Classifying Reactions

Match the following reactions

• Single-Replacement

• A reaction in which two ionic compound reactants switch ions, forming two new ionic compound products

• Combustion

• 2 or more reactants combine to make 1 product

• Double-Replacement

• A reaction in which one element replaces a similar element in a compound

• Decomposition

• 1 reactant breaks down into 2 or more products

• Synthesis

A new compound is formed by the combination of simpler reactants, such as nitrogen dioxide and oxygen combine (a component of smog) forming in the atmosphere. This is a ​ (a)  

• synthesis reaction

• decomposition reaction

• combustion reaction

Answer explanation

The question describes a process where simpler reactants, nitrogen dioxide and oxygen, combine to form a new compound. This is a characteristic of a synthesis reaction, where two or more simple substances combine to form a more complex substance. Therefore, the correct answer is 'synthesis reaction'.

When one element replaces a similar element in a compound, it is an example of which type of chemical reaction?

• Synthesis

• Decomposition

• Combustion

• Single-Replacement
