Unit 3 Flashcard Reaction Types & Balancing Equations

Front

What is a Synthesis (Combination) Reaction?

Back

A reaction where two or more reactants combine to form a single product. Example: A + B → AB.

Front

What is a Decomposition Reaction?

Back

A reaction where a single reactant breaks down into two or more products. Example: AB → A + B.

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another in a compound. Example: A + BC → AC + B.

Front

What is a Double Replacement Reaction?

Back

A reaction where parts of two compounds exchange places to form two new compounds. Example: AB + CD → AD + CB.

Front

What is a Combustion Reaction?

Back

A reaction that involves the burning of a substance in the presence of oxygen, producing heat and light. Example: Hydrocarbon + O₂ → CO₂ + H₂O.

Front

How do you determine if a chemical equation is balanced?

Back

A chemical equation is balanced when the number of atoms of each element is the same on both sides of the equation.

What is the general formula for a Synthesis Reaction?

Back

A + B → AB.

What is the general formula for a Decomposition Reaction?

Back

AB → A + B.
