Types of Chemical Reactions

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance (usually a hydrocarbon) reacts with oxygen to produce carbon dioxide and water, releasing energy in the form of heat and light.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products.

Front

What is a synthesis (combination) reaction?

Back

A synthesis reaction is a chemical reaction in which two or more reactants combine to form a single product.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a chemical reaction where one element replaces another element in a compound.

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.

Front

What are reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical reaction, found on the left side of the equation.

Front

What are 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 does the arrow in a chemical equation represent?

Back

The arrow in a chemical equation represents the direction of the reaction, indicating that reactants are transformed into products.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

What is an example of a combustion reaction?

Back

An example of a combustion reaction is the burning of methane: CH₄ + 2O₂ → CO₂ + 2H₂O.
