iron Presence of trace elements, irradiation and iron impurities give the gem amethyst its purplish color!
CH₄(g) + 3 Cl₂(g) → CHCl₃(g) + 3 HCl(g)
From the equation we notice that 1 mole of methane produces 1 mole of chloroform:
16 g Methane → 119.38 g Chloroform
? g Methane → 37.5 g Chloroform
by cross multiplication:
= (16 * 37.5) / 119.38 = 5.0 g methane
(C) Electron cloud
the electron cloud is formed by all the electrons in the atom
