Write and balance the equation for the complete combustion of ethane C2H6. Incomplete combustion occurs when the supply of air or oxygen is poor. C 2 H 6 + O 2 → CO + H 2 O. Incomplete Combustion •Incomplete combustion is also a reaction between oxygen and fuel but the products are carbon monoxide, water and carbon. Problems with incomplete combustion Acetylene (aka ethyne, C2H2) reacts with oxygen (O2) to make carbon dioxide (CO2) and water (H2O). In this technique, an aqueous solution of an acetate salt is electrolysed. 2CH4 + 3O2 --> 2CO2 + 4H2O + energy Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide. ethane + oxygen carbon dioxide + water + energy 2 C 2 H 6 (g) + 7 O 2 (g) 4 CO 2 (g) + 6 H 2 O (l) The reaction is exothermic (it gives out heat ). Eg: 4CH4 + 5O2 2CO + 8H2O + 2C •Incomplete combustion occurs when a combustion reaction occurs without a sufficient supply of oxygen. At the anode, acetate is oxidized to produce carbon dioxide and methyl radicals, and the highly reactive methyl radicals combine to produce ethane: Ethane can be viewed as two methyl groups joined, that is, a dimer of methyl groups. In the laboratory, ethane may be conveniently synthesised by Kolbe electrolysis. When this equation is balanced, you get: 2C 2 H 6 + 5O 2 → 4CO + 6H 2 O. ethane + oxygen → carbon monoxide + water. Combustion of Ethane: 2C2H6+7O2-->4CO2+6H2O Combustion of Ethanol: C2H5OH+3O2-->2CO2+3H2O Chemical equation for the incomplete combustion of methane gas? pha symbola and ene changes are optional .
