Decomposition Reactions in Chemistry

This video tutorial covers decomposition reactions, explaining how a single reactant breaks down into multiple products. It provides examples using calcium carbonate, silver oxide, sodium chloride, potassium chlorate, and magnesium hydroxide. The video emphasizes the use of a reference sheet for predicting products and includes practice problems to reinforce learning.

What does the term 'decomposition' mean in the context of chemical reactions?

• Changing the state of a substance
