Answer:
Two moles of carbon dioxide were produced from this reaction.
Explanation:
2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O
All hydrocarbons burn in excess air or oxygen to give carbondioxie and water.
The general balanced equation is given by:
Cₓ Hₐ + (x+a/4)O₂ → xCO₂ + (a/2) H₂O
If given 1 mole of C₂H₂,
We know that x = 2
a = 2
For (x+a/4)O₂, we would have:
(2+2/4) = 5/2 O₂
For xCO₂, we would have 2CO₂
For (a/2) H₂O, we would have:
(a/2) H₂O = (2/2)H₂O = H₂O
Therefore, for 1mole of C₂H₂, the complete equation is written as
C₂H₂ + 5/2O₂ → 2CO₂ + H₂O
We can conclude that,
5/2 mole of O₂ would be used
2 mole of CO₂ would be produced
1 mole of H₂O would be produced
