Types of Chemical Reactions

Front

What is a Single Replacement Reaction?

Back

A type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound. Example: Zn + 2HCl → ZnCl2 + H2.

Front

What is a Decomposition Reaction?

Back

A type of chemical reaction where a single compound breaks down into two or more simpler products. Example: CaCO3 → CaO + CO2.

Front

What is a Synthesis Reaction?

Back

A type of chemical reaction where two or more simple substances combine to form a more complex product. Example: 2H2 + O2 → 2H2O.

Front

What is a Double Replacement Reaction?

Back

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

Front

How can you identify a Single Replacement Reaction?

Back

It can be recognized by the general pattern: A + BC → AC + B.

Front

What does it mean for a chemical equation to be balanced?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, following the law of conservation of mass.

Front

What is the general form of a Decomposition Reaction?

Back

AB → A + B, where a compound breaks down into its components.

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.
