Chemical Reactions 2

This past week in class, we started learning about our next unit, Chemical Reactions. You can tell when a chemical change is occurring thanks to sensory clues. These are things such as:
-color change
-a solid forms
-bubbles form
-heat/flame is produced or abso


In a chemical reaction equation, there will be a small letter(s) after each compound, telling you what state it's in. These are:
-g (gas)
-l (liquid)
-s (solid)
-aq (aqueous)

Here is an example of what one of these equations might look like:
