Flashcard 8 - Chemistry

Front

What is a double-displacement reaction?

Back

A double-displacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: BaCl₂(aq) + Na₂SO₄(aq) ⟶ 2 NaCl(aq) + BaSO₄(s).

Front

What is a decomposition reaction?

Back

A decomposition reaction is a chemical reaction where a single compound breaks down into two or more simpler products. Example: 2 H₂O₂(aq) ⟶ 2 H₂O(l) + O₂(g).

Front

What is a combination reaction?

Back

A combination reaction is a type of chemical reaction where two or more substances combine to form a single product. Example: 2 H₂ + O₂ ⟶ 2 H₂O.

Front

What is a single-displacement reaction?

Back

A single-displacement reaction is a chemical reaction where one element displaces another in a compound. Example: 2 Al + Fe₂O₃ ⟶ 2 Fe + Al₂O₃.

Front

What is the general form of a double-displacement reaction?

Back

The general form is AB + CD ⟶ AD + CB, where A and C are cations and B and D are anions.

Front

What is the general form of a decomposition reaction?

Back

The general form is AB ⟶ A + B, where a compound breaks down into its components.

Front

What is the general form of a combination reaction?

Back

The general form is A + B ⟶ AB, where two or more reactants combine to form a single product.

Front

What is the general form of a single-displacement reaction?

Back

The general form is A + BC ⟶ AC + B, where an element displaces another in a compound.

Front

What are spectator ions in a double-displacement reaction?

Back

Spectator ions are ions that do not participate in the actual chemical reaction and remain unchanged on both sides of the equation.

Front

What is the role of catalysts in chemical reactions?

Back

Catalysts speed up chemical reactions without being consumed in the process, lowering the activation energy required.
