Question

Rank the following gases according to increasing average molecular speed at 150 oC: H2, CH4, N2, I2, O2, C3H8. In one brief sentence, explain why you ranked the gases in the order you did.

Answer 1

Answer:
`I_(2)`,
`C_(3) H_(8)`,
`O_(2)`,
`N_(2)`,
`CH_(4)`,
`H_(2)`

Step-by-step explanation:

The smaller the molecular mass, the higher the molecular speed.
`I_(2)` has largest molecular mass, and Hydrogen has the smallest molecular mass.
