I believe the correct answer from the choices listed above is the last option. You can separate the mixture of <span> iron beads and iron filings by using a screen distillation. Since they surely have different sizes so you can easily separate by filtration. Hope this answers the question.</span>
Answer:
We get ammonia because the forward and reverse reactions are happening at the same rates.
If 3 mol of
H
2
is mixed in a sealed vessel with 1 mol
N
2
under suitable conditions then they will react to form ammonia
N
H
3
:
N
2
+
3
H
2
→
2
N
H
3
At the start of the reaction the concentration of the
N
2
and
H
2
are high. As soon as some
N
H
3
is formed the reverse reaction will start to occur:
2
N
H
3
→
N
2
+
3
H
2
The rate of the reaction depends on concentration so the forward reaction will be fast at first when the concentration of the reactants is high. It will slow down as their concentration decreases.
By the same reasoning the reverse reaction will be slow at first then increase. These two processes continue until a point is reached when the rates of the forward and reverse reactions are equal.
We now state that the reaction has reached equilibrium which we show by:
N
2
+
3
H
2
⇌
2
N
H
3
It is described as "dynamic" because the forward and reverse reactions are happening at the same time although the concentrations of all the species remain constant.
So although
N
H
3
is constantly breaking down, more is being formed at a constant rate.
In the Haber Process the system is actually not allowed to completely reach equilibrium as the process is continuous, as described in Mukhtar's answer.
Explanation:
Equilibrium is a state of balance or a stable situation where the opposing forces cancel each other out and where no changes are occurring.
<h3>How to explain the equilibrium?</h3>
Your information is incomplete. Therefore, an overview will be given. In a chemical reaction, chemical equilibrium is a state where the reactants and products are present in concentrations that have no further tendency to change with time.
In terms of volume changes within a system at equilibrium, the following applies:
- When there is a decrease in volume, then the equilibrium will shift to favor the direction that produces fewer moles of gas.
- When there is an increase in volume, then the equilibrium will shift to favor the direction that produces more moles of gas.
In conclusion, if you increase the pressure of a system at equilibrium, the stress will be reduced by reaction that favors the side with the fewest moles of gas.

Answer:
potassium hydrogen phthalate KHP MOLAR MASS = 204.233 glmol
to get 1000 ml
Molar concentration = Mass concentration/Molar Mass
mass concentration = molar concentration x molar mass
mass concentration=0.1 M,
molar mass= 204.233 g/mol
so to get 1L
mass conc = 204.233 x 0.1
= 20.4233g for 1L or 1000 ml
to get 6.00 ml
if 20.4233g is for 1000ml
then to 6.00 ml
= 20.4233 x 6 / 1000
= 0.123g for 6.00 ml
according to the equation below
NaOH(aq) + KHC8H4O4(aq) --> KNaC8H4O4(aq) + H2O(l)
number of moles of NaOH is equal to that of KHP
so the same amount will be needed too, which is
= 0.123g
