What are the substances of the Polar Covalent Bond?

1 answer:

3 0

The polar covalent bonding occurs when two atoms with different electronegativity form a covalent bond. This type of connection, the electrons are not equally shared. Typically, the atom having higher electronegativity attracts the electrons in the next link to it, thus forming a negative pole in its vicinity, and a positive pole of the next region less electronegative atom.
example: In the molecule HCl, hydrochloric acid, chlorine atom is more electronegative attracting electrons proximity to the bond with the hydrogen atom that is less electronegative, or more electropositive also rated.

hope this helps!.

The particle that adds mass but no charge to the atomic nucleus is the neutron.

The nucleus contains both protons and neutrons.

Protons and neutrons have about the same mass.

However, protons have a positive charge, while neutrons have no charge,

Copper(II) sulfide, CuS, is used in the development of aniline black dye in textile printing. What is the maximum mass of CuS wh

IrinaK [193]

Explanation:

The chemical reaction equation will be as follows.

$CuCl_{2} + (NH_{4})_{2}S \rightarrow 2NH_{4}Cl + CuS$

As 1 mole $CuCl_{2}$ reacts with 1 mole of $(NH_{4})_{2}S$

Hence, moles of $CuCl_{2}$ = Molarity × Volume (in mL)

= 0.5 × 38.0 mL

= 0.019 mol

Moles of $(NH_{4})_{2}S$ = Molarity × Volume (in mL)

= 0.6 × 42.0 mL

= 0.0252 mol

As moles of CuS is less than the moles of $(NH_{4})_{2}S$ . This means that CuS is the limiting reagent.

Thus, maximum moles of CuS formed are 0.019 mol. As molar mass of CuS is 95.6 g/mol.

Therefore, maximum mass of CuS can be formed is $95.6 g/mol \times 0.019 mol$

= 1.8164 g

Thus, we can conclude that maximum mass of CuS formed is 1.8164 g.

Integrated rate law for second order unimolecular irreversible

kirill115 [55]

Answer:

The rate law for second order unimolecular irreversible reaction is

$\frac{1}{[A]} = k.t + \frac{1}{[A]_{0} }$

Explanation:

A second order unimolecular irreversible reaction is

2A → B

Thus the rate of the reaction is

$v = -\frac{1}{2}.\frac{d[A]}{dt} = k.[A]^{2}$

rearranging the ecuation

$-\frac{1}{2}.\frac{k}{dt} = \frac{[A]^{2}}{d[A]}$

Integrating between times 0 to t and between the concentrations of $[A]_{0}$ to [A].

$\int\limits^0_t -\frac{1}{2}.\frac{k}{dt} =\int\limits^A_{0} _A\frac{[A]^{2}}{d[A]}$

Solving the integral

$\frac{1}{[A]} = k.t + \frac{1}{[A]_{0} }$

In what region of the periodic table will you find elements with relatively high IEs? With relatively low IEs?

Katarina [22]

Explanation:

When we find elements with high ionization energy in the upper right corner because the zeff experienced by the outer electron is high and electrons that are close to the nucleus.

The low Ionization energy elements are found in lower left where majority is of metals. The Zeff is low as the outer electrons are distance from the nucleus.
