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: 4Si + S8 → 2Si2S4.

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: 3Ca + 2AlCl3 → 3CaCl2 + 2Al.

Front

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: 2Pb(NO3)2 → 2PbO + 4NO2 + O2.

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: NH3 + HCl → NH4Cl.

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure that the number of atoms for each element is the same on both sides of the equation.

Front

What is the coefficient for NO in the reaction N2 + O2 → ?NO to balance it?

Back

The coefficient for NO is 2, making the balanced equation: N2 + O2 → 2NO.

Front

What is the general form of a synthesis reaction?

Back

The general form of a synthesis reaction is 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

The general form of a decomposition reaction is AB → A + B, where a compound AB breaks down into its components A and B.

Front

What is the general form of a single displacement reaction?

Back

The general form of a single displacement reaction is A + BC → AC + B, where element A displaces element B in compound BC.

Front

What is the general form of a double displacement reaction?

Back

The general form of a double displacement reaction is AB + CD → AD + CB, where the ions of two compounds exchange places.
