Question

What are the products formed when C4H8 is burned.

• C4O2, H8O B) a salt, water
C) CO2, H2O D) O2, H2O

Answer 1

The correct answer is (C) CO2 and H2O.

When C4H8 (butene) is burned, it reacts with oxygen (O2) from the air to form carbon dioxide (CO2) and water (H2O) as products. The balanced chemical equation for this reaction is:

C4H8 + 6O2 → 4CO2 + 4H2O

Therefore, the products formed when C4H8 is burned are carbon dioxide and water.
