Types of Chemical Reactions

Front

What is an element?

Back

An element is a pure substance that cannot be broken down into simpler substances by chemical means. Examples include carbon (C), oxygen (O), and gold (Au).

Front

What is a compound?

Back

A compound is a substance formed when two or more elements are chemically bonded together. An example is sodium chloride (NaCl), which is made of sodium (Na) and chlorine (Cl).

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that in a chemical reaction, the total mass of the reactants is equal to the total mass of the products.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that involves the rearrangement of the molecular or ionic structure of a substance, resulting in the formation of new substances.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a hydrocarbon reacts with oxygen, producing carbon dioxide and water.

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 substance.

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 single replacement reaction?

Back

A single replacement reaction is a type of 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 type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What is the general formula for a single replacement reaction?

Back

The general formula for a single replacement reaction is A + BC → B + AC.
