Types of chemical reactions

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: Al(OH)3 → Al2O3 + H2O.

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: C2H2 + O2 → CO2 + H2O.

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: 2Na + S → Na2S.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: A + BC → AC + B.

Front

What evidence indicates an exothermic reaction?

Back

An exothermic reaction releases heat, which can be indicated by a temperature increase during the reaction.

Front

What is the general form of a decomposition reaction?

Back

The general form of a decomposition reaction is AB → A + B, where a compound breaks down into its elements or simpler compounds.

Front

What is the general form of a synthesis reaction?

Back

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

Front

What is the general form of a combustion reaction?

Back

The general form of a combustion reaction is Hydrocarbon + O2 → CO2 + H2O, where a hydrocarbon reacts with oxygen to produce carbon dioxide and water.

Front

What is the general form of a single replacement reaction?

Back

The general form of a single replacement reaction is A + BC → AC + B, where an element replaces another in a compound.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, resulting in a temperature decrease.
