If 2.0 moles of magnesium hydroxide are present, how many moles
of phosphoric acid, would be required for the reaction?

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.

i wish i could but this one is weird give me abc and i can solve it.

they are all solids.

0.88m hope i am correct : )
