mezya [45]

Answer: Hydrogen molecules will have greatest average speed.

Explanation:

The formula for average speed is  :

\mu_{av}={\sqrt{\frac{8RT}{\pi\times M}}}

R = gas constant  

T = temperature  

M = Molecular Mass

Now putting all the values:

\frac{\nu_{H_2}}{\nu_{O_2}}=\sqrt{\frac{8RT}{\pi\times M_{H_2}}}/{\sqrt{\frac{8RT}{\pi\times M_{O_2}}}

\frac{\nu_{H_2}}{\nu_{O_2}}=\sqrt{\frac{16}{2}}

\frac{\nu_{av}_{H_2}}{\nu_{av}_{O_2}}=8

Thus average speed of hydrogen is 8 times the average speed of oxygen. Thus hydrogen molecules will have greatest average speed

A fixed amount of oxygen gas is held in a .500 L tank at a pressure of 4.39 atm. The tank is connected to an empty 1.50 L tank b
DochEvi [55]

Answer:

1.0975 atm.

Explanation:

<em>According to Boyle’s Law:</em> " At constant temperature , the  volume of a given quantity of a gas  varies inversely with its pressure".

P α 1/V.

<em>∴ P₁V₁ = P₂V₂.</em>

P₁ = 4.39 atm, V₁ = 0.5 L.

P₂ = ??? atm, V₂ = 2.0 L.

<em>∴ P₂ = P₁V₁/V₂</em> = (4.39 atm)(0.5 L) / (2.0 L) = <em>1.0975 atm.</em>
