Worked Solution & Example Answer:Butan-1-ol burns in oxygen according to the following equation - HSC - SSCE Chemistry - Question 4 - 2013 - Paper 1
Step 1
Calculate moles of carbon dioxide for 2 moles of butan-1-ol
Answer
From the balanced equation, 1 mole of butan-1-ol produces 4 moles of carbon dioxide. Therefore, if 2 moles of butan-1-ol are burned, the number of moles of carbon dioxide produced can be calculated as follows:
total ext{ moles of } CO₂ = 2 ext{ moles of butan-1-ol} imes 4 rac{ ext{moles of } CO₂}{ ext{mole of butan-1-ol}} = 8 ext{ moles of } CO₂.
The answer is (C) 8.
