Classifying Chemical Reactions Warm-Up 2023-24

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one compound breaks down into two or more simpler products. Example: 2H₂SO₄ → 2H₂O + SO₂ + O₂.

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: NaCl + AgNO₃ → NaNO₃ + AgCl.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. Example: 2Hg + Cl₂ → 2HgCl₂.

Front

What is a combustion reaction?

Back

A combustion reaction is a type of chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: 2H₂ + O₂ → 2H₂O.

Front

What are the four main types of chemical reactions?

Back

The four main types of chemical reactions are: 1) Synthesis, 2) Decomposition, 3) Single Displacement, 4) Double Displacement.

Front

What is a single displacement reaction?

Back

A single displacement reaction is a type of chemical reaction where one element displaces another in a compound. Example: Zn + 2HCl → ZnCl₂ + H₂.

Front

How can you identify a decomposition reaction?

Back

A decomposition reaction can be identified by the presence of a single reactant that breaks down into two or more products.

Front

What is the general form of a synthesis reaction?

Back

The general form of a synthesis reaction is A + B → AB, where A and B are reactants that combine to form a single product AB.

Front

What is the general form of a double displacement reaction?

Back

The general form of a double displacement reaction is AB + CD → AD + CB, where two compounds exchange components.

Front

What is the role of energy in combustion reactions?

Back

In combustion reactions, energy is released in the form of heat and light when a substance reacts with oxygen.
