Question

Methane (CH4) is the main component of marsh gas. Heating methane in the presence of sulfur produces carbon disulfide and hydrogen sulfide as the only products.

(a) Write the balanced chemical equation for the reaction of methane and sulfur.

Answer 1

CH4 + 4 S ---- CS2 + 2H2S

Answer 2

CH4 + S2   => CS2  + 2 H2S

Answer 3

CH4 + 4 S --> CS2 + 2 H2S

Answer 4

For the reaction (skeleton) CH4 + S -> CS2 + H2S is balanced as CH4 +4S -> CS2 + 2H2S
