Under what conditions do hydrogen and oxygen 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. These two processes are represented by the two chemical equations shown at right.

How does hydrogen and oxygen form water?

A reaction between them requires energy to break the bonds between the atoms so they can form a new product. Once the bonds break, each hydrogen atom has a +1 positive charge, while each oxygen atom has a -2 negative charge. Two hydrogen atoms bound to one oxygen atom yield water, which is electrically neutral.

Can we form water from hydrogen and oxygen?

Just mixing hydrogen and oxygen together doesn’t make water – to join them together you need energy.

When H2 gas and O2 gas react to form water what happens to the atoms that were in the gases and what kind of bonds result?

When H2 gas and O2 gas react to form water, what happens to the atoms that were in the gases, and what kind of bonds result? The atoms in H2 gas and 02 gas are rearranged into water molecules. Covalent bonds are formed between the H and O atoms.

What happens when hydrogen combines with oxygen?

Textbook solution. When hydrogen combines with oxygen it gives water. In presence of electricity, the combination of hydrogen and oxygen produces heat and water as a side product.

How does hydrogen react with water?

Reaction of hydrogen with water Hydrogen does not react with water. It does, however, dissolve to the extent of about 0.00160 g kg-1 at 20°C (297 K) and 1 atmosphere pressure.

Why is water liquid when hydrogen and oxygen are gases?

Hydrogen the molecule (Hydrogen gas) has two Hydrogen atoms bonded together to form H2. Same deal for oxygen (gas = O2). When two water molecules come together, the slightly positive Hs are attracted to the negative O and they cluster together. This is (basically) why water is liquid at room temperature.

At what temperature does hydrogen and oxygen form water?

However, if the temperature of the hydrogen gas was very high (at least around 536°C), it would be able to spontaneously combine with oxygen in the air to form water. This is called autoignition – a process whereby a substance spontaneously ignites without any external flame or spark.

How does hydrogen react in water?

Hydrogen does not react with water. It does, however, dissolve to the extent of about 0.00160 g kg-1 at 20°C (297 K) and 1 atmosphere pressure.

When H2 and O2 react water vapor is produced what type of reaction is this?

Combustion Reactions
Combustion Reactions A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O2 as one reactant. The combustion of hydrogen gas produces water vapor.

How is water made from hydrogen gas and oxygen gas?

In theory, it’s easy to make water from hydrogen gasand 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.

What happens when you mix hydrogen and oxygen together?

Reacting hydrogen and oxygen is basically burning hydrogen gas, except rather than using the limited amount of oxygen in the air, you’re feeding the fire. During combustion, oxygen is added to a molecule, which produces water in this reaction.

Can hydrogen be used as a new source of energy?

(That’s why hydrogen is not a new energy source, just another way of carrying energy around.) Of course that also means that hydrogen is not a new source of water either. Converting water to hydrogen and oxygen and then letting them recombine is one way of purifying it, but probably one of the least efficient ways.

Why do hydrogen cations and oxygen anions react with each other?

The hydrogen cations and oxygen anions are then free to react with each other, which they do because of their electronegativity differences. When the chemical bonds re-form to make water, additional energy is released, which propagates the reaction.
