Types of Chemical Reactions Review

Front

What is a Single Replacement Reaction?

Back

A chemical reaction where one element replaces another in a compound. Example: H2SO4 + Fe -> H2 + FeSO4.

Front

What is a Decomposition Reaction?

Back

A reaction where a single compound breaks down into two or more simpler products. Example: 2Pb(NO3)2 -> 2PbO + 4NO2 + O2.

Front

What does the arrow in a chemical equation represent?

Back

The arrow indicates the direction of the reaction, showing the reactants transforming into products. It is often read as 'yields'.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more reactants combine to form a single product. Example: 3Mg + N2 -> Mg3N2.

Front

What is a Combustion Reaction?

Back

A reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH4 + 2O2 -> CO2 + 2H2O.

Front

What are Reactants in a chemical equation?

Back

The starting substances that undergo a chemical change in a reaction, found on the left side of the equation.

Front

What are Products in a chemical equation?

Back

The substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

What is the Law of Conservation of Mass?

Back

In a chemical reaction, mass is neither created nor destroyed; the total mass of reactants equals the total mass of products.

Front

What is a Double Replacement Reaction?

Back

A reaction where two compounds exchange ions or bonds to form two new compounds. Example: AB + CD -> AD + CB.

Front

What is an example of a chemical equation for a Synthesis Reaction?

Back

An example is: 2H2 + O2 -> 2H2O.
