Classifying Chemical Reactions

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat. It typically produces carbon dioxide and water as products.

Front

What are the products of a combustion reaction involving hydrocarbons?

Back

The products of a combustion reaction involving hydrocarbons are typically carbon dioxide (CO2) and water (H2O).

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, resulting in a new element and a new compound.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product.

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.

Front

What is the general form of a synthesis reaction?

Back

The general form of a synthesis reaction is A + B → AB, where A and B are reactants that combine to form the product AB.

Front

What is the general form of a decomposition reaction?

Back

The general form of a decomposition reaction is AB → A + B, where AB is the compound that breaks down into its components A and B.

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, the anions and cations of two different compounds exchange places.

Front

What is an example of a combustion reaction?

Back

An example of a combustion reaction is the burning of propane: C3H8 + 5O2 → 3CO2 + 4H2O.

Front

What type of reaction is represented by the equation Cl2 + 2KI → I2 + 2KCl?

Back

This reaction is a single replacement reaction.
