It is a <u>mixture</u> of minerals mainly of corps that crystalizes of magma below earths surface.
Answer:
By Filtration using Filter Paper
Explanation:
Aluminium Powder is made from Aluminium with the help of mechanical means. This powder is mainly used in paints, cosmetics, fingerprint powders, thermite, rocket fuels e.t.c.
Also, Aluminium Powder is insoluble in water and organic solvents. Therefore, when mixed in Ethanol it will form a suspension. The Aluminium Powder can therefore be easily separated by simple Filtration using Filter paper.
The number of chlorine atoms needed would simply be the
ratio of distance and diameter. But first convert 200 pm to mm:
<span>200 pm = 2 E-7 mm </span>
So the number of chlorine atoms needed is:
<span>1.0 mm / (2 E-7 mm) = 5,000,000 Chlorine atoms = 5 E6
atoms</span>
