In this case, the hydrocarbon is hexane, which has the chemical formula C\u2086H\u2081\u2084. Hexane is a liquid alkane consisting of six carbon atoms and fourteen hydrogen atoms. The goal of complete combustion is to ensure all carbon becomes carbon dioxide and all hydrogen becomes water.<\/p>\n\n\n\n<p>To balance the equation, begin by writing the unbalanced form:<br>C\u2086H\u2081\u2084 + O\u2082 \u2192 CO\u2082 + H\u2082O<\/p>\n\n\n\n<p>Start with carbon atoms. Hexane has 6 carbon atoms, so the equation must produce 6 CO\u2082 molecules:<br>C\u2086H\u2081\u2084 + O\u2082 \u2192 6 CO\u2082 + H\u2082O<\/p>\n\n\n\n<p>Next, balance the hydrogen atoms. Hexane has 14 hydrogen atoms, so the equation must produce 7 H\u2082O molecules:<br>C\u2086H\u2081\u2084 + O\u2082 \u2192 6 CO\u2082 + 7 H\u2082O<\/p>\n\n\n\n<p>Now count the total oxygen atoms on the right side. There are 6 CO\u2082 (6\u00d72 = 12 oxygen atoms) and 7 H\u2082O (7\u00d71 = 7 oxygen atoms), giving a total of 19 oxygen atoms. Since each O\u2082 molecule contains 2 oxygen atoms, 19 \u00f7 2 = 9.5 O\u2082 molecules are required.<\/p>\n\n\n\n<p>To eliminate the fraction, multiply the entire equation by 2:<br>2 C\u2086H\u2081\u2084 + 19 O\u2082 \u2192 12 CO\u2082 + 14 H\u2082O<\/p>\n\n\n\n<p>This is now the balanced equation for the complete combustion of liquid hexane. This reaction is exothermic, releasing a large amount of heat, which makes hexane a useful fuel. Complete combustion requires sufficient oxygen; otherwise, incomplete combustion occurs, producing carbon monoxide or soot, which are hazardous byproducts.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-892.jpeg\" alt=\"\" class=\"wp-image-37447\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-892.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-892-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-892-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Write the balanced chemical equation for the complete combustion of hexane (l).
