These worksheets look at all the different aspects of representing a chemical reaction.

Chemical reactions are happening all the time around use and we just don’t realize it. Ever clean your kitchen with something other than water? Ever rinse with mouth wash? Have you seen the glorious baking soda and vinegar volcano that is so popular at science fairs? Chemical reactions happen when molecules from one substance break apart and combine, to some degree, with another. This usually is irreversible and forms a new substance all together. Some reactions give off heat, like hand warmers. Some take in heat (get colder). Instant ice packs are an example of that. Some reactions give off brilliant colors. Where do you think firework reactions come from?

This group of sheets really focuses on understanding how a reaction can be understood from the molecular masses all the way through to diagramming the reaction that takes place.
