Uranium isotopes have been separated by taking advantage of the different rates of diffusion of the two formsof uranium hexafluoride, one containing U-238 isotope and the other containing U-235. What are the relative rates of diffusion of these two molecules under ideal conditions ?

Assertion U-235 is unstable isotope of uranium. Unergo alpha- decay. Reason alpha- decay is observed with all radioactive isotopes having atomic number greater than 82.

Assertion. All organisms contain the same organic compounds in about the same proportions. Reason. All organisms have evolved from the first primitive cells which came into existence about 3.6 billion years ago.
