Which of the following is an example of an oxidation reaction? (2020)

Step 1: Understand what oxidation means. Oxidation is a process where a substance loses electrons.
Step 2: Look at the reaction given: C + O2 → CO2.
Step 3: Identify the elements involved. Here, we have carbon (C) and oxygen (O2).
Step 4: Determine what happens to carbon in the reaction. Carbon combines with oxygen to form carbon dioxide (CO2).
Step 5: Recognize that when carbon forms CO2, it loses electrons. This loss of electrons is what we call oxidation.
Step 6: Conclude that in this reaction, carbon is oxidized because it loses electrons to become part of CO2.
