Types of Reactions & predicting Products

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another in a compound. Example: Fe + CuSO4 → Cu + FeSO4.

Front

What is a Double Replacement Reaction?

Back

A reaction where two compounds exchange ions or bonds to form two new compounds. Example: AgNO3 + NaCl → AgCl + NaNO3.

Front

What is a Decomposition Reaction?

Back

A reaction where a single compound breaks down into two or more simpler products. Example: 2H2O2 → 2H2O + O2.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more simple substances combine to form a more complex product. Example: 2H2 + O2 → 2H2O.

Front

What is a Combustion Reaction?

Back

A reaction that involves the burning of a substance in the presence of oxygen, producing heat and light. Example: CH4 + 2O2 → CO2 + 2H2O.

Front

What are the signs of a chemical reaction?

Back

Color change, temperature change, gas production, and formation of a precipitate.

Front

How do you predict the products of a Single Replacement Reaction?

Back

Identify if the free element can displace the element in the compound based on reactivity.

Front

How do you predict the products of a Double Replacement Reaction?

Back

Exchange the ions of the two compounds to form new compounds.

Front

What is the Law of Conservation of Mass?

Back

In a chemical reaction, mass is neither created nor destroyed; it remains constant.

Front

What is an example of a Synthesis Reaction?

Back

Formation of water: 2H2 + O2 → 2H2O.
