Question

Complete Balanced Equation for Combustion of Ethane Gas:

a) C₂H₆ + 3O₂ → 2CO₂ + 3H₂O (g)
b) C₂H₆ + 2O₂ → CO₂ + H₂O (l)
c) 2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O (g)
d) C₂H₆ + 5O₂ → 2CO₂ + 3H₂O (l)
e) C₂H₆ + 7O₂ → 4CO₂ + 6H₂O (l)

Answer 1

The correct balanced equation for the combustion of ethane gas is 2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O (g).

Step-by-step explanation:

The correct answer is option c) 2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O (g).

To balance the equation, we need to ensure that the number of atoms on both sides of the equation is equal. In this case, we have 4 carbon atoms and 12 hydrogen atoms on the left side, and 4 carbon atoms and 12 hydrogen atoms on the right side. Thus, the equation is balanced.

The state symbols (g) indicate that carbon dioxide and water are in the gas state.
