Answer: A COMPLEX ION contains (a central metal ion bound to one or more ligands).

Explanation: A complex ion is defined as an ion that is formed between a central metal ion and one or more surrounding ligands, molecules or ions that contain at least one lone pair of electrons. The formation of a complex ion from a metal ion and a ligand is based on Lewis acid - base reaction. The positively charged metal ion( example Cu2+) acts as a Lewis acid, and the ligand, with one or more lone pairs of electrons (example NH3), acts as a Lewis base.

An example of a complex ion is copper ammine ion,{[Cu(NH3)6]2+}.

Answer:

A complex ion contains a central metal ion bound to one or more ligands

Explanation:

A complex ion is consists of a central atom or ion, that is usually metallic, called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents.

An example of a complex ion is

[Co(NH3)6]3+

Please go through the attached file for a proper representation of the complex ion.

Answer:

  3.0×10⁻¹³ M

Explanation:

The solubility product Ksp is the product of the concentrations of the ions involved. This relation can be used to find the solubility of interest.

<h3>Equation</h3>

The power of each concentration in the equation for Ksp is the coefficient of the species in the balanced equation.

  Ksp = [Al₃⁺³]×[OH⁻]³

<h3>Solving for [Al₃⁺³]</h3>

The initial concentration [OH⁻] is that in water, 10⁻⁷ M. The reaction equation tells us there are 3 OH ions for each Al₃ ion. If x is the concentration [Al₃⁺³], then the reaction increases the concentration [OH⁻] by 3x.

This means the solubility product equation is ...

  Ksp = x(10⁻⁷ +3x)³

For the given Ksp = 3×10⁻³⁴, we can estimate the value of x will be less than 10⁻⁸. This means the sum will be dominated by the 10⁻⁷ term, and we can figure x from ...

  3.0×10⁻³⁴ = x(10⁻⁷)³

Then x = [Al₃⁺³] will be ...

  [\text{Al}_3^{\,+3}]=\dfrac{3.0\times10^{-34}}{10^{-21}}\approx \boxed{3.0\times10^{-13}\qquad\text{moles per liter}}

We note this value is significantly less than 10⁻⁷, so our assumption that it could be neglected in the original Ksp equation is substantiated.

__

<em>Additional comment</em>

The attachment shows the solution of the 4th-degree Ksp equation in x. The only positive real root (on the bottom line) rounds to 3.0×10^-13.

in chlorine gas, two chlorine atoms join to form a Cl2 (chlorine 2) molecule. How many pairs of valence electrons do the atoms s
vladimir2022 [97]
Since each Chlorine molecule is -1 and wants to gain an electron, 2 Chlorine atoms like to come together to form Cl2 by sharing 2 electrons each to form a single bond between the 2 atoms. Since both Chlornine has the same electronegativity, the bond is non-polar covalent since there electrons are evenly shared.

Electrons must be able to flow through a material in order for the material to conduct
djverab [1.8K]

The molecular structure of the solids has lower ability to conduct electricity due to tight holding by nucleus.

<h3>Why molecular solids are poor conductors?</h3>

Molecular solids are also poor conductors of electricity because their valence electrons are tightly held by the nuclear charges present in the nucleus while on the other hand, Metals are good electrical conductors in the solid form due to the presence of free electrons that helps in the conduction of electricity.
