CHEMICAL REACTIONS: Types of Reactions and Balancing Practice
Balance each reaction, including atom counts. Use another sheet if needed. Then determine which type of chemical
reaction (synthesis, decomposition, single-replacement, or combustion) is being represented by each equation. REMEMBER:
A reaction can be more than one type. Explain the reason for your reaction type choice..
