In redox reactions, electrons are transferred from the metal to the non-metal. If a species loses electrons it is oxidized; whereas, if a species gains electrons it is said to be reduced. An easy way to remember the difference between oxidation and reduction is OIL RIG. OIL RIG stands for Oxidation Is Loss and Reduction Is Gain, applying to the transfer of electrons that takes place during these reactions. The species that is oxidized in a redox reaction is also called the reducing agent. Similarly, the specie that is reduced in a redox reaction is also called the oxidizing agent.
Single-replacement
In a single-replacement reaction, the metals in the reactants change places. These reactions are based on reactivity series which show metals from most reactive to least reactive.
Synthesis
A synthesis reaction occurs when two or more reactants form one product.
Decomposition
Decomposition is a reaction in which one reactant produces two or more products.
Combustion
When a hydrocarbon reacts with oxygen in order to always produce carbon dioxide and water, it is a combustion reaction.
I found This to be helpful in practicing redox reactions
Some practice for Classifying reactions was helpful as well
These Practice Redox problems were beneficial in understanding this concept as well
Erin, this post was very helpful when it came time for the test! I made a post very similar to this, but your post included several great links that mine didn't, so it helped me understand the different types of reactions even more. The fact that you included links to practice problems and not just to pages of information made this post very beneficial in reviewing for the test. :)
