Which elements have atoms that are likely to form an anion?

Chemistry
1 answer:
KengaRu [80]3 years ago
5 0
Answer:

Phosphorus, chlorine and selenium.

Explanation:

If you look at a periodic table, you will notice that phosphorus, chlorine and selenium are all in groups 15-17. Elements in these groups are more likely to gain electrons then they are to lose them, thus making them more likely to form an anion.
This is because they want to fill their outer valence shell of electrons so that they can have a full octet and for groups 15-17 it’s easier to gain 1-3 electrons then it is to loose 5-7 electrons.

A sample of gas occupies a volume of 445 mL at a temperature of 274 K. At what temperature will this sample of gas occupy a volu
Ksenya-84 [330]
V1 = 445ml V2 = 499ml
T1 = 274 K T2 = ?

By Charles Law,
V1/T1 = V2/T2
445/274 = 499/T2
By solving we get,
T2 = 307.25 K

Cis-4-tertButylcyclohexyl bromide (compound 1) and Trans-4 tert Butylcyclohexylbromide (compound 2) are reacted with Potassium T
Mkey [24]

Answer:

In compound 1 the Tert butyl group occupies the equatorial position and the Bromine occupies the axial position and in compound 2 the Tert butyl occupies the axial and the bromine occupies equatorial positions. Compound 1 reacts faster than compound 2.

Explanation:

In cyclic organic compounds, substituents may occupy the axial or equatorial positions. The axial positions are aligned parallel to the symmetry axis of the ring while the equatorial positions are around the plane of the ring.

Bulky substituents have more room in the equatorial than in the axial position. This means that compound 1 is more stable than compound 2.

This is clear on the basis of stability of the molecules because compound 1 will react faster than compound 2 since the bulky tertiary butyl group in compound 1 occupy equatorial and not axial positions.

IgorLugansk [536]

Answer:

<u><em>The correct answer is:</em></u>

<h3><u><em>Option D: Evapotranspiration  </em></u></h3>

<u><em>Water is removed both from the plants and the soil. Evapotranspiration is a process by which the water is removed from plants and ground and is added back into the atmosphere. From ground, water is removed in the form of evaporation from the soil. And from plants the water is removed by transpiration. Hence the term Evapotranspiration.</em></u>

why is iodine is a solid at STP but chlorine is a gas at STP? explain in terms of intermolecular forces.
Lerok [7]
Iodine is a solid at STP (standard room temperature and pressure) as the intermolecular forces between the iodide compound is strongly held by bonds such as electrostatic forces of attraction if its a ionic compound. Therefore STP is so sufficient enough to breakthrough these bonds hence its a solid. However, chlorine’s a gas as its intermolecular bonds are weak, and STP is strong enough to break these bonds of where chlorine is a gas


NOTE: they should really give you a compound so you can identify between covalent and ionic bonds and talk about it in more depth
