Atomic mass Kr = 83.8 g/mole
Atomic mass Ar = 39.948 g/mole
So the ratio of the effusion rates = SQRT(83.8/39.948) = 1.45. Argon moves 45% faster than krypton!
Hope that helped!
Answer:
1. Feature
2. Trait
Explanation:
I don't know how to explain why it's a feature, but number 2 is a trait because it makes you "you" (like blue eyes are different)
I think it might be eating
The correct answer for this would be silicon dioxide.
Because it looses it's science-street-cred if it can't be replicated.

If you can replicate an experiment you can prove that the results are not just a stroke of luck or happening by chance, but instead that the variables are causing the results and they will always as long as the factors of the experiment remain the same. That is the definition of a <em>scientific</em> experiment.
