Answer : The value of K_{sp} is, 2.57\times 10^{-9}

Explanation :

First we have to calculate the solubility in mole/L.

Solubility=\frac{0.01g/L}{197.3g/mole}=5.07\times 10^{-5}mole/L

The balanced equilibrium reaction will be,

BaCO_3\rightleftharpoons Ba^{2+}+CO_3^{2-}

The expression for solubility constant for this reaction will be,

K_{sp}=[Ba^{2+}][CO_3^{2-}]

K_{sp}=(s)\times (s)

K_{sp}=(s)^2

Now put the value of solubility in this expression, we get the K_{sp} of barium carbonate.

K_{sp}=(5.07\times 10^{-5})^2

K_{sp}=2.57\times 10^{-9}

Therefore, the value of K_{sp} is, 2.57\times 10^{-9}

The value of {{\text{K}}_{{\text{sp}}}} for barium carbonate is \boxed{{\text{2}}{{.6 \times 1}}{{\text{0}}^{{\text{ - 9}}}}}.

Further explanation:

Solubility product constant:

The equilibrium constant between the compound and its ion, when dissolved in solution, is known as solubility product constant. It is denoted by {{\text{K}}_{{\text{sp}}}}. The solubility product constant is used to calculate the product of the concentration of ions at equilibrium. Higher the solubility product constant more will be the solubility of the compound.

The general reaction is as follows:

{\text{AB}}\left({aq}\right)\to{{\text{A}}^+}\left({aq}\right)+{{\text{B}}^-}\left({aq}\right)

The expression to calculate the solubility product for the general reaction is as follows:

{{\text{K}}_{{\text{sp}}}}=\left[{{{\text{A}}^+}}\right]\left[{{{\text{B}}^-}}\right]

Here,

{{\text{K}}_{{\text{sp}}}} is the solubility product constant.

\left[ {{{\text{A}}^ + }} \right] is the concentration of {{\text{A}}^+}ions.

\left[ {{{\text{B}}^ - }} \right]is the concentration of {{\text{B}}^ - }ions.

The dissociation of {\text{BaC}}{{\text{O}}_{\text{3}}} occurs as follows:

{\text{BaC}}{{\text{O}}_3}\to{\text{B}}{{\text{a}}^{2+}}+{\text{CO}}_3^{2-}

The given solubility of {\text{BaC}}{{\text{O}}_{\text{3}}} is 0.0100 g/L. Firstly, it is to be converted in mol/L. So the solubility of {\text{BaC}}{{\text{O}}_{\text{3}}} is calculated as follows:

{\text{Solubility of BaC}}{{\text{O}}_{\text{3}}}\left( {{\text{mol/L}}}\right)= \frac{{{\text{Solubility of BaC}}{{\text{O}}_{\text{3}}}\left( {{\text{g/L}}}\right)}}{{{\text{Molar mass of BaC}}{{\text{O}}_{\text{3}}}\left( {{\text{g/mol}}}\right)}}          …… (1)

The solubility of {\text{BaC}}{{\text{O}}_{\text{3}}} is 0.0100 g/L.

The molar mass of {\text{BaC}}{{\text{O}}_{\text{3}}} is 197.3 g/mol.

Substitute these values in equation (1).

\begin{aligned}{\text{Solubility of BaC}}{{\text{O}}_{\text{3}}}&=\left({\frac{{{\text{0}}{\text{.0100 g}}}}{{{\text{1 L}}}}} \right)\left( {\frac{{{\text{1 mol}}}}{{{\text{197}}{\text{.3 g}}}}}\right)\\&=0.00005068\;{\text{mol/L}}\\\end{aligned}

It is evident from the chemical equation, one mole of {\text{BaC}}{{\text{O}}_{\text{3}}} dissociates to form one mole of {\text{B}}{{\text{a}}^{2 + }} and one mole of {\text{CO}}_3^{2 - }. So the solubility of both {\text{B}}{{\text{a}}^{2 + }} and {\text{CO}}_3^{2-}is 0.00005068 mol/L.

The formula to calculate the solubility product of  is as follows:

{{\text{K}}_{{\text{sp}}}}=\left[{{\text{B}}{{\text{a}}^{{\text{2+}}}}}\right]\left[ {{\text{CO}}{{_3^2}^-}}\right]                   …… (2)

Substitute 0.00005068 mol/L for\left[{{\text{B}}{{\text{a}}^{{\text{2+}}}}}\right] and  0.00005068 mol/L for \left[ {{\text{CO}}_3^{2 - }} \right]in equation (2).

\begin{aligned}{{\text{K}}_{{\text{sp}}}}&=\left( {{\text{0}}{\text{.00005068}}} \right)\left( {{\text{0}}{\text{.00005068}}} \right)\\&=2.6\times{10^{-9}}\\\end{aligned}

Therefore, the value of {{\mathbf{K}}_{{\mathbf{sp}}}} for {\mathbf{BaC}}{{\mathbf{O}}_{\mathbf{3}}} is {\mathbf{2}}{\mathbf{.6 \times 1}}{{\mathbf{0}}^{ - 9}}.

What is the approximate geometry around each oxygen atom
AnnyKZ [126]

Answer:

correct option: A. tetrahedral

Explanation:

when we talk about hydrogen bonding in water due to oxygen then need to check the number of lone pair available for hydrogen bonding because hydrogen bond form between lone pair of oxygen and hydrogen of other water molecule so there are two lone pair which forms hydrogen bond and there are also two other covalent bond with hydrogen of same molecule so total number is 4 it means they will form a tetrahedral geometry

Which process would require the least amount of energy?
Aleksandr [31]
Answer:<span> a) the process for the first ionization energy
</span>
<span>Every time you take a electron you're requiring more and more energy. Expelling the first one will require less energy than expelling the second and the second will require less than the third, and so on.
When you take the first one, the atom becomes positive and with that the negative forces of the electron will be more attracted to the positive charge. The more electrons that are lost, the more positive this ion will become, causing it to be more difficult to separate the electrons from the atom.

Consider the heating curve for water. A graph of the heating curve for water has time in minutes on the horizontal axis and Temp
Zolol [24]

Answer:

0°C.

Explanation:

Hello,

In this case, given the heating curve of water on the attached document, we can notice that at 0 °C the solid starts melting, which means that the melting point is reached. Melting point is known as a physical change whereby a solid changes to liquid by the addition of heat as it allows the molecules to separate to each other.

Best regards.
