which answer best describes what is happening in the following reaction? 2c₈h₁₈ + 25o₂ → 16co₂ + 18h₂o\nthis is not a redox reaction. it is an example of combustion.\nthis is a redox reaction in which octane (c₈h₁₈) is the reducing agent.\nthis is a redox reaction in which carbon dioxide (co₂) burns due to ignition.\nthis is not a redox reaction, because a solution of carbon dioxide and water results.
Answer
Brief Explanations:
In the given reaction, octane ($C_8H_{18}$) reacts with oxygen ($O_2$) to form carbon - dioxide ($CO_2$) and water ($H_2O$). Oxidation states of elements change. Carbon in octane has an oxidation state that changes upon forming carbon - dioxide, and oxygen's oxidation state changes from 0 in $O_2$ to - 2 in $CO_2$ and $H_2O$. Octane loses electrons (is oxidized) and is the reducing agent. This is a redox reaction as well as a combustion reaction. Combustion reactions are often redox reactions.
Answer:
This is a redox reaction in which octane ($C_8H_{18}$) is the reducing agent.
