Uses for these chemical reactions can be used for the extinguishing of fires in small/medium scales using the hydrochloric acid and sodium bicarbonate. Also, for example during survival instances, you can use the hydrogen peroxide and potassium iodide for fire starting.

Part 1:  Calcium metal and water. When we combined them, it created hydrogen gas and the hydrogen gas was able to ignite the whole cylinder. This happens because is highly reactive with flames.

Part 2: Hydrogen peroxide and potassium iodide. When they combine, mass amounts of oxygen are released. This allowed the ember on the wooden stick to ignite into a full flame.

Part 3: Sodium carbonate and hydrochloric acid. The combination of the 2 makes carbon dioxide. This allowed for the fire to be extinguished very quickly and easily once dropped into the cylinder.

The first video is from Part 1. The second is from Part 4.
