Polygon ABCDE rotates 52 degrees around its axis to form polygon A'B'C'D'E'. If measure of angle BCD = 31 degrees, then 31 degrees will still be the right response for B'C'D'.

The polygon's form and angle won't change if it is rotated. Since a rotation is a hard transformation that finally retains angle measurements, the angle will remain 31 degrees even after the revolution.

A closed polygonal circuit or a polygonal chain is a plane figure that may be defined by a finite number of straight line segments connected to one another. We refer to a polygon as either a bounded circuit or a bounded plane region.

Determine the molar solubility of al(oh)3 in a solution containing 0. 05 m alcl3. Ksp for al(oh)3 is 1. 3 × 10-33.
Mariulka [41]

From the calculations carried out , we can see that the molar solubility of Al(OH)3 is 8.6 x 10^-12 M  

<h3>What is solubility?</h3>

The term solubility refers to the amount of substance that dissolves in a solution measured in moles per liter.

From the question we have initial  [Al+3] = 0.05 M

Setting up an ICE table:

             Al(OH)3(s) → Al3+  +  3OH-

I                                    0.05         0

C                                 +x           +3x

E                                0.05+x         3x

Know that;

Ksp = [Al3+] [OH-]^3

Ksp = 1.3 x 10^-33

So;

[Al3+] = (0.05+X) and [OH-]^3 = 3X

If x = molar solubility of Al(OH)3

Then:

1.3 x 10^-33 = (0.05 + X) (3X)^3 by solving for X

x = 8.6 X 10^-12 M
