12 Amazing Chemical Reactions



Let's begin with the thought of a chemical reaction. Reactions occur when several molecules interact and the molecules change. Bonds between atoms will be broken and created to form new molecules.
When you have a chemical change you just get a change in appearance only and the object has all the same properties.

When you have a chemical reaction a new substance is created because of bonds and broken and reformed. A chemical reaction will leave clues that they have occurred.
Here are five clues of a chemical reaction.

  • Fizzing or bubbles are released.
  • A change in temperature without adding a heat source.
  • A change in color
  • A change in odor
  • An explosion
Sometimes when you mix certain chemicals you will get an amazing explosion. There is a tremendous amount of energy stored in chemical bonds and sometimes when these are broken it can be very violent.


  • Mixing baking soda and vinegar results in a lot of fizzing but no explosion.
  • If you place sodium in water it will actually catch on fire.
  • If you place cesium and water you get an awesome explosion.
  • Another chemical reaction we often don’t think about is when you mix gasoline and fire.
  • You can drop a gummy bear into a test tube filled with potassium chlorate and you get smoking and a nice explosion.

Chemical reactions are all around us in life. When they occur they leave behind clues and a new substance is created.
