Question

Write balanced chemical reaction for the combustion of octane, c8h18..

Answer 1

The balanced chemical reaction for the combustion of octane (C8H18) is:

`\[2 \text{C}_8\text{H}_(18(l)) + 25 \text{O}_2(g) \rightarrow 16 \text{CO}_2(g) + 18 \text{H}_2\text{O}(l)\]`

Step-by-step explanation:

Octane
`(\(C_8H_(18)\))` combustion is a chemical reaction with oxygen
`(\(O_2\)),`producing carbon dioxide
`(\(CO_2\))` and water
`(\(H_2O\))` as products. The balanced equation is
`\(2C_8H_(18) + 25O_2 \rightarrow 16CO_2 + 18H_2O\).`

In this equation, the coefficients ensure that the number of each type of atom is the same on both sides of the reaction, maintaining the law of conservation of mass. The balanced reaction signifies that two moles of octane react with 25 moles of oxygen to yield 16 moles of carbon dioxide and 18 moles of water.

This reaction is essential in understanding the combustion process of hydrocarbons, crucial for applications like internal combustion engines in vehicles.

The combustion of hydrocarbons is a fundamental concept in chemistry, and understanding these reactions is crucial for various industrial and environmental applications. It provides insights into energy release, emission control, and the efficient use of fuel sources.
