Ethane,C₂H₆,burns to give carbon dioxide and water.What is the coefficient of oxygen in the balanced equation for the reaction? __C₂H₆(g)+ __O₂(g)  __CO₂(g)+ __H₂O(g)

Quizplus · Accepted Answer

To balance the equation, we need five coefficients of O₂ to balance the carbons and twelves coefficients of O₂ to balance the hydrogens. Therefore, the coefficient of O₂ is 7. So, the balanced equation is:
C₂H₆(g) + 7O₂(g) → 2CO₂(g) + 3H₂O(g)
