Hydrogen and Oxygen Reaction - Hydrogen H2O
Hydrogen and Oxygen react together to form water (H2O). Water is a liquid at ambient conditions, but it often co-exists on Earth with its solid state, ice, and gaseous state, water vapor or steam. Both hydrogen and oxygen react with themselves to form the molecules H2 and O2 respectively. It takes two molecules of the diatomic hydrogen gas, combined with one molecule of the diatomic oxygen gas to produce two molecules of water. Water is a liquid at standard temperature and pressure. It is tasteless and odorless. Pure water has poor electrical conductivity, but this increases significantly with the dissolution of a small amount of ionic material such as sodium chloride. As an oxide of hydrogen, water is formed when hydrogen or its compounds burn or react with oxygen or its compounds. Water is a good solvent. Substances that dissolve in water are salts, sugars, acids, alkalis and some gases (oxygen, carbon dioxide) are called hydrophilic (water-loving) substances. Substances that do not mix well with water are fats and oils are called hydrophobic (water-fearing) substances. Water can be converted into Hydrogen and Oxygen through the process of Electrolysis.
Hydrogen Peroxide Reaction O2) is a clear, liquid, oxidizer commonly used as a bleach. Hydrogen peroxide decomposes (disproportionates) exothermically into water and oxygen gas spontaneously:
Hydrogen peroxide (H2
2 H2O2→ 2 H2O + O2
Distillation of hydrogen peroxide at normal pressures is highly dangerous because hydrogen peroxide can give off vapor that can detonate above 158 °F (50 °C) at normal atmospheric pressure. Low concentrations of hydrogen peroxide will chemically bleach many types of clothing it comes into contact with.
Hydrogen Sulfide Reaction S) is a colorless, very poisonous, flammable gas with the foul stench of rotten eggs. It acts as a reducing agent and is explosive. Hydrogen sulfide and oxygen burn with a blue flame to form sulfur dioxide (SO2) and water. Hydrogen sulfide (H2S) is slightly soluble in water and acts as a weak acid, it reacts with metal ions to form metal sulfides. Lead(II) acetate paper is used to detect hydrogen sulfide (H2S) because it turns grey in the presence of the gas as lead(II) sulfide is produced.
Hydrogen sulfide (H2
Hydrogen and Nitrogen Reaction) or ammonium (NH4) is formed. Ammonia is a colourless pungent gas which is lighter than air and very soluble in water which is used mainly to produce nitrogenous fertilizers, nitric acid, and some explosives. Ammonium compounds can occur in the vapor phase. When ammonia vapor comes in contact with hydrogen chloride vapor, a white cloud of ammonium chloride forms, which eventually settles out as a solid in a thin white layer on surfaces.
When Hydrogen is mixed with Nitrogen either ammonia (NH3
Some examples of a chemical reaction include most commonly burning, fermentation, tarnishing and rusting. There are several different types of Chemical reaction which have been detailed below:
- Substitution reactions
- Double displacement reactions
- Acid-base reactions
- Combustion reactions
- Combination reactions
- Decomposition reactions
