Argon (Ar): [Ne]3s23p6 core electrons valence electrons

Answers

Answer:

1. The core electrons are 10

2. The valence electrons are 8

Explaination:

Core electrons are electrons located in  the inner shells of and atom.

Valence electrons are electrons located on the outermost shell of an atom

From the question given above, we obtained:

Ar (18) => [Ne] 3s²3p⁶

Recall

Ne (10) => 1s² 2s²2p⁶

Therefore,

Ar (18) => [1s² 2s²2p⁶] 3s²3p⁶

From the above illustration,

Inner shell (core shell) => 1s² 2s²2p⁶

Outermost shell (valence shell) => 3s²3p⁶

1. Determination of the core electrons

Inner shell (core shell) => 1s² 2s²2p⁶

Core electrons = 2 + 2 + 6

Core electrons = 10

2. Determination of the valence electrons

Outermost shell (valence shell) => 3s²3p⁶

Valence electron = 2 + 6

Valence electron = 8

Answer:

10 core electrons

8 valence electrons

a micro meter is 10^-6 meter

frequency of light times wavelength = c  the speed of light 3X10^8 M/sec

so

frequency times 13 X10^-6 =3X10^8  M/

so

Answers

Explanation:

The difference between heat and thermal energy is that thermal energy is not in the process of being transferred; it is not in transit, but remains as part of the internal energy of the system; heat, on the other hand, is energy in transit, i.e. energy in the process of being transferred from a hotter system.

Help please witb this

Answers

Answer:

9

Explanation:

In a chemical equation, the subscript numbers next to each element's symbol tell us how many atoms of that element are in the substance. So, for example, in H₂O, there are 2 atoms of hydrogen since there is a "₂" next to the H.

What's next to our H in C₄H₉? It looks like "₉," so we can determine that there are 9 hydrogen atoms in C₄H₉ (which is butyl, by the way).

a solution of HCI contains 36 percent HCI,by mass and calculate the mole fraction of HCI in the solution?​

Answers

Explanation:

You have a solution that contains 36 g HCl dissolved in 64 g water

Molar mass HCl = 36.45 g/mol

Mol HCl in 36 g = 36 g / 36.45 g/mol = 0.9876 mol

Molar mass H2O = 18 g/mol

Mol H2O in 64 g = 64 g / 18 g/mol = 3.5556 mol

Total mol = 0.9875 + 3.5556 = 4.5431 mol

Mol fraction HCl = 0.9876 mol / 4.5431 mol = 0.2174

Mol fraction H2O = 3.5556 / 4.5431 = 0.7826

The answer should have 2 significant digits:

Mol fraction HCl = 0.22

Mol fraction H2O = 0.78

Mol fraction has no units.

2. Why was sud production used to assess the effectiveness of the synthesized soaps?

Answers

Answer:

Soap is effective as a cleaning agent because it is amphiphilic; it is partly polar and partly nonpolar. ... The sodium ion of the soap is replaced by one of these new ions, and the resulting salt is no longer soluble.

Soap seems to be amphiphilic, or partially polar as well as partially nonpolar, it works well as a cleaning agent. Several of these newfound ions take the place of such soap's sodium ion, rendering the salt insoluble.

What is Soap?

Long chain fatty acids are salts of sodium and potassium that have a cleaning effect in the water. referred as soap They should be used as cleaning agents to get rid of oil and filth from garments and skin. As an illustration, stearic, oleic, as well as palmitic acids are used to create sodium stearate, sodium oleate, respectively sodium palmitate.

What is cleaning agent?

Cleaning agents, often known as hard-surface cleansers, are things that are used to get rid of debris from surfaces, such as dust, stains, foul odors, and clutter. Health, aesthetics, odor removal, and stopping the transfer of dirt and toxins to oneself or others will be among the goals of cleaning products.

Because soap can serve as an emulsifying agent, it would be a superior cleanser. An emulsifier has the ability to mix two immiscible liquids together.

How do atomic and molecular interactions explain the properties of matter that we see and feel

Answers

The atomic and molecular interactions unveil the bulk properties of matter in our environment by ways of the fact that everything in the whole universe is made of either atoms, molecules or even ions

How matter is made up of atoms and molecules?

It has been proven practically everything in the whole universe is matter and everything which interact with matter is also matter. This explains to us the reasons why matter could be atoms, molecules or ions.

That being said, some substances (matter) is made up of atoms of elements, some made up of molecules or atoms and molecules and others ions or both. However, matter is anything which has mass and occupies space.

In conclusion, we can now conclude from the explanation above that the properties of matter are as a result of the interaction which exists between matter at the atomic and molecular level.
