Given :
Temperature, T = 55° C = ( 55 + 273 ) K = 328 K .
Volume of container, V = 28.9 dm³ = 0.0289 m³ .
Pressure, P = 144 kPa = 144000 Pa .
To Find :
Number of moles of nitrogen gas.
Solution :
We know, by ideal gas equation :
PV = nRT ( R ( universal gas constant ) = 8.31 J K⁻¹ mol⁻¹ .
Therefore, number of moles of nitrogen gas is 1.53 moles.
Explanation:
The given reaction will be as follows.
............. (1)
=
Reaction for the complex formation is as follows.
........... (2)
=
When we add both equations (1) and (2) then the resultant equation is as follows.
............. (3)
Therefore, equilibrium constant will be as follows.
K =
=
=
Since, we need 0.010 mol of AgCl to be soluble in 1 liter of solution after after addition of for complexation. This means we have to set
=
=
= 0.010 M
For the net reaction,
Initial : 0.010 x 0 0
Change : -0.010 -0.020 +0.010 +0.010
Equilibrium : 0 x - 0.020 0.010 0.010
Hence, the equilibrium constant expression for this is as follows.
K =
=
x = 0.0945 mol
or, x = 0.095 mol (approx)
Thus, we can conclude that the number of moles of needed to be added is 0.095 mol.
Answer:
yes it rotates on its own axis
Explanation:
rotation is the movement/spinning of the earth on its own axis
revolution is the movement of the earth around the sun
Answer: Chromatography
Explanation:
Chromatography is the technique for qualitative or quantitative separation of the components of mixtures in a solution
It uses TWO phases: MOBILE phase (gas or liquid), and a STATIONARY phase (liquid or solid).
You will observe differences in the the rates of migration of the RED and BLUE compounds between the two phases during separation.
