The unit cell of Aluminum is a face-centered cubic structure. This lattice unit cell consists of 4 atoms per unit cell. The volume of the unit cell is a³ where a is the length of the side of the unit cell. In terms of radius r, volume is equal to:
V = (4r/√2)³
V = (4(0.143×10⁻⁹ m)/√2)³
V = 6.62×10⁻²⁹ m³
As metal + acid will form hydrogen gas and salt , the chemical equation is :
Mg + 2HCl --> H2 + MgCl2
<span>It's because the product formed with BF3 is more complex which able to decompose AlF3.
</span>AlF3 doesn't dissolve in HF because of the fluorine. It's doesn't allow for coordination due to the hydrogen. However, it will dissolve in KF. If you look at the chemical reaction, it's able to form a salt.
<span>3KF+Al<span>F3</span>−>3KF.Al<span>F3</span></span>
