This edition: Chemical Reactions: Atoms Find New Partners
The presence of ongoing change is a reality we cannot escape, but most change is related to chemistry and takes place at a level you can’t see. This lesson explores three key topics:
How to identify whether a chemical or physical change has occurred. How to classify chemical reactions into categories to help predict the outcome. How to calculate substances to ensure the necessary amounts of the ingredients are used and the desired amount of material is created.
Without knowledge of these three topics, life in our world would be very different since most of items we use everyday were created using principles related to these topics.
