What is an Acid-Base Reaction?

Back

An Acid-Base Reaction is a chemical reaction that occurs between an acid and a base, resulting in the formation of water and a salt. Example: H₂SO₄ + 2KOH → 2H₂O + K₂SO₄.

What is a Redox Reaction?

Back

A Redox Reaction (reduction-oxidation reaction) involves the transfer of electrons between two species, resulting in changes in oxidation states. Example: Zn + 2AgNO₃ → Zn(NO₃)₂ + 2Ag.

Front

What is a Decomposition Reaction?

Back

A Decomposition Reaction is a type of chemical reaction where one reactant breaks down into two or more products. Example: 2KClO₃ → 2KCl + 3O₂.

Front

What is a Combustion Reaction?

Back

A Combustion Reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat. Example: C₃H₈ + 5O₂ → 3CO₂ + 4H₂O.

Front

What is a Synthesis Reaction?

Back

A Synthesis Reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product. Example: A + B → AB.

Front

What is a Single Replacement Reaction?

Back

A Single Replacement Reaction is a chemical reaction where one element replaces another in a compound. Example: A + BC → AC + B.

Front

What is a Double Replacement Reaction?

Back

A Double Replacement Reaction is a chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: AB + CD → AD + CB.

Front

What is the role of water in Acid-Base Reactions?

Back

Water is produced as a byproduct in Acid-Base Reactions, indicating the neutralization of an acid by a base.

Front

How can you identify a Redox Reaction?

Back

You can identify a Redox Reaction by looking for changes in oxidation states of the reactants.

Front

What is the general form of a Decomposition Reaction?

Back

The general form of a Decomposition Reaction is: AB → A + B.
