We are being asked to identify the reducing agent in a reaction of magnesium with oxygen
To do so, we need to identify the change in oxidation state for each element in the reaction.
Recall the mnemonic for redox reactions:
Loss Electrons →Oxidation →Reducing Agent
Gain Electrons →Reduction →Oxidizing Agent
This means the element that loses electrons/oxidized is the reducing agent.
We will do the following steps:
Step 1: Write the overall balanced reaction
Step 2: Determine the oxidation state of reactants and products
Step 3: Determine the change in oxidation state
Explain how to Identify the reducing agent in a reaction of magnesium with oxygen.
