Inform them that the yellow balloon contained hydrogen. The hydrogen mixes with oxygen in the air forming an explosive mixture. Because the hydrogen and oxygen must mix before an explosion can occur, the explosion is relatively slow and diffuse. Point out that the remote candle is still lit.
Hydrogen occurs as a gas that you canât see and canât smell. It is about 14 times lighter than air. When you combine two atoms of hydrogen with one atom of oxygen you get a water molecule H 2O. Like nitrogen, hydrogen can also be condensed to a liquid that freezes at â 259Â°C (-434Â°F) and boils at -252Â°C (-423Â°F). Hydrogen is one of the most common elements in our universe. The sun and many stars are made of hydrogen.
