<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.

Answer:
2H₂O (l) ⇄ H₃O⁺ (aq) + OH⁻(aq)
Explanation:
The autoionization of water is defined as a chemical reaction where there is an equilibrium in which two water molecules react producing an hydronium ion and a hydroxide ion. This is also defined as the autoprotolysis of water, and is based on its amphoteric nature.
The substance that can donate protons as well as receive them is defined as amphoteric. In this way, the water behaves amphoteric as it donates a proton as an acid of Brownsted Lowry or if it receives a proton, being a base.
NH₃ + H₂O ⇄ NH₄ + OH⁻ Kb
In this case, water behaves as an acid, it donates the proton to ammonia (a base)
CH₃COOH + H₂O ⇄ CH₃COO⁻ + H₃O⁺ Ka
For this case, water behaves as a base, it recieves the proton from the acetic acid (acid)

Answer:
<h2>15 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>15 m/s²</h3>
Hope this helps you
The second one is more concentrated as they both times with the same thing but the second one (1.5) is bigger
