Reaction types

Front

What is a Decomposition Reaction?

Back

A reaction where a single compound breaks down into two or more simpler products. Example: H₂O₂ → H₂O + O₂.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more reactants combine to form a single product. Example: 2 Na + Cl₂ → 2 NaCl.

Front

What is a Double Replacement Reaction?

Back

A reaction where two compounds exchange ions to form two new compounds. Example: BaCl₂ + Na₂SO₄ → BaSO₄ + 2 NaCl.

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another in a compound. Example: Zn + CuSO₄ → ZnSO₄ + Cu.

Front

What is a Combustion Reaction?

Back

A reaction where a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH₄ + 2 O₂ → CO₂ + 2 H₂O.

Front

What is the general form of a Synthesis Reaction?

Back

A + B → AB, where A and B are reactants and AB is the product.

Front

What is the general form of a Decomposition Reaction?

Back

AB → A + B, where AB is the compound that decomposes into its elements.

Front

What is the role of reactants in a chemical equation?

Back

Reactants are the starting substances that undergo a chemical change, found on the left side of the equation.

Front

What is the role of products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

What is a Neutralization Reaction?

Back

A reaction between an acid and a base that produces water and a salt. Example: HCl + NaOH → NaCl + H₂O.
