An isotope of Luckycharmium has a half-life of 120 days. How many days will have passed when 50% of a Luckycharmium sample remains?

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

the answer is na (sodium)

12 is it do you think so
