Question

Acetylene gas, C₂H₂, reacts with oxygen according to the following equation. If 1.00 mole of acetylene reacts completely with sufficient oxygen, how many moles of carbon dioxide are produced? 2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O

Answer 1

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.
