Answer:
1. 0.97 V
2. 
Explanation:
In this case, we can start with the <u>half-reactions</u>:
With this in mind we can <u>add the electrons</u>:
<u>Reduction</u>
<u>Oxidation</u>
The reduction potential values for each half-reaction are:
- 0.69 V
-1.66 V
In the aluminum half-reaction, we have an oxidation reaction, therefore we have to <u>flip</u> the reduction potential value:
+1.66 V
Finally, to calculate the overall potential we have to <u>add</u> the two values:
1.66 V - 0.69 V = <u>0.97 V</u>
For the second question, we have to keep in mind that in the cell notation we put the anode (the oxidation half-reaction) in the left and the cathode (the reduction half-reaction) in the right. Additionally, we have to use "//" for the salt bridge, therefore:
I hope it helps!
Answer:
B
Explanation:
Energy is released, when a gas changes to solid
Answer is option D. All of these choices are correct.
<u>Explanation</u>:
SNP or single nucleotide polymorphism is a location that showcases the difference in individual alleles by one base pair. Mainly, a genetic difference that happens between different individuals.
It is the most common variation in genetics among people. Further, every SNP represents the difference in single DNA building block known as a nucleotide. Many SNPs do not affect the health of a person. It helps in predicting a response of a person to drugs.
