Question

One of the products of the combustion reaction below:

C5H12 + O2 → CO2 + _____ is

1. C2H5OH 3. CH4

2. H2O 4. NO

Answer 1

H₂O

Step-by-step explanation:

Chemical equation:

C₅H₁₂ + O₂ → CO₂ + H₂O

Balanced chemical equation:

C₅H₁₂ + 8O₂ → 5CO₂ + 6H₂O

The given reaction is combustion reaction. The balance equation shows that there are equal number of moles of carbon, hydrogen and oxygen on both side of equation thus it follows the law of conservation of mass.

Combustion reaction:

The reaction in which substance react with oxygen and produced carbon dioxide and water.

Mostly hydrocarbons burns in the presence of oxygen and form carbon dioxide and water.
