What happens when two parts hydrogen and two parts 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. In this oxidation, a molecule of hydrogen gas is ionized to two electrons and two protons.

What type of reaction is it when he combines hydrogen and oxygen to form water?

When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed. An example of a simple chemical reaction is the breaking down of hydrogen peroxide molecules, each of which consists of two hydrogen atoms bonded to two oxygen atoms (H2O2).

What does hydrogen combine with when it burns?

The most common substance resulting from hydrogen combustion is water. The hydrogen atoms mix with the oxygen atoms and create the essential H20 formula, resulting in a light residue of water that may escape as water vapor or condense on surfaces near where the hydrogen is burned.

Can you create water with hydrogen and oxygen?

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.

Does combining hydrogen and oxygen make water a physical change?

In a physical change, the makeup of matter is changed. Evaporation occurs when liquid water changes into a gas. Combining hydrogen and oxygen to make water is a physical change. Breaking up concrete is a physical change.

How does hydrogen and oxygen make water?

In theory, it’s easy to make water from hydrogen gas and oxygen gas. Mix the two gases together, add a spark or sufficient heat to provide the activation energy to start the reaction, and presto—instant water. When the chemical bonds re-form to make water, additional energy is released, which propagates the reaction.

How does hydrogen and oxygen become water?

Is hydrogen and oxygen water?

Water is made up of hydrogen and oxygen, and it exists in gaseous, liquid, and solid states.

How do you make water from two hydrogen atoms?

But you can’t simply take two hydrogen atoms and stick them onto an oxygen atom. 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).

What happens when hydrogen reacts with oxygen to produce water?

There are some experiments that can be done that confirm that two parts hydrogen react with one part oxygen to produce water. If you were to mix in a container a volume of oxygen gas and double that volume of hydrogen gas and ignited it, it would all be consumed and turned into water.

How do you make hydrogen and oxygen gas?

In a familiar high-school chemistry demonstration, an instructor first uses electricity to split liquid water into its constituent gases, hydrogen and oxygen. Then, by combining the two gases and igniting them with a spark, the instructor changes the gases back into water with a loud pop.

What happens when hydrogen gas and oxygen gas are mixed together?

Given the energetics presented above, there is a strong thermochemical bias for the production of water over hydrogen peroxide when H 2 and O 2 are reacted together. For instance, when hydrogen gas is burned in the presence of oxygen, a large amount of energy is released and water is produced as the major product.
