Reduction and oxidation reactions – redox reactions lost reduction oxygen atoms electrons lost gained redox gained oxidation

Are these reactions examples of oxidation or reduction?

Oxidation reactions An oxidation reaction is a reaction in which oxygen atoms are gained by a substance. _________________

Are these examples of oxidation or reduction?

Reduction reactions A reduction reaction is a reaction in which oxygen atoms are lost from a substance. _________________

Redox reactions A redox reaction, which is a common type of chemical reaction, consists of both oxidation and reduction.

Redox reactions lost oxygen atoms gained oxidation reduction redox

Redox reactions lost reduction oxygen atoms electrons lost gained redox gained oxidation

Redox reactions Carbon gains oxygen atoms in the reaction 1. What has changed in C? so it undergoes an oxidation reaction. 2. Has C gained or lost oxygen atoms? 3. Check the definition. 4. Repeat the process for iron. Iron(III) oxide loses oxygen atoms in the reaction so it undergoes a reduction reaction.

Redox reactions 1. 2. 3. 4. What has changed in C? Has C gained or lost oxygen atoms? Check the definition. Repeat the process for iron.

Redox reactions Identify which substance is going through oxidation and which is going through reduction?
