Which step do you use first to calculate the number of grams of FeCl2 produced when starting with 30.3 g of Fe in this reaction?

I dont care I want pionts

answer; i believe that the correct answer is (a); a large rock being weathered by wind and rain;

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.
