You get H2O, also known as water, by chemically combining hydrogen and oxygen.
The Chemical Reaction for Water Formation
The specific reaction for creating water involves hydrogen and oxygen molecules in a process that also releases energy. The balanced chemical equation is:
2H₂ + O₂ → 2H₂O + Energy
This means two molecules of diatomic hydrogen (H₂) react with one molecule of diatomic oxygen (O₂) to form two molecules of water (H₂O).
Breakdown of the Process:
- Reactants: The starting materials are diatomic hydrogen (H₂) and diatomic oxygen (O₂).
- Diatomic hydrogen means two hydrogen atoms are bonded together.
- Diatomic oxygen means two oxygen atoms are bonded together.
- Process: Hydrogen and oxygen atoms combine to form water molecules.
- Products: The main product is water (H₂O).
- Energy: The reaction also releases energy, which is often in the form of heat and light.
Practical Considerations
While the chemical reaction is fundamental, in practice, water is often obtained from readily available sources rather than directly combining hydrogen and oxygen due to the explosive nature of this reaction:
- Natural Sources: Most water we use comes from natural sources like rivers, lakes, groundwater, and rainwater.
- Purification: The water obtained is often purified to remove contaminants.
- Industrial Production: In specialized industrial settings, water can be produced from hydrogen and oxygen for specific applications, often involving controlled combustion.
