Unit 4: Types of Reactions and Balancing Review

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.

Front

What is the general form of a Double Replacement Reaction?

Back

AB + CD → AD + CB, where A and C are cations and B and D are anions.

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another element in a compound.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more reactants combine to form a single product.

Front

What is a Combustion Reaction?

Back

A reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat.

Front

What does it mean for a reaction to be balanced?

Back

A balanced reaction has the same number of each type of atom on both sides of the equation.

Front

What is the purpose of balancing chemical equations?

Back

To obey the Law of Conservation of Mass, which states that matter cannot be created or destroyed.

Front

What are the products of the reaction: MgCl₂ + AgNO₃?

Back

AgCl(s) + Mg(NO₃)₂(aq) - a Double Replacement Reaction.

Front

What is the significance of coefficients in a chemical equation?

Back

Coefficients indicate the number of moles of each substance involved in the reaction.

Front

How do you determine if a reaction will occur?

Back

By using solubility rules, activity series, and recognizing reaction types.
