Which of the following will have the slowest rate of diffusion at a given temperature?

marysya [2.9K]

<h3>Answer:</h3>

Chlorine gas (Cl₂)

<h3>Explanation:</h3>

According to the Graham's law of diffusion, the diffusion rate of a gas is inversely proportional to the square root of its density or molar mass.
Therefore, a lighter gas will diffuse faster at a given temperature compared to a heavy gas.
Consequently, the heavier a gas is then the denser it is and the slower it diffuses at a given temperature and vice versa.

In this case we are given gases, CI₂

, H₂,He and Ne.

We are required to identify the gas that will diffuse at the slowest rate.
In other words we are required to determine the heaviest gas.

Looking at the molar mass of the gases given;

Cl₂- 70.91 g/mol

H₂- 2.02 g/mol

He - 4.00 g/mol

Ne- 20.18 g/mol

Therefore, chlorine gas is the heaviest and thus will diffuse at the slowest rate among the choices given.

The function of a specific enzyme is most directly influenced by its

Otrada [13]

The function of a specific enzyme, a certain biological catalyst is most directly influenced by its shape and structure. The shape of the enzyme, primarily determined by the composition of amino acids that constitute or make up the primary structure of it. Will vary in terms of the interactions between these amino acids, and various parts within it. Observed in later levels of protein organization.

Metric conversions.<br> Please help ASAP.

lesya692 [45]

Answer:

14. 13.2cg = 1.32dg

15. 3.8m = 0.0038km

16. 24.8L = 24800mL

17. 0.87kL = 870L

18. 26.01cm = 0.0002601km

19. 0.001hm = 10cm

Explanation:

14. 13.2/10 = 1.32

15. 38/1000 = 0.0038

16. 24.8(1000) = 24,800

17. 0.87(1000) = 870

18. 26.01/100000 = 0.0002601

19. 0.001hm(10000) = 10

An easy way to do these by yourself is to familiarize yourself with what each prefix means. Once you do this, you can multiply the value of the prefix when converting from a smaller unit of measurement to a larger one and divide the value of the prefix when converting from a large unit of measurement to a smaller one.

What is the coordination number for each of the following complexes or compounds?

Lelu [443]

Answer:

a. 4, b. 6, c. 4, d. 2

Explanation:

The coordination number (CN) of a complex of a compound is the number of bonds that a metallic ion does with the binders, which can be equal or not.

a. The metallic ion is the iron (Fe), and it's bonded to 2 gly and 2 H2O, thus, CN = 4.

b. EDTA is a hexadentate molecule, thus, it forms 6 bonds with the metal Cr, and CN = 6.

c. The metal is Pt, which has 4 bonds with NH3, thus CN = 4.

d. The metal is Ag, which forms 2 bonds with NH3. NO3 is bonded with the structure and not with the metal. Thus, CN = 2.
