The required solution is prepared taking 0.1 mL of 10 M stock NaOH solution and placing it into a 100 mL volumetric flask. The solution is made up to 100 mL with distilled water in order to have a 100 mL solution of 10 mM NaOH solution.
The required solution is prepared by diluting a given volume of the stock solution.
Using the dilution formula: C₁V₁ = C₂V₂
Where C₁ = initial concentration of solution
V₁ = initial volume of solution
C₂ = final concentration of solution
V₂ = final volume of solution
From the given values:
C₁ = 10 M, V₁ = ?, C₂ = 10 mM = 0.01 M, V₂ = 100ml
Making V₁ subject of the formula in the dilution formula:
V₁ = C₂V₂/C₁
V₁ = 0.01 * 100 / 10
V₁ = 0.1 mL
Therefore, the volume of stock solution needed to prepare 100 mL of 10 mM NaOH solution is 0.1 mL.
0.1 mL of 10 M stock NaOH solution is taken and put into a 100 mL volumetric flask. The solution is made up to 100 mL with distilled water in order to have a 100 mL solution of 10 mM NaOH solution.

The seasonal shifts of Earth's planetary wind and moisture belts are due to changes in the latitude that receives the sun's vertical rays.
<h3>What is the latitude?</h3>
The latitude refers to the specific geographic coordinates at some point of the Earth in relation to the Equator line.
Latitude and longitude are geographic coordinates that allow to localize a specific point in the world by using the center of the Earth's planet as point of origin.
The amount of sun rays received by a given latitude largely depends on the season since the Earth's planet has a light inclination that alter this amount of radiation.
In conclusion, the seasonal shifts are due to changes in the latitude that receives the sun's vertical rays.

Answer:
OH⁻ and H₂O
Explanation:
From the equation given in question ,
NH₃ (aq) + H₂O (l) ⇌ NH₄⁺ (aq) + OH⁻ (aq)
Acids are the species which furnish hydrogen ions in the solution or is capable of forming bonds with electron pair species as they are electron deficient species.
When an acid donates a proton, it changes into a base which is known as its conjugate base.
Bases are the species which furnish hydroxide ions in the solution or is capable of forming bonds with electron deficient species as they are electron rich species. When a base accepts a proton, it changes into a acid which is known as its conjugate acid.
The acid and the base which is only differ by absence or presence of the proton are known as acid conjugate base pair.
Hence , from the equation given in the question ,
The conjugate acid - base pair is -
OH⁻ and H₂O
