Question

During combustion, what combines with the carbon in the coal? a) Oxygen b) Nitrogen c) Hydrogen d) Helium

Answer 1

During combustion, carbon in coal combines with oxygen (Option A).

Step-by-step explanation:

Combustion is a chemical process involving the reaction of a substance with oxygen to produce heat and light. In the context of coal combustion, the primary component that combines with carbon is oxygen. The balanced chemical equation for the combustion of carbon (in coal) can be represented as:

C + O2 -> CO2

This equation indicates that carbon (C) reacts with oxygen (O2) to form carbon dioxide (CO2). The combustion of coal is an oxidation reaction where carbon undergoes a reaction with oxygen to produce carbon dioxide, releasing energy in the form of heat.

Option A is the answer.
