Can you combine hydrogen and oxygen for water?
Just mixing hydrogen and oxygen together doesn’t make water – to join them together you need energy. The trouble with adding energy into the equation is that a large-scale chemical reaction of flammable hydrogen and oxygen (which is what keeps a fire burning) is likely to result in a rather large explosion.
How does oxygen and hydrogen combine to form water?
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. In this oxidation, a molecule of hydrogen gas is ionized to two electrons and two protons.
What will happen if hydrogen and oxygen combine?
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. These two processes are represented by the two chemical equations shown at right.
Can water be man made?
Is it possible to make water? Theoretically, it is possible. You would need to combine two moles of hydrogen gas and one mole of oxygen gas to turn them into water. However, you need activation energy to join them together and start the reaction.
When hydrogen and oxygen change to water does it give off?
The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.
Is making hydrogen from water a physical change?
Changing the size and shapes of pieces or wood would be a chemical change. In a physical change, the makeup of matter is changed. Combining hydrogen and oxygen to make water is a physical change.
Is oxygen a physical change or chemical change?
In this example, you may see bubbles of oxygen (O2) gas. Those bubbles are evidence of the chemical changes. Melting a sugar cube is a physical change because the substance is still sugar. Burning a sugar cube is a chemical change.
Did the Hindenburg explosion create water?
Yes, water was created. But, because of the heat of reaction, all of the water was vapor (gas) and it did not rain water. Reaction of hydrogen with oxygen in the air always results in water as the product. The Hindenburg exploded due to the rapid combustion of hydrogen.
Is oxygen and hydrogen water a chemical change?
The synthesis of water The synthesis (forming) of water (H2O) from hydrogen gas (H2) and oxygen gas (O2) is another example of chemical change.
Can we create water in lab?
While making small volumes of pure water in a lab is possible, it’s not practical to “make” large volumes of water by mixing hydrogen and oxygen together. The reaction is expensive, releases lots of energy, and can cause really massive explosions.
Is it possible to combine hydrogen and oxygen to make water?
A hydrogen fuel cell can be used to combine hydrogen and oxygen to make water without creating an explosion. QUESTION : Why can’t we combine hydrogen and oxygen to make water?
Can hydrogen and oxygen be used to make water without explosion?
A hydrogen fuel cell can be used to combine hydrogen and oxygen to make water without creating an explosion. Yes, if we use what is called a hydrogen fuel cell. A hydrogen fuel cell is kind of like a battery that needs a continuous input of hydrogen and oxygen gas to make electrical energy, with water as the only output.
Why does oxygen have to be heated to make water?
Oxygen is usually present as O 2 (two oxygen atoms bonded together), so in order to make water (H2O) the two oxygen atoms in O2 must break apart, and that takes extra energy. This energy can come from a couple places. Adding heat (like a spark) will give the necessary energy to get the reaction started so a couple O 2 molecules to break…
What happens when you mix hydrogen & oxygen at room temperature?
Merely mixing the two gases at room temperature, however, won’t do anything, like hydrogen and oxygen molecules in the air don’t spontaneously form water. Energy must be supplied to break the covalent bonds that hold H 2 and O 2 molecules together.
