Common mistake

Common Mistake in Combustion Equations

Students often forget to balance the number of carbon, hydrogen, and oxygen atoms in the combustion equations for alcohols.

Always check that the number of atoms of each element is the same on both sides of the equation. Practice balancing equations step by step.
