In this video, the man puts a balloon filled with baking soda over a bottle of vinegar. You can see that the vinegar immediately starts to bubble up and fizz, in turn filling up the balloon. This chemical reaction between baking soda and vinegar creates a gas/fizz, proving a chemical change. The chemical equation for this reaction is CH3COOH + NaHCO3 = CH3COONa + CO2 + H2O.

This video shows an Elephant Toothpaste reaction, or a reaction between hydrogen peroxide and potassium iodide. In this reaction, the substances are poured into a beaker and immediately start foaming up, spraying out of the container. You can also see the steam from the gas created off of the "Elephant Toothpaste". The chemical equation for this is H2O2 + KI.

In this chemical reaction lighter fluid, sand, baking soda, and sugar are put on a plate and lit on fire. Then, a new substance that looks like a snake emerges from the mixture. The new substance forming is proof of a chemical change. The chemical equation for this reaction is C12H22O11 + 12O2 → 12CO2 + 11H2O (g).
