Answer:

The two atoms will contribute and share two electrons each in a double covalent bond, to form a molecule of the element.

Explanation:

Following the rule which says that an octet structure in the valence electrons shell of an atom, when two atoms of an element with the electronic configuration 1s²2s²2p⁴ comeclose to each other, they will share there electrons in covalent bonding to form a molecule, and thus attain stability by achieving an octet structure.

An atom of the element with electronic configuration 1s²2s²2p⁴, has 6 valence electrons and thus, needs two more electrons in order to achieve an octet. This is achieved by sharing two electrons with another atom of the same element which contributes two electrons as well to form a double covalent bond and a molecule of the element. Therefore, each atom would then have an octet structure in their valence shells.

Answer:

$K_{c} = [\text{C}]^{2}[\text{[D]}$

Explanation:

$\rm A(s)+3B(l) \, \rightleftharpoons \, 2C(aq)+D(aq)$

The general formula for an equilibrium constant expression is

$K_{c} = \dfrac{[\text{Products}]}{[\text{Reactants}]}$

Solids and liquids are not included in the equilibrium constant expression.

Thus, for this reaction,

$K_{c} = [\textbf{C}]^{\mathbf{2}}\textbf{[D]}$

When bacteria are decomposing animal waste, the level of ___________ rises. phosphate nitrate nitrite dissolved oxygen ammonia t

AlekseyPX

Decomposition is the process of degradation or break down of organic matter such as cellulose or other polysaccharide to simpler unit or monosaccharide. Usually decomposition takes place in absence of oxygen such as anaerobic decomposition. The decomposition results in evolution of carbon dioxide by degrading the C , H and O of organic matter with the help of bacterias ro microorganisms.

Thus, with decomposition, the level of carbon dioxide increases.

Write the symbolic notation of an isotope of an element having 8 protons, 8 electrons, and 11 neutrons. Click on the “Templates”

horrorfan [7]

Attached to this answer is the format of Isotope Notation that you can use for future reference. (Please open)

There are 8 Protons. The Atomic Number is the same number of an element's proton.

If you can see in the format, the mass number is calculated by adding the atomic number/protons and neutrons.

Mass number = 8 + 11
Mass number = 19

The image of the final answer is attached as well.
