types of reactions

Front

What is a Decomposition Reaction?

Back

A chemical reaction where a single compound breaks down into two or more simpler products. Example: Al(OH)3 → Al2O3 + H2O.

Front

What is a Synthesis Reaction?

Back

A chemical reaction where two or more simple substances combine to form a more complex product. Example: NH3 + HCl → NH4Cl.

Front

What is a Single Replacement Reaction?

Back

A chemical reaction where one element replaces another in a compound. Example: Mg + 2H2O → Mg(OH)2 + H2.

Front

What is a Double Replacement Reaction?

Back

A chemical reaction where ions in two compounds exchange places. Example: PbCl2 + AgNO3 → Pb(NO3)2 + AgCl.

Front

What is a Chemical Change?

Back

A process where substances transform into different substances with different properties. Example: Using magnesium to displace hydrogen gas from water.

What is the general form of a Decomposition Reaction?

Back

AB → A + B, where AB is a compound that breaks down into its elements or simpler compounds.

Front

What is the general form of a Synthesis Reaction?

Back

A + B → AB, where two or more reactants combine to form a single product.

Front

What is the general form of a Single Replacement Reaction?

Back

A + BC → AC + B, where an element replaces another in a compound.

Front

What is the general form of a Double Replacement Reaction?

Back

AB + CD → AD + CB, where the anions and cations of two different compounds exchange places.

What is an example of a Decomposition Reaction?

Back

2H2O2 → 2H2O + O2, where hydrogen peroxide decomposes into water and oxygen.
