How do you make water from hydrogen and oxygen?

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.

What happens when hydrogen reacts with oxygen?

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.

What reaction produces oxygen and water?

Water electrolysis Together with hydrogen (H2), oxygen is evolved by electrolysis of water.

Why is h2 O2 h2o not balanced?

The obtained result indicates that the oxygen atom is not equal on both sides. Thus the reaction is not balanced. The balanced reaction has the number of atoms involved in reaction in reactants as well as the product is equal.

What is the balanced equation of h2 O2?

2H2(g) + O2(g) → 2H2O(l ) Chemical equations give the following information about chemical reactions.

Why does oxygen and hydrogen 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).

Can we make oxygen out of water?

This is possible using a process known as electrolysis, which involves running a current through a water sample containing some soluble electrolyte. This breaks down the water into oxygen and hydrogen, which are released separately at the two electrodes.

What is symbol of oxygen and formula of oxygen?

The symbol of oxygen is O while the formula of oxygen is O2 as it exists in diatomic form in nature.

What is the reaction between oxygen and hydrogen?

Hydrogen molecules violently react with oxygen when the existing molecular bonds break and new bonds are formed between oxygen and hydrogen atoms. As the products of the reaction are at a lower energy level than the reactants, the result is an explosive release of energy and the production of water.

What happens when oxygen and hydrogen combine?

When molecular hydrogen (H 2) and oxygen (O 2) 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.

What elements react with oxygen?

Oxygen reacts rapidly with Group 1 elements. All alkali metal oxides form basic solutions when dissolved in water. When heated, lithium, sodium, potassium, rubidium, and cesium ignite through combustion reactions with oxygen.

What is the chemical equation for hydrogen and oxygen?

The balanced equation for hydrogen reacting with oxygen gas is: 2H2+ 02>>> 2H2O. 2 moles of Hydrogen reacts with 1 mole of Oxygen to give 2 moles of Water.
