Types of Reactions

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: 2H₂ + O₂ → 2H₂O.

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: 2H₂O → 2H₂ + O₂.

Front

What is a Single Displacement Reaction?

Back

A single displacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: Zn + 2HCl → ZnCl₂ + H₂.

Front

What is a Double Displacement Reaction?

Back

A double displacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: AgNO₃ + NaCl → AgCl + NaNO₃.

What are Reactants in a Chemical Reaction?

Back

Reactants are the starting substances in a chemical reaction that undergo change to form products.

Front

What are Products in a Chemical Reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

What is the Law of Conservation of Mass?

Back

The Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction; the mass of the reactants equals the mass of the products.

What is an example of a Synthesis Reaction?

Back

An example of a synthesis reaction is: 2Na + Cl₂ → 2NaCl.

Front

What is an example of a Decomposition Reaction?

Back

An example of a decomposition reaction is: CaCO₃ → CaO + CO₂.

Front

What is an example of a Single Displacement Reaction?

Back

An example of a single displacement reaction is: Cu + 2AgNO₃ → Cu(NO₃)₂ + 2Ag.
