Answer: The pair of valence electrons that do not participate in the bonding are lone pairs.

Explanation:

There are 2 types of pair of electrons that are studied in the bonding. They are:

Bonding pairs: These pair of electrons participate in the bond formation. They exist as bonds in a molecule. They are also known as bond pairs.
Non-bonding pairs: These pair of electrons do not participate in the bond formation. They exist as lone pairs in a molecule.

Oxygen is the 8th element of the periodic table having electronic configuration of $1s^22s^22p^4$

Number of valence electrons = (2 + 4) = 6

Oxygen needs 2 electrons to complete its octet. When another oxygen combines, they share 2 electrons each forming a double bond.

The Lewis dot structure of oxygen molecule is given below.

Hence, the pair of valence electrons that do not participate in the bonding are lone pairs.

Answer:

Nonbonding pairs of electrons.

Explanation:

Both oxygen atoms in the diatomic molecule have two nonbonding pairs. This results in the oxygen molecule having a planar geometric shape. This is because nonbonding pairs repel each other are significant in determining the shape of a molecule.

It is logical to assume that they hydrogen ion concentration in an aqueous solution of a strong monoproctic acid equals the molarity of the acid because ions which are charged,for example ammonium ion (NH4+), which can be derived by the addition of a proton to a molecular base.

Carbon-14 has a half-life of approximately 5700 years. How much of a 1000g sample will be left undecayed and still radioactive a

Artist 52 [7]

Answer:

option C is correct (250 g)

Explanation:

Given data:

Half life of carbon-14 = 5700 years

Total amount of sample = 1000 g

Sample left after 11,400 years = ?

Solution:

First of all we will calculate the number of half lives passes during 11,400 years.

Number of half lives = time elapsed/ half life

Number of half lives = 11,400 years/5700 years

Number of half lives = 2

Now we will calculate the amount left.

At time zero = 1000 g

At first half life = 1000 g/2 = 500 g

At second half life = 500 g/2 = 250 g

Thus, option C is correct.

Oxygen has an electronegativity of 3.5, and carbon has an electronegativity of 2.5. how is charge distributed on an oxygen atom

vlabodo [156]

When oxygen has an electronegativity of 3.5, and carbon has an electronegativity of 2.5, then the oxygen atom would have a slightly negative charge. The oxygen atom in the carbon monoxide molecule would pull more electrons to its side since it has higher electronegativity making it slightly negative and the carbon would have a slightly positive charge as it would contain less electrons. This results to the formation of a polar molecule. A polar molecule is made when the molecule contains a slightly positive end and a slightly negative end. It would have a net dipole which is a result of the partial opposing charges in the molecule.

Which term names the concentration of salts dissolved in a liquid?

Viefleur [7K]

Hey there!
The answer is D, Salinity.
Salinity is the concentration of salt in water. Ocean water often has high salinity and this can contribute to things like upwelling and water density- but these all start from salinity.
Hope this helps!
