Answer: 4.5 moles of 
can be made from complete reaction of 3.0 moles of Al.
Explanation:
The given reaction equation is as follows.
This shows that 2 moles of Al reacts with 6 moles of HCl. So, the amount of HCl required to react with 1 mole Al is three times the amount of HCl.
Therefore, 3 moles of Al will react with 9 moles of HCl to give 3 moles of 
and 
moles of .
The reaction equation now will be as follows.
The moles can also be written as 4.5 moles.
Thus, we can conclude that 4.5 moles of can be made from complete reaction of 3.0 moles of Al.
Answer:
The answer to your question is pH = 9.08
Explanation:
Data
pH = ?
Concentration = 1.2 x 10⁻⁵ M
Process
1.- Calculate the pOH of the solution
Formula
pOH = -log[OH⁻]
pOH = -log[1.2 x 10⁻⁵]
pOH = 4.92
2.- Calculate the pH
Formula
pH = 14 - pOH
Substitution
pH = 14 - 4.92
Result
pH = 9.08
