In the case of <strong>hexane (C\u2086H\u2081\u2084)<\/strong>, it is a hydrocarbon composed of 6 carbon atoms and 14 hydrogen atoms. During complete combustion, each carbon atom forms carbon dioxide (CO\u2082), and each pair of hydrogen atoms forms one water molecule (H\u2082O).<\/p>\n\n\n\n<p>To write a balanced combustion reaction for hexane:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Start with the unbalanced formula:<\/strong><br>C\u2086H\u2081\u2084 + O\u2082 \u2192 CO\u2082 + H\u2082O<\/li>\n\n\n\n<li><strong>Balance carbon atoms:<\/strong><br>Hexane has 6 carbon atoms, so place a coefficient of 6 in front of CO\u2082:<br>C\u2086H\u2081\u2084 + O\u2082 \u2192 <strong>6 CO\u2082<\/strong> + H\u2082O<\/li>\n\n\n\n<li><strong>Balance hydrogen atoms:<\/strong><br>Hexane has 14 hydrogen atoms. Each water molecule has 2 hydrogen atoms, so divide 14 by 2 to get 7:<br>C\u2086H\u2081\u2084 + O\u2082 \u2192 6 CO\u2082 + <strong>7 H\u2082O<\/strong><\/li>\n\n\n\n<li><strong>Balance oxygen atoms:<\/strong><br>There are now a total of (6 \u00d7 2) = 12 oxygen atoms in CO\u2082 and (7 \u00d7 1) = 7 oxygen atoms in H\u2082O. That adds up to 19 oxygen atoms. Since each O\u2082 molecule has 2 oxygen atoms, divide 19 by 2:<br>C\u2086H\u2081\u2084 + <strong>19\/2 O\u2082<\/strong> \u2192 6 CO\u2082 + 7 H\u2082O<\/li>\n\n\n\n<li><strong>Clear the fraction by multiplying the entire equation by 2:<\/strong><br><strong>2 C\u2086H\u2081\u2084 + 19 O\u2082 \u2192 12 CO\u2082 + 14 H\u2082O<\/strong><\/li>\n<\/ol>\n\n\n\n<p>This final balanced equation shows that two molecules of hexane require nineteen molecules of oxygen to fully combust, producing twelve molecules of carbon dioxide and fourteen molecules of water.
