Explanation:

The given equation is as follows.

       PbBr_2 \rightleftharpoons Pb^{2+} + 2Br^{-}

                          s       2s

It is given that,

       K_{sp} = [Pb^{2+}][Br^{-}]^{2} = 6.60 \times 10^{-6}

Let the solubility of given ions be "s".

Since, KBr on dissociation will given bromine ions.

Hence,  K_{sp} = [Pb^{2+}] \times ([Br^{-}])^{2}

        6.60 \times 10^{-6}  = s \times (2s)^{2}

                        = 1.18 \times 10^{-2} M

Therefore, solubility of [PbBr_{2}] is 1.18 \times 10^{-2} M  in KBr.

Now, we will calculate the molar solubility of PbBr_{2} in 0.5 M KBr solution as follows.

           K_{sp} = (s) \times (2s + 0.5)^{2}

  6.60 \times 10^{-6}  = 4s^{3} + 0.25s + 2s^{2}

                         s = 2.63 \times 10^{-5}

Thus, we can conclude that molar solubility of [PbBr_{2}] in 0.500 m KBr solution is 2.63 \times 10^{-5}.

Three other application of Bernoulli's principle ?
Makovka662 [10]
<h2><u>Answer:</u></h2>

Bernoulli's Theorem in a general sense relates the weight, speed, and rise in a moving fluid (liquid or gas), the compressibility and consistency (internal grinding) of which are insignificant and the flood of which is predictable, or laminar.

(1): We can discover the speed of Efflux of a fluid.

This is given by v= sqrt (2gh), where the fluid is turning out from an opening in a vessel at profundity h from free fluid surface. This condition is known as Torricelli's hypothesis.

(2): Vena Contracta: The fluid stream from gap contracts at a separation minimal outside the opening to a neck, called Vena Contracta.

The territory of cross-segment of a fly is littler than a zone of opening. From this reality, we can discover the coefficient of withdrawal.

(3) : Bernoulli's standard is utilized in the development of Venturimeter, an instrument for estimation of measure of a stream of a fluid through a pipe.

Elena L [17]

Answer:

Engineering is all about solving problems using math, science, and technical knowledge. And engineers have solved a lot of problems in the world by designing and building various technologies. We have everything from machines that can breathe for you in hospitals to suspension bridges to computers we use every day. All of these things were once designed by engineers using the engineering design process.
