Answer: Option (C) is the correct answer.

Explanation:

A mixture in which the components are evenly distributed or the components are present in same proportion throughout the mixture is known as a homogeneous mixture or solution.

As a result, there exists only one phase in the mixture. The components of mixture can be in solid, liquid or gaseous form.

For example, when sodium chloride (solid phase) is added in water (liquid phase) then it completely dissolve in it. Thus, there will be no boundary between the solute and solvent. Hence, it forms a homogeneous solution.

Therefore, we can conclude that a homogeneous mixture or solution consists of substances in more than one phase.

The chemical equation for the formation of ammonia is unbalanced.

ratelena [41]

Balance Chemical equation is as follow,

 3 H₂ (g) + N₂ (g) → 2 NH₃ (g)

According to balanced equation, 3 Molecules (3 moles) of Hydrogen reacts with 1 Molecule of N₂ to produce 2 moles (2 Molecules) of NH₃.

Result:
2 Molecules of Ammonia are produced by reacting 3 molecules of Hydrogen and 1 molecule of Nitrogen.

A diffusion coefficient KG was determined for the diffusion of a gas A through a stagnant film B [KG = 0.88 mol//h-ft2-atm].

Angelina_Jolie [31]

Explanation:

Transfer of mass A into stagnant film B depends on the availability of driving force.

Whereas driving force is the pressure difference at the surface of A and the bulk.

As, $N_{A} \propto (P_{A1} - P_{A2})$

$N_{A} = K_{G} \times (P_{A1} - P_{A2})$

Therefore, putting the given values into the above formula as follows.

$N_{A} = K_{G} \times (P_{A1} - P_{A2})$

= $0.88 \times (0.2 atm - 0.05 atm)$

= 0.132 $mol/h.ft^{2}$

Thus, we can conclude that the flux of A from a surface into a mixture of A and B is 0.132 $mol/h.ft^{2}$

How does a filter separate mixtures like sand and water?

Talja [164]

Answer:

Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue ) the water passes through the filter paper (it becomes the filtrate )
