Question

2. When a fuel undergoes complete combustion it produces _________

Answer 1

Answer:

When a fuel undergoes complete combustion it produces carbon dioxide and water.

Answer 2

When a fuel undergoes complete combustion it produces carbon dioxide (CO2) and water (H2O).

Explanation:

• When there is a sufficient quantity of air, complete combustion occurs.
• In an exothermic reaction, carbon and hydrogen atoms in hydrocarbon fuel react with oxygen to form carbon dioxide and water.
• Combustion is frequently a complex series of fundamental radical reactions.
• Solid fuels, such as wood and coal, undergo endothermic pyrolysis to form gaseous fuels, which are subsequently burned to provide the heat needed to make more.
• Combustion is frequently hot enough to create incandescent light in the form of glowing or a flame.
• The combustion of hydrogen and oxygen into water vapour, which is often used to power rocket engines, is a basic example.
