⌬ According to the Question :

Given That-

[tex] \\ \longrightarrow\sf \: Ka = {a}^{2}c[/tex]

[tex] \\ [/tex]

★Need To Find-

• Calculate Dissociation Constant Of Acid

[tex] \\ [/tex]

★Formula To Be Used-

[tex] \small\longrightarrow \sf \: \boxed{\bf\pink{a = \frac{Percent \: Dissociation}{100} }}[/tex]

[tex] \\ [/tex]

❒ Let's Find-

[tex] = \sf \: \frac{0.5}{100} \\ [/tex]

[tex] \sf➪ \: 5 × 10⁻⁴ \\ [/tex]

[tex] \sf➪ \: C = 0.02 M \\ [/tex]

[tex] \sf➪ \: 2 × 10⁻²M \\ [/tex]

[tex] \\ {\underline{\rule{160pt}{4pt}}} [/tex]

✠Hence, Kₐ

[tex] \\ [/tex]

[tex]\longmapsto \sf \: (5 \times 10⁻⁴) ^{2} \times 2 \times 10 ^{ - 2} \\ \\ \longmapsto \sf \: 25 \times 10⁻⁸ \times 2 \times {10}^{ - 2} \: \: \: \\ \\ \longmapsto \sf \: 50 \times 10 ^{ - 10} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \longmapsto \sf \: \boxed{\bf\pink{ 5 \times {10}^{ - 9} }} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]

❛❛ Therefore, The Dissociation Constant Of Acid Is = 5 × 10⁻⁹ ❜❜

[tex] \\ {\underline{\rule{300pt}{9pt}}} [/tex]

[tex]{ \underline {\large{ \sf{Solution}}}}[/tex]

The dissociation constant of acid is Given by [tex] \rm{Ka=a^2c.}[/tex]

• [tex]\rm{a=\dfrac{Percent \: Dissosiation}{100}}[/tex]

Putting Values

[tex] \dashrightarrow\rm{ = \dfrac{0.05}{100}}[/tex]

[tex] \dashrightarrow \rm{= 5 \times 10^{-4}}[/tex]

[tex]\dashrightarrow\rm{ \green{C = 0.02 M}}[/tex]

[tex] \dashrightarrow \rm{=2 \times 10^{-2} {m}}[/tex]

Hence, K =

[tex]{ \dashrightarrow{\rm{(5 \times 10^{ -4})²×2×10^{-²} }}}[/tex]

[tex] {\dashrightarrow \rm{25 × 10^{ - 8} × 2 × 10^{-2}}}[/tex]

[tex]{ \dashrightarrow\rm{=50\times 10^{-10}}}[/tex]

[tex]{ \green{ \dashrightarrow\rm{-5 × 10^{⁹}}}}[/tex]

• Therefore, The Dissociation Constant Of Acid Is = 5 × 10⁻⁹

MAKE ME BRANIEST

MAKE ME BRANIEST Explanation:

The word “one” probably shouldn’t be part of the phrase. The phrase is probably meant to be “After the heat and dust of the last month” and would mean that the conditions or activities of the past month have been unpleasant—hot and dusty. The phrase would make sense in sentences like these:

After the heat and dust of the past month, encountering yet another problem tested me beyond my limits, and I lost my temper.

After the heat and dust of the past month, taking a bath and sitting in an air conditioned room felt like heaven.
