Types of Reactions

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product. Example: P4 + 3O2 → 2P2O3.

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: 2NO2 → N2 + 2O2.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: Fe + H2SO4 → Fe2(SO4)3 + H2.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: PbCl2 + AgNO3 → Pb(NO3)2 + AgCl.

What are the general characteristics of synthesis reactions?

Back

Synthesis reactions typically involve the formation of a single product from multiple reactants and are often exothermic.

Front

What are the general characteristics of decomposition reactions?

Back

Decomposition reactions usually require energy input (heat, light, or electricity) and result in the formation of simpler substances.

Front

What are the general characteristics of single replacement reactions?

Back

Single replacement reactions involve an element and a compound, where the element displaces another element in the compound.

Front

What are the general characteristics of double replacement reactions?

Back

Double replacement reactions typically occur in aqueous solutions and involve the exchange of ions between two compounds.

What is an example of a synthesis reaction?

Back

An example of a synthesis reaction is: 2H2 + O2 → 2H2O.

What is an example of a decomposition reaction?

Back

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