Question

Which of the following gases will have the highest velocity at a given temperature?

Answer 1

Ne

O2

He

Cl2

Answer 2

He ( it has the lowest molar mass)

rate Na / rate unknown = square root ( molar mass unknown/ molar mass Ne)
7.0 / 4.9 = square root ( x/ 20)
1.43 = square root ( x / 20)
2.04 = x / 20
x = 41 g/mol

Answer 3

lol yeah i know i found that on yahoo.... but i need to know if its right or not

Answer 4

It's correct!

Answer 5

lol how do you know?

Answer 6

Answer 7

Since you're talking about more than one molecule here, in a given chamber, you would be using an average, and thus, the one with the lightest mass would travel fastest. A bean would jump faster than a rock, if you kicked a table from under.

Answer 8

Kinetic Energy = mass \(\times\) velotcity

Answer 9

lol okay? thanks c:
