Types of Chemical Reactions

Front

What are the four main types of chemical reactions?

Back

1. Synthesis (Combination) Reaction 2. Decomposition Reaction 3. Single Replacement Reaction 4. Double Replacement Reaction

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. Example: A + B -> AB.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products. Example: AB -> A + B.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound. Example: A + BC -> AC + B.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where the anions and cations of two different compounds exchange places, forming two new compounds. Example: AB + CD -> AD + CB.

Front

What is a combustion reaction?

Back

A combustion reaction is a type of chemical reaction that occurs when a substance reacts with oxygen, producing energy in the form of heat and light. Typically involves hydrocarbons reacting with oxygen to produce carbon dioxide and water.

Front

What is the general equation for a combustion reaction involving a hydrocarbon?

Back

C_xH_y + O_2 -> CO_2 + H_2O.

Front

What is the role of oxygen in combustion reactions?

Back

Oxygen acts as a reactant that combines with the hydrocarbon to produce carbon dioxide and water, releasing energy.

Front

What is the difference between a single replacement and a double replacement reaction?

Back

In a single replacement reaction, one element replaces another in a compound, while in a double replacement reaction, two compounds exchange components.

Front

What is an example of a double replacement reaction?

Back

An example of a double replacement reaction is: NaCl + AgNO3 -> NaNO3 + AgCl.
