The value of for barium carbonate is .
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 . 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:
The expression to calculate the solubility product for the general reaction is as follows:
Here,
is the solubility product constant.
is the concentration of ions.
is the concentration of ions.
The dissociation of occurs as follows:
The given solubility of is 0.0100 g/L. Firstly, it is to be converted in mol/L. So the solubility of is calculated as follows:
…… (1)
The solubility of is 0.0100 g/L.
The molar mass of is 197.3 g/mol.
Substitute these values in equation (1).
It is evident from the chemical equation, one mole of dissociates to form one mole of and one mole of . So the solubility of both and is 0.00005068 mol/L.
The formula to calculate the solubility product of is as follows:
…… (2)
Substitute 0.00005068 mol/L for and 0.00005068 mol/L for in equation (2).
Therefore, the value of for is .

An excited state electron configuration of Gallium (Ga) might be [Ar] 4s2 3d9 4p2, as this configuration represents an electron having absorbed energy and moved from the 3d to the 4p level.
The electron configuration of an atom in its ground state is the arrangement of electrons in the lowest possible energy levels (the 'normal' arrangement). For the element Gallium (Ga), the ground state electron configuration is [Ar] 4s2 3d10 4p1. However, when an atom is in an excited state, one or more electrons have absorbed energy and moved to a higher energy level. An electron configuration for an excited state of Gallium might look like [Ar] 4s2 3d9 4p2 as an electron from the 3d level has absorbed energy and moved to the higher 4p level.

Answer:
The net ionic equation for the reaction of solid iron with aqueous copper sulfate:
Explanation:
Solid iron = Fe
Copper sulfate =
In an aqueous solution of copper sulfate we have copper (II) ions and sulfate ions.
In an aqueous solution of ferrous sulfate we have ion (II) ions and sulfate ions.
Cancelling out the common ions from both sides, we get the net ionic equation:
