Ethane (C2H6) is one of many compounds that burns in oxygen to form carbon dioxide and water, as represented by the equation.

2C2H6 + 7O2 → 4CO2 + 6H2O

Which substance is a product in this reaction?

carbon (C)

oxygen (O2)

water (H2O)

ethane (C2H6)

Water (H2O)

Step-by-step explanation:

When hydrocarbons undergo combustion reactions (I. e reactions with oxygen) carbon (iv) oxide and water are usually produced.

In this case, the only difference is the numbe of moles between the product and reactant

Equation of reaction;

2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O

Reactants:

1. Ethane = C₂H₆

2. Oxygen = O₂

Product:

1. Carbon (iv) oxide = CO₂

2. Water = H₂O
