Chemistry
1 answer:
spin [16.1K]3 years ago
7 0

<u>Ans :</u>4.5 * 10²³ molecules

<u>Given:</u>

Moles of CH4 = 0.75

<u>To determine;</u>

The number of molecules of CH4 in 0.75 moles

<u>Explanation:</u>

1 mole of CH4 contains Avogadro's number i.e. 6.023*10²³ molecules

Therefore, 0.75 moles would correspond to :

= 0.75 moles * 6.023*10²³ molecules/1 mole

= 4.5 * 10²³ molecules

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 energy from Earth’s interior affect surface changes?
quester [9]

Answer:

Energy produced deep inside Earth heats rock in the mantle. ... As it becomes less dense, the heated rock rises toward Earth's surface. The cooler, denser rock surrounding the heated rock sinks, as Figure 5 shows. In this way, heat inside Earth moves toward the cooler crust.
