Final answer:
When 1.00 mole of acetylene reacts completely with sufficient oxygen, 2.00 moles of carbon dioxide are produced.
Step-by-step explanation:
In order to determine how many moles of carbon dioxide are produced when 1.00 mole of acetylene reacts completely with oxygen, we need to examine the balanced chemical equation:
2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O
From the equation, we can see that for every 2 moles of acetylene, 4 moles of carbon dioxide are produced. Therefore, if 1.00 mole of acetylene reacts completely, we can set up a proportion:
(1.00 mole C₂H₂)/(2 moles C₂H₂) = (x moles CO₂)/(4 moles CO₂)
Solving for x, we find that x = 2.00 moles CO₂. So, when 1.00 mole of acetylene reacts completely with sufficient oxygen, 2.00 moles of carbon dioxide are produced.
