Hello there!
In this case, since the the concentrations are not given, and not even the Ksp, we can solve this problem by setting up the chemical equation, the equilibrium constant expression and the ICE table only:
Next, the equilibrium expression according to the produced aqueous species as the solid silver chloride is not involved in there:
![Ksp=[Ag^+][Cl^-]](https://tex.z-dn.net/?f=Ksp%3D%5BAg%5E%2B%5D%5BCl%5E-%5D)
And therefore, the ICE table, in which x stands for the molar solubility of the silver chloride:
I - 0 0
C - +x +x
E - x x
Which leads to the following modified equilibrium expression:
Unfortunately, values were not given, and they cannot be arbitrarily assigned or assumed.

When magnesium ion doesn't give any characteristics colour with the flame test as electronic transisitons do not give out visible light.
Those substances which has pH less than 5 are more acidic than Honeybee Venom. Some of them are listed below along with their pH scale,
1) <span>Acid rain and Tomato Juice has a pH of 4.
2) Soda and Orange Juice has a pH of 3.
3) Vinegar and Lemon Juice has pH of 2.
4) Gastric acid has a pH of 1.
5) Battery Acids have pH of zero.</span>
Answer:
A ) 1, 2 and 3
Explanation:
1 ) is correct because,
K donates 1 electron
F gain 1 electron from K.
If donating and gaining of electrons takes place between two electron, then type of compound formed is ionic.
2 ) is correct because,
K + F -----> KF
3 ) is correct because,
KF is soluble in cold water; very soluble in hot water.
