This is science what about this one? According to modern atomic theory, _____ can't move from one energy

1 answer:

5 0

According to modern atomic theory, electrons can't move from one energy
level to another. It is not that it cannot really move but electrons tend to stay at a level with the lowest energy possible. Hope this answers the question. Have a nice day.

Give the characteristics of a strong acid.has a polar bondhas a weaker bond to hydrogenhas equilibrium far to the rightionizes c

Dominik [7]

Answer:

All of the above

Explanation:

Give the characteristics of a strong acid.

Has a polar bond. YES. A big difference in the electronegativity between the heteroatom and the hydrogen atom is associated with the strength of an acid.

Has a weaker bond to hydrogen. YES. A weaker bond to hydrogen makes it easier for it to break.

Has equilibrium far to the right. YES. The equilibrium of a strong acid is very shifted towards the products.

Ionizes completely in aqueous solutions. YES. A strong acid exists mostly in the ionic form in aqueous solution.

There are ________ σ bonds and ________ π bonds in h3c-ch2-ch=ch-ch2-c≡ch.

FrozenT [24]

The number of sigma and pi bonds are,

Sigma Bonds = 16

Pi Bonds = 3

Explanation:
Every first bond formed between two atoms is sigma. Pi bond is formed when already a sigma bond is there. While in case of Alkyne (triple Bond) there is one sigma and one pi bond already present, so the third bond is formed by second side-to-side overlap of orbitals, hence, a second pi bond is formed.
Below all black bonds are sigma bonds, while in alkene there is one pi bond and in alkyne there are two pi bonds.

13. What is the molality of a solution with 18.4 moles LiF in 26 kg H2O? *

melisa1 [442]

Here, We are asked to calculate the molarity of a solution with 18.4 moles of Lithium Fluoride in 26 kg of water... To find the molarity, We need to divide the number of moles by the volume of solution in liters

»«»«»«»«»«»«»«»«»«»«»«»«»«»«»«»«»«»«»«»«»«»«»«»«»«»

Number of moles = 18.4
Volume of solution = 26 kg = 37.14 liters

$\tt \twoheadrightarrow \: molarity = \frac{number \: of \: moles}{volume \: of \: solution}$

$\tt \twoheadrightarrow\: molarity = \frac{18.4}{37.14}$

$\sf \Rrightarrow \: molarity = 0.71 \: molar$

➪ Therefore, The molarity of solution is 0.71 molar...~

Which layer of the atmosphere is between the exosphere and the mesosphere

Olenka [21]

The atmosphere of earth is made of five main layers.

1) Troposphere : This is the lowest part of the atmosphere. Most of the air that makes up the atmosphere is present in this layer.

2) Stratosphere : This layer is present above troposphere and extends up to 50 km. It contains ozone layer which prevents the harmful ultraviolet rays from the sun from entering the lower troposphere

3) Mesosphere : The layer above stratosphere is known as mesosphere.

4) Thermosphere : The region lies above mesosphere.

5) Exosphere : The is the outermost region of the atmosphere.

From the above discussion we can see that the layer that lies between exosphere and mesosphere is Thermosphere
