Question

Liquid octane (C8H18), a component of gasoline, reacts with gaseous oxygen to form gaseous carbon dioxide and water vapor. Write the balanced chemical reaction for this process. Express your answer as a chemical equation including phases.

Answer 1

Answer : The balanced chemical reaction will be,

`2C_8H_(18)(l)+25O_2(g)\rightarrow 16CO_2(g)+18H_2O(g)`

Explanation :

The process is a combustion reaction.

Combustion reaction : It is a type of reaction in which a hydrocarbon react with the oxygen gas to give carbon dioxide gas and water vapor as a product.

As per question, when liquid octane react with oxygen gas to give carbon dioxide gas and water vapor as a product.

Thus, the balanced chemical reaction will be :

`2C_8H_(18)(l)+25O_2(g)\rightarrow 16CO_2(g)+18H_2O(g)`
