Types of Chemical Reactions

Front

What is a chemical reaction?

Back

A process that involves the rearrangement of the molecular or ionic structure of a substance.

Front

What are the main types of chemical reactions?

Back

Synthesis, Decomposition, Single Replacement, Double Replacement, and Combustion.

Front

Define Synthesis Reaction.

Back

A type of reaction where two or more substances combine to form a new compound.

Front

Define Decomposition Reaction.

Back

A reaction where a single compound breaks down into two or more simpler products.

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another in a compound.

Front

What is a Double Replacement Reaction?

Back

A reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is Combustion?

Back

A reaction that typically involves oxygen and produces heat and light, often resulting in the formation of carbon dioxide and water.

Front

Example of a Synthesis Reaction.

Back

2H₂ + O₂ → 2H₂O (Hydrogen and oxygen combine to form water.)

Front

Example of a Decomposition Reaction.

Back

2H₂O → 2H₂ + O₂ (Water breaks down into hydrogen and oxygen.)

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; it is conserved.
