Inert gases are group 18 elements. They have there valance shell completely filled, hence they donot undergo chemical reactions under normal conditions.

Following are the list of inert gases, along with their application:

Helium:Used as component of breathing gases due to its poor solubility in fluids or lipids. Helium is used in low temperature cryogenics.

Neon: Neon finds widespread applications in daily life such as lights, fog lights, TV cine-scopes, lasers, luminous warnings etc.

Argon: Argon is used in electrical components to provide a protective heat transfer medium for semiconductors. Argon is also capable to fill fluorescent and incandescent light bulbs. It assist in providing blue light.

Krypton: Krypton are usually mixed with a halogen to produce excimer lasers

Xenon: It is possible to generate X-rays from Xe. When Xe mixed with oxygen, it has to capability to enhance the contrast in CT imaging.

Radon: Radon is a radioactive element, which is used for radiotherapy and relief from arthritis.

Noble gases/inert gases are used in various fields including lamp fillers, metal welding or coolers

Further explanation

Noble gas (group 8A in the periodic system the element) is an element that is not reactive (stable) /inert

Its stability is caused by:

1. ns² np⁶ electron configuration (except He: 1s2), electrons in the subshell are already paired, making it difficult to form bonds with other elements

2. High ionization energy making it difficult to form positive ions (ionic compounds)

3. Low electron affinity that makes it difficult to bind electrons to become negative ions

Some noble gases such as Ar, Kr are obtained from multilevel distillation

The use of noble gases include:

1. Helium: filler of a gas balloon, mix with oxygen in a diver's tube, coolant
2. Neon: filler lights in red, can penetrate the fog
3. Argon: metal welding
4. Krypton and Xenon: colorful lights

To understand the relation between the strength of an acid or a base and its pKa and pKb values. The degree to which a weak acid

elena-14-01-66 [18.8K]

Answer:

pKa = 3.675

Explanation:

pKa = - Log Ka

∴ C X-281 = 0.079 M

∴ pH = 2.40

let X-281 a weak acid ( HA ):

∴ HA ↔ H+ + A-

⇒ Ka = [H+] * [A-] / [HA]

mass balance:

⇒ C HA = 0.079 M = [HA] + [A-]

⇒ [HA] = 0.079 - [A-]

charge balance:

⇒ [H+] = [A-] + [OH-]... [OH-] is negligible; it comes from to water

⇒ [H+] = [A-]

∴ pH = - log [H+] = 2.40

⇒ [H+] = 3.981 E-3 M

replacing in Ka:

⇒ Ka = [H+]² / ( 0.079 - [H+] )

⇒ Ka = ( 3.981 E-3 )² / ( 0.079 - 3.981 E-3 )

⇒ Ka = 2.113 E-4

⇒ pKa = - Log ( 2.113 E-4 )

⇒ pKa = 3.675

What is Y? 222/86 Rn A/z + 4/2He

kondaur [170]

$^{222}_{\phantom{2}86}\text{Rn} \to ^{218}_{\phantom{2}84}\text{Po}+ ^{4}_{2}\text{He}$

Y is Po-218.

A = 218
Z = 84.

<h3>Explanation </h3>

$^{222}_{\phantom{2}86}\text{Rn} \to ^{A}_{Z}\text{Y}+ ^{4}_{2}\text{He}$

Here's the symbol of a particle in a nuclear reaction. $^{A}_{Z}\text{Y}$ .

A stands for mass number. Z stands for atomic number. Both numbers shall conserve in a nuclear reaction.

The mass number on the left hand side is 222.
The two mass numbers on the right hand side add up to A + 4.
222 = A + 4.
A = 218

So is the case for the atomic number. Try figure out the atomic number of Y using the same approach.

The atomic number on the left hand side is 86.
The two atomic number on the right hand side add up to __ + __.
86 = __ + __.
Z = 84.

What element is Y? The atomic number of Y is 84. Refer to a periodic table. Element 84 corresponds to Po (polonium). Y is Polonium-218. The symbol of Y should be written as $^{218}_{\phantom{2}84}\text{Po}$ . Hence the equation:

$^{222}_{\phantom{2}86}\text{Rn} \to ^{218}_{\phantom{2}84}\text{Po}+ ^{4}_{2}\text{He}$ .
