Step 1: Write the Unbalanced Equation<\/h3>\n\n\n\n
C6H8+O2\u2192CO2+H2OC_6H_8 + O_2 \\rightarrow CO_2 + H_2O<\/p>\n\n\n\n
Step 2: Balance Carbon (C) Atoms<\/h3>\n\n\n\n
There are six carbon atoms in C\u2086H\u2088, so we need six CO\u2082 molecules:<\/p>\n\n\n\n
C6H8+O2\u21926CO2+H2OC_6H_8 + O_2 \\rightarrow 6CO_2 + H_2O<\/p>\n\n\n\n
Step 3: Balance Hydrogen (H) Atoms<\/h3>\n\n\n\n
There are eight hydrogen atoms in C\u2086H\u2088, so we need four H\u2082O molecules:<\/p>\n\n\n\n
C6H8+O2\u21926CO2+4H2OC_6H_8 + O_2 \\rightarrow 6CO_2 + 4H_2O<\/p>\n\n\n\n
Step 4: Balance Oxygen (O) Atoms<\/h3>\n\n\n\n
On the right side, we have:<\/p>\n\n\n\n
- \n
- 6 CO\u2082 molecules \u2192 6 \u00d7 2 = 12 oxygen atoms<\/li>\n\n\n\n
- 4 H\u2082O molecules \u2192 4 \u00d7 1 = 4 oxygen atoms<\/li>\n<\/ul>\n\n\n\n
Total = 16 oxygen atoms. So we need 8 O\u2082 molecules:<\/p>\n\n\n\n
C6H8+8O2\u21926CO2+4H2OC_6H_8 + 8O_2 \\rightarrow 6CO_2 + 4H_2O<\/p>\n\n\n\n
Explanation:<\/h3>\n\n\n\n
Combustion reactions involve oxygen reacting with a hydrocarbon to produce carbon dioxide and water. Hex-1-yne (C\u2086H\u2088) is an alkyne with a triple bond. When it combusts, the carbon atoms form carbon dioxide (CO\u2082), and hydrogen atoms form water (H\u2082O). The key principle of balancing is ensuring that the number of atoms of each element is equal on both sides of the equation. Oxygen is adjusted last since it is present in multiple compounds. Proper balancing ensures the reaction follows the conservation of mass.<\/p>\n\n\n\n
