioxide (CO₂) and water (H₂O). An example can be seen when organic compound react with oxygen to produce carbon dioxide (CO₂) and water (H₂O). This is illustrated below:
CₓHᵧ + (x + y/4) O₂ —> xCO₂ + (y/2) H₂O
4. Double replacement reaction is a reaction in which the ions of the two reacting compound replaces one another to form new products. This is illustrated below:
X⁺Y¯ + U⁺V¯ —> X⁺V¯ + U⁺Y¯
5. Decomposition reaction is a reaction in which a large compound breaks down into two or more elements or compound. An example is illustrated below:
GH —> G + H
Now, observing the equation given in the question above:
Sn + 2HCl —> SnCl₂ + H₂
We can see that Sn replaces H in HCl to produce SnCl₂.
Therefore, the reaction is a single replacement reaction.
To eliminate the carbon dioxide pollutants, the factory manager should employ unit operations for CO2 capture. One example is through absorption process by using commercial CO2 absorbents like soda lime.
Here is the answer of the given question
