Identify the Balanced Equation to Show the Reaction of Gaseous

question 150

Multiple Choice

Identify the balanced equation to show the reaction of gaseous ethane with gaseous oxygen to form carbon monoxide gas and water vapour.

• A) 2C₂H₆(g) + 7O₂(g) → 4CO₂(g) + 6H₂O(g)
• B) C₂H₆(g) + 5O(g) → 2CO(g) + 3H₂O(g)
• C) 2C₂H₆(g) + 5O₂(g) → 4CO(g) + 6H₂O(g)
• D) C₂H₆(g) + 7O(g) → 2CO₂(g) + 3H₂O(g)
• E) 2CH₃(g) + 5O(g) → 2CO(g) + 3H₂O(g)
