1. Balance the following equation Al +
HCI >
AlCl3 +
H2
How many moles of Al are needed to react with 1.6 moles of HCI?

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.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
