Exploring Types of Chemical Reactions

What is a synthesis reaction?

• Reaction of a hydrocarbon with oxygen

• Combining simpler substances to form a complex compound

• Exchange of ions between two compounds

• Breaking down of a compound into simpler substances

Which reaction is represented by A + B -> AB?

• Synthesis

• Combustion

• Single Replacement

• Decomposition

What represents a decomposition reaction?

• A + B -> AB

• AB + CD -> AD + CB

• AB -> A + B

• A + BC -> B + AC

What does a decomposition reaction typically involve?

• Exchange of ions

• Formation of a complex compound from simpler substances

• Breakdown of a compound into simpler substances

• Formation of water

What is a characteristic of a single replacement reaction?

• Two elements exchange partners

• One element replaces another in a compound

In a cationic single replacement reaction, what type of ion does the metal replace?

• A non-metal ion

• A metal ion

• A negatively charged ion

• A positively charged ion

In a single replacement reaction, what can be said about the reactants?

• They are both compounds forming a more complex compound

• They involve a hydrocarbon and oxygen

• They consist of a single element and a compound

• They involve two compounds exchanging ions

What happens in a double replacement reaction?

• A compound decomposes into simpler substances

• A single element replaces another in a compound

• A hydrocarbon reacts with oxygen

What is the outcome of a double replacement reaction?

• Formation of a single compound

• Breakdown into simpler substances

• Formation of two new compounds

• Release of energy without changing compounds

What are the products of a combustion reaction involving hydrocarbons?
