Answer is: concentration ammonia is higher than concentration of ammonium ion.
Chemical reaction of ammonia in water: NH₃ + H₂O → NH₄⁺ + OH⁻.
Kb(NH₃) = 1,8·10⁻⁵.
c₀(NH₃) = 0,8 mol/L.
c(NH₄⁺) = c(OH⁻) = x.
c(NH₃) = 0,8 mol/L - x.
Kb = c(NH₄⁺) · c(OH⁻) / c(NH₃).
0,000018 = x² / 0,8 mol/L - x.
solve quadratic equation: x = c(NH₄⁺) = 3,79·10⁻³ mol/L.

Answer:
Work done on the system is zero , hence no work is done since the process is <u>isochoric.</u> There is no work done if the volume remains unchanged. (Though the temperature rises, work is only accomplished when the volume of the gas changes.)
Explanation:
ISOCHORIC PROCESS - An isochoric process, also known as a constant-volume process, isovolumetric process, or isometric process, is a thermodynamic process in which the volume of the closed system undergoing the process remains constant through the process. The heating or cooling of the contents of a sealed, inelastic container is an example of an isochoric process. The thermodynamic process is the addition or removal of heat, the closed system is established by the isolation of the contents of the container, and the constant-volume condition is imposed by the container's inability to deform. It should be a quasi-static isochoric process in this case.
<u>Hence , the work done in the system is zero.</u>
The teacher prepares 2.50 liters (l) of a salt solution for a class experiment, in this quantity 2.65 quartz are present.
<h3>What is conversion factor?</h3>
Conversion factor is a quantity which will be multiplied or divide with any other measurement for the conversion of that measurement.
Given that quantity of salt solution = 2.50 L
We know that, 1 L = 1.06 qt
Here conversion factor is 1.06 qt/L as it will be multiplied on given measurement to convert into quartz as:
2.50L = 2.50L × 1.06qt/L = 2.65qt
Hence required value is 2.65qt.

Answer:
It is a reactant, so it enters the plant.
Explanation:
Hello,
Photosynthesis is the natural process occurring when plants produce sugar and oxygen by using the visible light as the catalyst to undergo the following chemical reaction:
In such a way, it is seen that the carbon dioxide has the role of reactant as it is used by the plant, that is, it enters the plant to allow the photosynthesis to be carried out.
Best regards.
