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:
light is the result of electrons moving between defined energy levels in an atom called shells.
Explanation:
when something exited an atom like collision with another atom or a chemical reaction, an electron may absorb energy boosting it to a higher level shell.
