Answer:

Approximately [tex]1.7\; {\rm L}[/tex].

Explanation:

Nitrogen [tex]{\rm N_{2}}\, (g)[/tex] reacts with hydrogen [tex]{\rm H_{2}}\, (g)[/tex] at a [tex]1:3[/tex] ratio to produce ammonia [tex]{\rm NH_3}\, (g)[/tex]:

[tex]{\rm N_{2}}\, (g) + 3\; {\rm H_{2}}\, (g) \to 2\; {\rm NH_{3}}\, (g)[/tex].

The ratio between the coefficient of [tex]{\rm N_{2}}\, (g)[/tex] and the coefficient of [tex]{\rm H_{2}}\, (g)[/tex] is:

[tex]\begin{aligned}\frac{n({\rm N_{2}})}{n({\rm H_{2}})} = \frac{1}{3}\end{aligned}[/tex].

Under the ideal gas assumptions, the same ratio would apply to the volume of [tex]{\rm N_{2}}\, (g)[/tex] and [tex]{\rm H_{2}}\, (g)[/tex] in this reaction:

[tex]\begin{aligned}\frac{V({\rm N_{2}})}{V({\rm H_{2}})} = \frac{n({\rm N_{2}})}{n({\rm H_{2}})} = \frac{1}{3}\end{aligned}[/tex].

[tex]\begin{aligned}V({\rm N_{2}})= \frac{1}{3}\, V({\rm H_{2}})\end{aligned}[/tex].

Given that [tex]V({\rm H_{2}}) = 5.0\; {\rm L}[/tex]:

[tex]\begin{aligned}V({\rm N_{2}}) &= \frac{1}{3}\, V({\rm H_{2}}) \\ &= \frac{1}{3}\times 5.0\; {\rm L} \\ &\approx 1.7\; {\rm L}\end{aligned}[/tex].

(Rounded to [tex]2[/tex] significant figures.)

Given that the mixture of the three gases has a pressure of 2.6 atm, the partial pressure of O₂ is 1.924 atm

This law states that at contact temperature, the total pressure of a mixture of gases is equal to the sum of the partial pressure exerted by each gas. Mathematically, it is expressed as

Total pressure = partial pressure of A + partial pressure of B

Partial pressure of O₂ = (percentage of O₂) × total pressure

Partial pressure of O₂ = 74% × 2.6

Partial pressure of O₂ = 0.74 × 2.6

Partial pressure of O₂ = 1.924 atm

The property of mixture which describes a mixture are it can be separated by physical methods, it can appear different from different sources and it cannot be described by a chemical symbol or formula.

Mixtures are the compounds which are formed by the addition or combination of one or two elements or compounds.

As in the mixtures many states of matters are present and it will be filtered by using various physical methods, and it is not chemically shown by single chemical symbol or formula. Mixtures are also of two types:

V1= 19.229L

Explanation:

V1/T1 = k

V1/836.06=14.509/625.06

V1/836.06= 0.023

V1 = 19.229L

The temperature of CI₂ is changed from 836.06K to 625.06K. If it's new volume is 14.509L then its original volume in liters was 19.4 L.

The combined gas law is the law of of gaseous state which is made by combination of Boyle's law, Charle's law, Avogadro's law and Gay Lussac's law.

It is a mathematical expression that relates Pressure, Volume and Temperature.

(P1 × V1)÷T1 = (P2 × V2)÷T2

We can also use the following relation-

PV = nRT

According to the question, Pressure is constant and we can write the formula as-

V1÷T1 = V2÷T2

T1 = 836.06 K

T2 = 625.06 K

V1 = ?

V2 = 14.509 L

V1 = 19.4 L

Therefore, The temperature of CI₂ is changed from 836.06K to 625.06K. If it's new volume is 14.509L then its original volume in liters was 19.4 L.

Inhibition of protein synthesis is the mode of action done by most antifungal drugs.

Antifungals drugs inhibit the synthesis of ergosterol the main fungal sterol, polyenes which interact with fungal membrane sterols and 5-fluorocytosine inhibits macromolecular synthesis.

So we can conclude that inhibition of protein synthesis is the mode of action done by most antifungal drugs.

[tex]\displaystyle K_a = \frac{[\text{H$_3$O}^+][\text{F}^-]}{[\text{HF}]}[/tex]

Explanation:

Write the reaction of HF (a weak acid) with water:
[tex]\displaystyle \text{HF}_\text{(aq)} + \text{H$_2$O}_\text{($\ell$)} \rightleftharpoons \text{H$_3$O}^+_\text{(aq)} + \text{F}^-_\text{(aq)}[/tex]

Recall that the equilibrium constant expression for an equilibrium reaction is the product of the concentration of the products over the product of the concentration of the reactants raised to their respective coefficients.

The equilibrium constant expression for this equation will hence be:

[tex]\displaystyle K_a = \frac{[\text{H$_3$O}^+][\text{F}^-]}{[\text{HF}]}[/tex]

Note that pure solids and liquids are not included in the equilibrium expression.

In conclusion:

[tex]\displaystyle K_a = \frac{[\text{H$_3$O}^+][\text{F}^-]}{[\text{HF}]}[/tex]

When matter interact with EMR then spectrum is obtained. We can understand both spectra using Bohr's hydrogen spectrum. let's have a look on Bohr's hydrogen spectrum what does it say. It says when a electron gains energy it moves from one energy level to other(lower to higher) which is Absorption phenomenon. When the electrons returns from excited state to ground state they emits several spectral lines. this spectrum is called as emission spectrum. inshort the

Emission spectrum is spectrum of electromagnetic radiations that were emitted from the higher energy state(Excited state) to lower energy state(Ground state). and study of emission spectrum is known as AES (Atomic Emission spectroscopy).

When an atom or ion is subjected to EMR, it absorbs certain level of radiations, and when this absorbed energies are studied under spectroscopy they are plotted as absorption spectrum, and study of Absorption spectrum is known as AAS (Atomic Absorption spectroscopy).
