Question
Write the balanced equation for the cracking of hexane (C6H14) to produce ethene (C2H4) and butane (C4H10).
Answer
C6H14 → C2H4 + C4H10
Explanation
This question tests the student's understanding of cracking reactions, specifically how to write balanced equations. The balanced equation shows the conversion of hexane into smaller hydrocarbons, demonstrating the process of cracking.
Common mistake
Incorrect Cracking Equation
Students often write the cracking equation without balancing the number of atoms on both sides, leading to incorrect stoichiometry.
To fix this, ensure that the number of each type of atom is the same on both sides of the equation. For example, when cracking hexane (C6H14) into ethene (C2H4) and butane (C4H10), write the balanced equation: C6H14 → C2H4 + C4H10. Check that there are 6 carbons and 14 hydrogens on both sides.
