Answer:
1. 0.97 V
2. ![Al_(_s_)/Al^+^3~_(_a_q_)~//~Ag^+~_(_a_q_)/Ag_(_s_)](https://tex.z-dn.net/?f=Al_%28_s_%29%2FAl%5E%2B%5E3~_%28_a_q_%29~%2F%2F~Ag%5E%2B~_%28_a_q_%29%2FAg_%28_s_%29)
Explanation:
In this case, we can start with the <u>half-reactions</u>:
![Ag^+~_(_a_q_)->~Ag_(_s_)](https://tex.z-dn.net/?f=Ag%5E%2B~_%28_a_q_%29-%3E~Ag_%28_s_%29)
![Al_(_s_)~->~Al^+^3~_(_a_q_)](https://tex.z-dn.net/?f=Al_%28_s_%29~-%3E~Al%5E%2B%5E3~_%28_a_q_%29)
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:
![Al_(_s_)/Al^+^3~_(_a_q_)~//~Ag^+~_(_a_q_)/~Ag_(_s_)](https://tex.z-dn.net/?f=Al_%28_s_%29%2FAl%5E%2B%5E3~_%28_a_q_%29~%2F%2F~Ag%5E%2B~_%28_a_q_%29%2F~Ag_%28_s_%29)
I hope it helps!

Explanation:
reaction equations to make connections between the reactants and products in reactions. ... pathway: mol of O2 → mol of H2O → grams of H2O. 3.5 mol ... 25 g KClO3 ... How many grams of hydrogen gas are produced from the reaction of 221.
Answer:
Genetic factors contributes to the formation of the dead zones is by their ability to expand their abilities that enables them to spread and contribute to the formation of the dead zones. These dead zones are made when the oxygen are low where it is necessarily important for the aquatic life, if the oxygen needed is depleted or too low, instead of supporting aquatic life, dead zones are created and factors contribute to these occurrences with their ability to expand.
Explanation:
It is not equal because it dose not obey the conservation of mass. 60+25= 85 not 75.
