Individual Reactions

 (g) = CH₃Hg (g) +  (g)

By formula: C₂H₆Hg (g) = CH₃Hg (g) + CH₄ (g)

 (l) + 2 (cr) = 2 (l) +  (cr)

By formula: C₂H₆Hg (l) + 2I₂ (cr) = 2CH₃I (l) + HgI₂ (cr)

 (l) + 2 (l) = 2 (g) +  (cr)

By formula: C₂H₆Hg (l) + 2Br₂ (l) = 2CH₃Br (g) + Br₂Hg (cr)

 (l) + Cl₂Hg (cr) = 2 (cr)

By formula: C₂H₆Hg (l) + Cl₂Hg (cr) = 2CH₃ClHg (cr)

 (l) +  (cr) = 2 (cr)

By formula: C₂H₆Hg (l) + Br₂Hg (cr) = 2CH₃BrHg (cr)

 (l) +  (cr) = 2 (cr)

By formula: C₂H₆Hg (l) + HgI₂ (cr) = 2CH₃HgI (cr)
