How many grams of H20 can be found in a sample of 38.1 moles of H20 ?

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.

am i too late?

explanation:

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
