How many moles of hydrogen gas can be produced if 0.57 moles of hydrochloric acid, HC1, reacts with excess solid zinc according to the following chemical equation? 2 HC1 + Zn → H2 + ZnCl2

98

Explanation:

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.
