When these _______________ combine in exact ways, like a recipe, they form into
When 2 or more kinds of _______________ bond together and form these new compounds, what happened is called a
Can you match the elements to their symbols?
Some are boring to watch
Some are more fun and amazing!
Let’s watch some fun chemistry reactions
Magnesium metal + Hydrochloric acid Magnesium Chloride solution + Hydrogen gas
This reaction gets hotter (energy is released too)
The gas can be caught in another test tube.
The test for hydrogen gas makes a loud pop!
The hydrogen gas was “hiding” in the solution and the chemical reaction let it come out.
Elephant Toothpaste Chloride solution + Hydrogen gas
Hydrogen peroxide solution with a catalyst will form water and oxygen gas, with energy (heat) also released.
This is called exothermic decomposition.
Vinegar Chloride solution + Hydrogen gas + Baking Soda makes
a salty water solution + carbon dioxide gas
Vinegar is an acid.
The baking soda is a base.
They will neutralize each other and make bubbles!

Do not try any experiments without your parents permission, ever!
Always study hard to learn a lot.
Always listen to your teachers and your parents.
Thank you for letting me come in, do you have any questions now?
