The highest point of a wave<span> is </span>called<span> the </span>crest<span>. ... </span>Wave<span> height is the vertical </span>distance between<span> the </span>crest<span> and trough. Wavelength is the horizontal </span>distance between waves<span> in a series. Wavelength can be measured </span>between two wave crests<span>.</span>
Molar mass:
( Br₂ ) = 159.80 g/mol
AlCl₃ = 133.34 g/mol
<span>2 AlCl</span>₃<span> + 3 Br</span>₂<span> = 2 AlBr</span>₃<span> + 3 Cl</span>₂
2 x ( 133.34) g ------------ 3 x ( 159.80) g
11.95 ------------------------ ( mass Bromine )
mass Bromine = 11.95 x 3 x 159.80 / 2 x 133.34
mass Bromine = 5728.83 / 266.68
mass Bromine = 21.48 g
hope this helps!
