Chemical Reaction Types

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 substances.

Front

What is the general formula for a double replacement reaction?

Back

The general formula for a double replacement reaction is AB + CD → AD + CB, where two compounds exchange components.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that matter and mass cannot be created or destroyed in a chemical reaction.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, producing heat and light, typically resulting in carbon dioxide and water.

Front

What are the products of the combustion of propane (C3H8)?

Back

The products of the combustion of propane (C3H8) are carbon dioxide (CO2) and water (H2O).

Front

What is the difference between a synthesis reaction and a decomposition reaction?

Back

A synthesis reaction involves two or more substances combining to form a new compound, while a decomposition reaction involves a single compound breaking down into simpler substances.

Front

What is an example of a single replacement reaction?

Back

An example of a single replacement reaction is when zinc reacts with hydrochloric acid: Zn + 2HCl → ZnCl2 + H2.

Front

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

Back

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

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings.
