What is the molecular description of diffusion?

Chemistry

muminat3 years ago
8 0
First, we must understand what diffusion is! Diffusion is the movement of particles from a high concentration to a lower concentration, in order to reach equilibrium. Cells in particular need this to maintain homeostasis, or an internal equilibrium (stability).

Do you mean molecular size or composition, perhaps? Bigger particles are harder to move than smaller molecules. Additionally, physical constitution of a particle will affect the rate of diffusion. Think of a mouse squeezing under a door as compared to a rock, of the same size. A mouse will more easily be able to squeeze through the gap

A 5.0 L sample of gas at 300. K is heated to 600. K. What will the new volume of the gas be?
Ainat [17]

Answer:

V_2=10L

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the required new volume by using the Charles' law as a directly proportional relationship between temperature and volume:

\frac{V_2}{T_2} =\frac{V_1}{T_1}

In such a way, we solve for V2 and plug in V1, T1 and T2 to obtain:

V_2=\frac{V_1T_2}{T_1}\\\\V_2=\frac{5.0L*600K}{300K}\\\\V_2=10L

Regards!

An oxide of nitrogen contain its own volume of nitrogen
kirill115 [55]

Answer:

NO2 is the molecular formula  of nitrogen Oxide​

Explanation:

Correct question

An oxide of nitrogen contain its own volume of nitrogen

its vapour dentity is 23. Find the molecular formula

Of nitrogen Oxide

Solution

As we know

Molecular Weight  is equal to two times the  vapour density

Hence, the molecular weight of Oxide of nitrogen is 2 * 22 = 44

Molecular weight of Oxide of nitrogen  is the sum of atomic weight of nitrogen and oxygen

Molecular weight of Oxide of nitrogen = 14 + 16 *Y

14 + 16 *Y  = 46

Y = 2

Hence, the formula is NO2
