Answer:
1.44 mol
Explanation:
Given data:
Mass of Cu = 46 g
Moles of Ag produced = ?
Solution:
Chemical equation:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
Number of moles of Cu:
Number of moles = mass/ molar mass
Number of moles = 46 g/63.546 g/mol
Number of moles = 0.72 mol
Now we will compare the moles of Cu and silver from balance chemical equation:
Cu : Ag
1 : 2
0.72 : 2×0.72 = 1.44 mol
Thus from 46 g of Cu 1.44 moles of Ag is produced .
Answer:

Explanation:
Hello!
In this case, since the pH of the given metal is 10.15, we can compute the pOH as shown below:

Now, we compute the concentration of hydroxyl ions in solution:
![[OH^-]=10^{-pOH}=10^{-3.95}=1.41x10^{-4}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D10%5E%7B-pOH%7D%3D10%5E%7B-3.95%7D%3D1.41x10%5E%7B-4%7DM)
Now, since this hydroxide has the form MOH, we infer the concentration of OH- equals the concentration of M^+ at equilibrium, assuming the following ionization reaction:

Whose equilibrium expression is:
![Ksp=[M^+][OH^-]](https://tex.z-dn.net/?f=Ksp%3D%5BM%5E%2B%5D%5BOH%5E-%5D)
Therefore, the Ksp for the saturated solution turns out:

Best regards!
It would roughly be 16,404 feet. Or if you wanted to be more specific 16,404.2. I hope this helps.
