What will happen if hydrogen and oxygen combined?
When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. For both of the reactions shown, the hydrogen molecules are oxidized and the oxygen atoms are reduced.
What happens when hydrogen and oxygen combust?
The chemical reaction was a simple one: hydrogen combining with oxygen to produce water. The products of the combustion of hydrocarbons are carbon dioxide and water. Many hydrocarbons are used as fuel because their combustion releases very large amounts of heat energy.
Can hydrogen and oxygen make fire?
As we discussed earlier, hydrogen gas is highly flammable. All it needs is an oxidant to start burning. Since oxygen is the most abundant oxidant on Earth, it rapidly combines with hydrogen atoms to catch ‘fire’, if you will.
Why does a mixture of hydrogen and oxygen in a balloon not spontaneously explode at room temperature?
Thermodynamically, the reaction between hydrogen and oxygen is very favorable. However, a balloon filled with hydrogen and oxygen at room temperature will remain inert indefinitely. Kinetically, one must apply an energy of some kind in order to get the reaction started.
Why does hydrogen make a squeaky pop?
Hydrogen gas is highly flammable . You can safely test for small quantities of hydrogen gas (eg collected in a test tube) by holding a burning splint near to the top of the test tube. The positive result is a squeaky pop sound as the hydrogen reacts with oxygen in the air in a small explosion.
Why is hydrogen explosive?
Hydrogen gas is very flammable. The heat given off by the candle provides the activation energy required for the reaction that produces water from hydrogen and oxygen. This reaction is highly exothermic, producing the prodigious explosion.
Why do hydrogen balloons explode?
Hydrogen gas is very flammable. This is why the balloon filled with hydrogen ignites. The heat given off by the candle provides the activation energy required for the reaction that produces water from hydrogen and oxygen. This reaction is highly exothermic, producing the prodigious explosion.
Why is hydrogen so explosive?
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.
