Front

Define Synthesis (Combination) Reaction.

Back

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

Front

Example of a Synthesis Reaction.

Back

2H₂ + O₂ → 2H₂O (Hydrogen and oxygen combine to form water).

Front

Define Decomposition Reaction.

Back

A reaction where a single compound breaks down into two or more simpler products.

Front

Example of a Decomposition Reaction.

Back

2H₂O → 2H₂ + O₂ (Water decomposes into hydrogen and oxygen).

Front

Define Single Displacement Reaction.

Back

A reaction where one element displaces another in a compound.

Front

Example of a Single Displacement Reaction.

Back

Cu + 2AgNO₃ → Cu(NO₃)₂ + 2Ag (Copper displaces silver in silver nitrate).

Front

Define Double Displacement Reaction.

Back

A reaction where the anions and cations of two different compounds exchange places to form two new compounds.

Front

Example of a Double Displacement Reaction.

Back

Na₃PO₄ + 3KOH → 3NaOH + K₃PO₄ (Sodium phosphate reacts with potassium hydroxide).
