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.
When ignited, hydrogen gas combines with oxygen gas explosively in proportions ranging from 4.1 - 71.5% hydrogen - ignition temperature is ca. 580 Â°C. The gaseous reaction is. 2 H2(g) + O2(g) â 2 H2O(g) This exothermic reaction yields 232 kJ/mol of water formed.
