Write equations for combustion of alcohols.

In the subtopic Alcohol production and reactions, this AQA A-Level Chemistry 7405 learning objective focuses on write equations for combustion of alcohols. It belongs to Alcohols, so revision should stay anchored to this exact subtopic rather than drifting into a generic GCSE-level chemistry summary. Approved keywords to use include alcohol, combustion. Ethanol combustion equation. means the balanced chemical equation for the combustion of ethanol (C2H5OH) is C2H5OH + 3O2 → 2CO2 + 3H2O Avoid the mistake of students often forget to balance the combustion equation for alcohols, leading to incorrect stoichiometry; instead, to write the balanced equation for the combustion of ethanol (C2H5OH), use the formula: C2H5OH + O2 → CO2 + H2O. First, balance the carbon atoms: 2 CO2. Then, balance the hydrogen atoms: 3 H2O. Finally, balance the oxygen atoms: C2H5OH + 3 O2 → 2 CO2 + 3 H2O. The final balanced equation is C2H5OH + 3 O2 → 2 CO2 + 3 H2O For exam answers, remember to balance the combustion equations for alcohols by ensuring the number of atoms on both sides is equal
