Question

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)

Answer 1

Answer:

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

Answer 2

Answer:

H20
