Chemical Reaction Types

Front

What is the law of conservation of mass?

Back

Matter and mass cannot be created or destroyed.

Front

What type of reaction is represented by the equation 4Si + S8 --> 2Si2S4?

Back

Synthesis

Front

What type of reaction involves the ions of two compounds exchanging places to form two new compounds?

Back

Double replacement.

Front

What is the general form of a synthesis reaction?

Back

A + B = AB.

Front

What type of reaction breaks down a compound into two or more substances?

Back

Decomposition.

Front

What is a combustion reaction?

Back

A reaction that involves oxygen and produces energy, typically in the form of heat and light.

Front

What is a single replacement reaction?

Back

A reaction where one element replaces another in a compound.

Front

What is the general form of a double replacement reaction?

Back

AB + CD = AD + CB.

Front

What is an example of a decomposition reaction?

Back

2H2O -> 2H2 + O2.

Front

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

Back

Synthesis combines elements/compounds to form one product, while decomposition breaks down a compound into simpler substances.
