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:

\boxed{{{\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}}.

It's simple, just follow my steps.

1º - in 1 L we have 0.0100~g of BaCO_3

2º - let's find the number of moles.

\eta=\frac{m}{MM}

\eta=\frac{0.0100}{197.3}

\boxed{\boxed{\eta=5.07\times10^{-5}~mol}}

3º - The concentration will be

C=5.07\times10^{-5}~mol/L

But we have this reaction

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

This concentration will be the concentration of Ba^{2+}~~and~~CO_3^{2-}

K_{sp}=\frac{[Ba^{2+}][CO_3^{2-}]}{[BaCO_3]}

considering [BaCO_3]=1~mol/L

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

and

[Ba^{2+}]=[CO_3^{2-}]=5.07\times10^{-5}~mol/L

We can replace it

K_{sp}=(5.07\times10^{-5})*(5.07\times10^{-5})

K_{sp}\approx25.70\times10^{-10}

Therefore the K_{sp} is:

\boxed{\boxed{\boxed{K_{sp}\approx2.57\times10^{-11}}}}

Zinc wire is added to an iron(II) nitrate solution.
Advocard [28]

Answer:

Zn(s) + Fe(NO₃)₂(aq) ⇒ Zn(NO₃)₂(aq) + Fe(s)

Explanation:

When metal zinc is added to an iron (II) nitrate solution, we can see the following redox reaction:

Zn(s) + Fe(NO₃)₂(aq) ⇒ Zn(NO₃)₂(aq) + Fe(s)

Zinc is oxidized since its oxidation number increases from 0 to +2.

Iron is reduced since its oxidation number decreases from +2 to 0.
