The balance chemical reaction is
<span><span>2Al + 6HCl -</span>à 2AlCl3 + 3H2</span>
A
ssuming excess amount of HCl because it is not given
Mole Al reacted = 13.5 g ( 1 mole/ 27 g)
= 0.5 mole Al
Mole H2 = 0.5 mol Al ( 3 mole H2 / 2 mole Al)
<span> =
0.75 mole H2</span>
since at STP then 1 mole gas occupies 22.414 L
volume H2 = 0.75 mole (22.414 L / mol)
<span>= 16.8105 L H2</span>
Diamonds are common in the making of jewelry, but they are also used industrially because of their hardness. They are extremely useful in cutting, grinding, and drilling other materials.
This process is named taxonomy.
