Answer:

Find the explanation below.

Explanation:

Sentence A: In sentence A, the bolded words create a positive undertone to the entire meaning of the text. Words such as unimaginable accomplishment, stunning, and fascinated produce a pleasing and heartening mood. They make it clearer to the reader that this action by the scientists elicited a favorable response from the viewers.

Sentence B: In sentence B, there is a negative undertone to the text. The use of descriptors such as shocking, recklessly, alarmed, tells the reader of the unfavorable response the action of the scientists produced in the viewers. A gloomy mood is thus created.

Consider the calculation of the pressure in kilopascals exerted by 1.25 g of nitrogen gas in a flask of volume 250 mL (0.250 dm3

Harrizon [31]

The amount of the nitrogen gas, N₂ molecules present is 2.68×10²² molecules

<h3>Avogadro's hypothesis </h3>

1 mole of N₂ = 6.02×10²³ molecules

<h3>How to determine the mole of N₂</h3>

We'll begin by calculating the number of mole of N₂. This can be obtained as follow:

Mass of N₂ = 1.25 g
Molar mass of N₂ = 28.02 g/mol
Mole of N₂ =?

Mole = mass / molar mass

Mole of N₂ = 1.25 / 28.02

Mole of N₂ = 0.0446 mole

<h3>How to determine the molecules of N₂ present</h3>

From Avogadro's hypothesis,

1 mole of N₂ = 6.02×10²³ molecules

Therefore,

0.0446 mole N₂ = 0.0446 × 6.02×10²³

0.0446 mole N₂ = 2.68×10²² molecules

Thus, the molecules of N₂ present is 2.68×10²² molecules

The name of that product is 1-nonene.

The sufix ene is because it is an alkene, which comes from the fact that it has a double bond.

The prefix none is because it has 9 carbon.

And the use of number 1 is because the double bond is in the carbon number 1.

When we looked at assigning the electrons in nitrogen to sites in the 2s and 2p orbitals, we used the 2s anti-bonding site. Whic

AveGali [126]

Answer:

B) Although this site is not desirable for making a bond between atoms, it is a good site in the sense that the electrons can be close to the nucleus.

Explanation:

An antibonding orbital points away from the nuclei, with a node between them, so the electrons are not held close to the nuclei. The orbital is not desirable for bonding.

The diagram below shows a σ*1s molecular orbital, but a σ*2s orbital has a similar shape.

A) is true. The σ*1s orbital has the lowest energy.

C) is true. Any orbital can accommodate at most one electron pair.

D) is may be true. Orbital energy decreases as atomic number increases, so the orbital energy of an N₂ σ*2s molecule may be close to that of a sulfur atom's 2s orbital.
