Types of Chemical Reactions

Front

What are the two main types of chemical reactions?

Back

Synthesis and decomposition.

Front

Define a synthesis reaction.

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single 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 characterizes a combustion reaction?

Back

A combustion reaction involves a substance reacting with oxygen, producing heat and light, typically resulting in carbon dioxide and water.

Front

What is a single displacement reaction?

Back

A single displacement reaction is a type of reaction where one element replaces another in a compound.

Front

Define a double displacement reaction.

Back

A double displacement reaction is a type of reaction where two compounds exchange ions or bonds to form two new compounds.

Front

Example of a synthesis reaction: 2Mg + O2 -> ?

Back

2MgO (Magnesium oxide) is formed.

Front

Example of a decomposition reaction: 2H2O -> ?

Back

2H2 + O2 (Hydrogen and oxygen gases) are produced.

Front

What is the general form of a combustion reaction?

Back

A hydrocarbon reacts with oxygen to produce carbon dioxide and water.

Front

Identify the products of the combustion of methane: CH4 + 2O2 -> ?

Back

CO2 + 2H2O (Carbon dioxide and water) are produced.
