types of reactions

Front

What is a Double Displacement Reaction?

Back

A type of reaction where ions from two compounds exchange places to form two new compounds.

Front

What is a Decomposition Reaction?

Back

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

Front

What is a Single Displacement Reaction?

Back

A reaction where one element displaces another in a compound, forming a new compound and releasing the displaced element.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more reactants combine to form a single product.

Front

What is an example of a chemical change?

Back

Using magnesium to displace hydrogen gas from water.

Front

What is the generalized equation for a decomposition reaction?

Back

AB → A + B.

Front

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form of a substance without changing its chemical composition, while a chemical change results in the formation of new substances.

Front

What is a Combustion Reaction?

Back

A reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat.

Front

What is the role of catalysts in chemical reactions?

Back

Catalysts speed up chemical reactions without being consumed in the process.

Front

What is an example of a Synthesis Reaction?

Back

2H₂ + O₂ → 2H₂O (formation of water from hydrogen and oxygen).
