<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:
Number mole of calcium (Ca) = 1.4942 x 10⁻⁷ (Approx.)
Explanation:
Given:
Number of atom in (Ca) = 9 x 10¹⁶
Find:
Number mole of calcium (Ca)
Computation:
Number mole of calcium (Ca) = Number of atom in (Ca) / Avogadro's number
Number mole of calcium (Ca) = (9 x 10¹⁶) / (6.023 x 10²³)
Number mole of calcium (Ca) = 1.4942 x 10⁻⁷ (Approx.)
Is 29x the facts of 14 easy
The answer would be soluble. Think of it like salt. On it's own it is the white substance that you can see, but when you put it in water and stir it disappears. It is still there, but the physical appearance has changed. Also being explosive, flammable, and reactive are all chemical properties. Hope this helped!
