Double Replacement Reactions

What are the five types of chemical reactions?

• Synthesis, Decomposition, Single Replacement, Double Replacement, Combustion

• Addition, Subtraction, Multiplication, Division, Modulus

• Oxidation, Reduction, Hydrolysis, Condensation, Neutralization

• Endothermic, Exothermic, Photochemical, Electrochemical, Biochemical

The general format of a synthesis reaction is:

• A + B → AB

• AB → A + B

• A + B → A

• AB + C → AC + B

The general form of a decomposition reaction is:

• AB → A + B

• A + B → AB

• AB + C → AC + B

• A → B + C

How can you identify a single replacement reaction?

• By observing the exchange of ions between two compounds

• By identifying a single element replacing another in a compound

• By detecting the formation of a precipitate

• By measuring the change in temperature

What chart should you consult to determine if a single replacement reaction will occur?

• Activity series chart

• Periodic table

• Solubility chart

• Molecular weight chart

For a single replacement reaction to take place, the single metal must be ________ (more, less) reactive than the metal in the compound.

For a precipitation (double replacement) reaction to occur, you must refer to the ________ table to check if any of the products are insoluble.

For a precipitation (double replacement) reaction, if both products are ________, we say there is no reaction.

• soluble

• insoluble

• gaseous

• liquid

A combustion reaction must have ________ as one of the reactants. The other reactants must contain ________ and ________.

The products of a combustion reaction are always ________ and ________.

• carbon dioxide, water
