Synthesis
Decomposition
Single displacement
Double displacement
3. A reaction where a compound breaks down into two or more simpler substances is called a reaction.
4. In a combustion reaction, a substance reacts with , usually producing heat and light.
5. Describe the key characteristics of a double displacement reaction and provide a balanced chemical equation as an example.
6. All redox reactions are also combustion reactions.
True
False
7. A single displacement reaction always involves a metal replacing a hydrogen atom from an acid.
True
False
Match the reaction type with its general form.
