Exercise
Form 8: Thermal Decomposition & Combustion
In this engaging exercise, students will explore the processes of thermal decomposition and combustion through hands-on experiments, interactive simulations, and real-world applications, enhancing their understanding of chemical reactions and energy transformations. Participants will analyze the differences between these two processes, investigate various substances, and creatively present their findings to reinforce their learning.
