- Synthesis Reaction
- Combustion Reaction
- Decomposition Reaction
- Single Replacement Reaction
A synthesis reaction is a type of reaction in which multiple reactants combine to form a single product. Synthesis reactions release energy in the form of heat and light, so they are exothermic. An example of a synthesis reaction is the formation of water from hydrogen and oxygen. Synthesis is, in essence, the reversal of a decomposition reaction.
Recognizing and understanding synthesis reactions.
Determining Products of a Synthesis Reaction
A combustion reaction (commonly known as burning) is an exothermic reaction in which something reacts with oxygen. The combustion of organic compounds usually takes the form organic compound + oxygen => water + carbon dioxide.
Recognizing and understanding combustion reactions.
A decomposition reaction is a reaction in which a single reactant produces multiple products. An example of a decomposition reaction is when water is broken down into hydrogen and oxygen. In essence, decomposition is the opposite of a synthesis reaction.
Recognizing and understanding decomposition reactions.
Single Replacement Reaction
In a single replacement reaction, a single element replaces an atom in a compound producing a new compound and a pure element. Like double replacement reactions, metals always replace metals and nonmetals always replace nonmetals in a compound.
Recognizing and understanding single replacement reactions.
This video explains Single Replacement Reactions in a very simple way. During the video, press pause to try some of the single replacement problems on your own. To solve single replacement reactions, you'll need an activity series.
