Types of Reactions

Front

What is a Single Replacement Reaction?

Back

A chemical reaction where one element replaces another in a compound. Example: H2SO4 + Fe -> H2 + FeSO4.

Front

What is a Synthesis Reaction?

Back

A type of reaction where two or more reactants combine to form a single product. Example: 4Si + S8 -> 2Si2S4.

Front

What is a Decomposition Reaction?

Back

A reaction where a single compound breaks down into two or more simpler products. Example: 2Pb(NO3)2 -> 2PbO + 4NO2 + O2.

Front

What is a Double Replacement Reaction?

Back

A reaction where two compounds exchange ions or bonds to form two new compounds. Example: Not provided in the questions.

Front

How do you balance a chemical equation?

Back

By ensuring the number of atoms for each element is the same on both sides of the equation. Example: 2Li + Cl2 -> 2LiCl.

Front

What is the general form of a Synthesis Reaction?

Back

A + B -> AB, where A and B are reactants that combine to form a product AB.

Front

What is the general form of a Decomposition Reaction?

Back

AB -> A + B, where a compound AB breaks down into its components A and B.

Front

What is the general form of a Single Replacement Reaction?

Back

A + BC -> AC + B, where element A replaces element B in compound BC.

Front

What is the general form of a Double Replacement Reaction?

Back

AB + CD -> AD + CB, where the ions of two compounds exchange places.

Front

What is an example of a combustion reaction?

Back

A reaction where a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH4 + 2O2 -> CO2 + 2H2O.
