Chemical Reactions

You pour a blue liquid into a red liquid. After the bubbling and frothing stop the mixture becomes yellow. What happened? A chemical reaction!

Not everything will react with each other. Some things just mix together like chocolate and milk.

Not all reactions will bubble and froth but all chemical reactions cause a chemical change. The chemical change means that the molecules that interacted are no longer there but they have combined in a new way to form other molecules.

Here are some examples of chemical reactions you may have seen before:
Rusty Nails: A chemical reaction causes metal rust.
Photographic film: There is a chemical reaction on the film wherever light hits it.
Batteries: Chemical reactions within batteries produce the electricity.
Halloween Lightsticks: A chemical reaction causes the stick to glow.
