what is the difference between coal and petroleum ?
?
According to this equation,?72g of pentane requires 256g (8x32) of oxygen for complete combustion, producing 220g (5x44) carbon dioxide and 108g (6x18) of water. However, if the amount of oxygen available is less than that required it will result in incomplete combustion as evident form the following reaction:
This equation shows that incomplete combustion of pentane occurs when 144g (2x72) of pentane is burnt with 352g (11x32) of oxygen forming 280g (10x28) of carbon monoxide and 216g (12x18) of water."
