As a chemical expert with a deep understanding of the principles of combustion and explosions, I can provide a comprehensive explanation of why hydrogen and oxygen explode when they are mixed together.
Hydrogen is a highly flammable gas that reacts vigorously with oxygen, which is an oxidizer. The reaction between hydrogen and oxygen is a rapid oxidation-reduction, or redox, process that produces water as a byproduct. This reaction is exothermic, meaning it releases a significant amount of heat. When hydrogen and oxygen are combined in the right proportions, the reaction can be extremely rapid and energetic, leading to an explosion.
The explosion occurs because the energy released by the reaction is greater than the energy required to break the chemical bonds in the reactants. This excess energy is then released in the form of heat and light, which can cause a rapid expansion of gases. The speed at which the reaction takes place is a critical factor in determining whether a mixture of hydrogen and oxygen will explode. If the reaction is too slow, the heat generated may dissipate before it can cause an explosion. However, if the reaction is too fast, the rapid release of energy can lead to a violent explosion.
The conditions necessary for an explosion to occur are often referred to as the "explosive limits." For hydrogen in air, the explosive limits are between 4% and 75% by volume. This means that if the concentration of hydrogen in the air is within this range, an ignition source can trigger an explosion. The exact concentration at which an explosion will occur can vary depending on factors such as temperature, pressure, and the presence of other chemicals.
Safety precautions are paramount when working with hydrogen and oxygen. It is essential to conduct tests to determine the optimal volume ratios for the gases in a controlled environment, such as within balloons, to ensure that the sound of the explosion is tolerable and does not pose a risk to those in the vicinity. This is particularly important in a demonstration setting, where the goal is to educate and inform without causing harm.
In summary, the explosion of hydrogen and oxygen is a result of a rapid and exothermic redox reaction that releases a large amount of energy. Understanding the conditions that lead to these explosions and taking appropriate safety measures are crucial for preventing accidents and ensuring the safe handling of these gases.

Hydrogen gas is very flammable and yields explosive mixtures with air and oxygen. The explosion of the mixture of hydrogen and oxygen is quite loud. Tests should be made prior to the demonstration to adjust the total volume in the balloons so that the sound of the explosion is tolerable in the room.
