Balancing and Reaction Types

Front

What is a Decomposition Reaction?

Back

A reaction where a single compound breaks down into two or more simpler products. Example: H2O2 → H2O + O2.

Identify the coefficients needed to balance the reaction: Al + FeO → Al2O2 + Fe.

Back

2, 2, 2.

Front

What is the purpose of balancing chemical equations?

Back

To ensure that the number of atoms for each element is the same on both sides of the equation, following the Law of Conservation of Mass.

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another in a compound. Example: Zn + CuSO4 → ZnSO4 + Cu.

Front

What is a Combustion Reaction?

Back

A reaction where a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH4 + 2O2 → CO2 + 2H2O.
