Answer» `2CH_(4)+O_(2)overset(Cu//523 K//100 "ATM")rarr 2CH_(3)OH` `CH_(4)+O_(2)overset(Mo_(2)O_(3)) rarr HCHO + H_(2)O` `CH_(4) + O_(2)rarr C(s) + 2H_(2)O (l)` `CH_(2) + 2O_(2) rarr CO_(2)(g) + 2H_(2)O(l)` SOLUTION :During INCOMPLETE combustion carbon black is formed. It TAKES place when there is insufficient supply of air or oxygen. `CH_(4)+O_(2)rarr C_((s)) + 2H_(2)O_((l))`
