Answer:
it allows us to determine what substances will float and what substances will sink when placed in a liquid.
AB₂(s) ⇄ A²⁺(aq) + 2B⁻(aq)
Ksp=[A²⁺][B⁻]²
a=1.10 g/L
M=169 g/mol
c=a/M
[A²⁺]=c=a/M
[B⁻]=2c=2a/M
Ksp=(a/M)(2a/M)²=4(a/M)³
Ksp=4*(1.10/169)³=1.103×10⁻⁶
So for this, you would write the reaction. Since you have an element by itself, and a salt, it’s definitely a single-replacement reaction. So.........
Al + AgCl —-> Ag + AlCl3
Your products should be Silver and Aluminum Chloride.
