Types of Chemical Reactions

Front

What is a Double Replacement Reaction?

Back

A chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: KOH + H3PO4 → K3PO4 + H2O.

Front

What is a Combustion Reaction?

Back

A chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: CxHy + O2 → H2O + CO2.

Front

What is a Decomposition Reaction?

Back

A reaction where one reactant breaks down into two or more products. Example: 2H2O → 2H2 + O2.

Front

What are Reactants in a chemical equation?

Back

The substances that undergo a chemical change, found on the left side of the equation. Example: In H2 + O2 → H2O, H2 and O2 are reactants.

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another in a compound. Example: A + BC → AC + B.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more simple substances combine to form a more complex product. Example: A + B → AB.

Front

What is the general form of a chemical equation?

Back

A representation of a chemical reaction using symbols and formulas. Example: Reactants → Products.

Front

What is the role of a catalyst in a chemical reaction?

Back

A substance that increases the rate of a reaction without being consumed in the process.

Front

What is the Law of Conservation of Mass?

Back

In a chemical reaction, mass is neither created nor destroyed; it is conserved.

Front

What is an Exothermic Reaction?

Back

A reaction that releases energy, usually in the form of heat. Example: Combustion of fuels.
