What Are Five Types Of Chemical Reactions – This is the second part of the Chemical Reactions posters, this time featuring condensation, hydrolysis, displacement, oxidation and reduction reactions. Click on the image above to enlarge and read the text, or, as before, I’ve included the text in the post below. Easy-to-print versions are again available for download at the bottom of the page.
A condensation reaction is a reaction in which two molecules combine to form a larger molecule, with the loss of a small molecule. The small molecule that is lost is usually water, but not always. It can be considered an alternative to hydrolysis reactions, and is an important reaction in the manufacture of many polymers.

What Are Five Types Of Chemical Reactions
A hydrolysis reaction involves breaking chemical bonds by adding water to a substance. In some cases, this addition can split the substance and the water molecule into two parts. There are three main types of hydrolysis: salt, acid, and base. Dissolving sulfuric acid in water is a simple example of hydrolysis.
Types Of Chemical Reactions
A displacement reaction is when an element or ion moves out of one compound and into another. It usually occurs if the element moving into the compound is more reactive than the element it displaces. Double displacement reactions also occur, where anions and cations of two different molecules exchange places, forming two different compounds.
Oxidation reactions are sometimes defined as reactions in which other elements ‘move’, or form bonds with, oxygen atoms. More generally, they can be defined as reactions in which atoms lose electrons. Oxidation does not occur without an accompanying reduction reaction – these reactions are called redox reactions.
Reduction reactions are sometimes defined as chemical reactions in which other elements ‘lose’ oxygen atoms. More generally, they can be defined as reactions in which atoms gain electrons. Reduction does not occur without an accompanying oxidation reaction – these reactions are called redox reactions.

What is a chemical change, and what is a physical change? A chemical reaction occurs when compounds or substances are chemically changed to form different compounds or substances. Chemical equations express chemical reactions in terms of symbols and chemical formulas of the compounds involved in reactions. Let’s look at some examples of chemical change, and examples of chemical reactions.
In a physical change, the shape of a compound may change, but its chemical identity will not. For example, freezing or boiling of water is a physical change. Once melted or boiled, the water may be in a different form (solid ice or gaseous water vapor), but it is still water, H
A chemical change occurs when the chemical identity of a substance changes. An example of this is rust. When an iron nail comes into contact with water and then exposed to air, it rusts, forming a brown-red substance. This process changes the chemical composition of the original substance.
Although some physical changes are easily reversible, such as the refreezing of melted ice, reversing a chemical change requires another chemical reaction.
Balancing Chemical Equations
Based on its definition, a chemical reaction occurs when a substance undergoes a chemical change. So how can we tell if a chemical change has occurred?
If a reaction emits heat or light, this is a sign that energy has been released from the reaction. One example of this is a fire or spark, which is evidence of burning. Because many physical changes also involve heat or light, this is not concrete, definitive evidence of a reaction. But it is a strong argument that one happened.
When substances react and bubbles or steam appear, this is a sign that a chemical reaction is taking place. An example of this is when baking soda and vinegar react violently to produce carbon dioxide gas in the famous volcano experiment.
A precipitate is a solid product that forms as a result of a chemical reaction between liquid reactants. An example of a precipitate is yellow cadmium sulphide, which is produced when water solutions of ammonium sulphide and cadmium nitrate are combined.
Different Types Of Chemical Reactions
The most definitive way to confirm a chemical reaction is to analyze the chemical composition of the reactants and products.

Keep in mind, there are different names for the types of reactions. The four main types of chemical reactions are:
There are many other types of reactions, however. This table summarizes some key points of the main types of chemical reactions:
In a synthesis, direct combination, or composition reaction, two (or more) reactants are combined to form a more complex product. The general form of the reaction is:
Single Replacement Reaction Definition And Examples
A compound breaks or decomposes into smaller pieces in a chemical or analytical decomposition reaction. The general form of the reaction is:
A single replacement, single displacement, or substitution reaction is a reaction in which one element is displaced from a reactant to form a compound with another element. The reaction has the general form:
An example of a single replacement reaction is when zinc combines with hydrochloric acid to form zinc chloride and
