CALCULATE THE RMM OF , CA(OH)2, AL2SO4.

The RMM of Ca (OH)2 is

40+ (16+1)2

40+(17)2

40+34

74

The RMM of Al2SO4 is

(27×2)+32+(16×4)

54+32+64

=150

Explanation:

Note that the RAM of:

Ca=40

O=16

H=1

Al=27

S=32

yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes

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.
