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

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
