Reaction with Non-Metals
In this section, we focus on the chemical properties of hydrogen, particularly its reactions with non-metals. Hydrogen, being a unique element, interacts with various non-metals to form significant compounds:
- Reaction with Oxygen: When hydrogen burns in the presence of oxygen, it produces water (H₂O). This reaction is not only crucial for water production but also highly exothermic, releasing substantial energy.
The reaction can be summarized by the equation:
2H₂ + O₂ → 2H₂O
- Reaction with Chlorine: Another notable reaction is between hydrogen and chlorine, which yields hydrogen chloride (HCl). This gas is important in various industrial processes, including the production of hydrochloric acid.
The equation for this reaction is:
H₂ + Cl₂ → 2HCl
- Reaction with Nitrogen: Hydrogen also reacts with nitrogen to form ammonia (NH₃), primarily through the Haber process, which is essential for producing fertilizers. The reaction is depicted as follows:
N₂ + 3H₂ → 2NH₃
These reactions illustrate hydrogen's crucial role in synthesizing compounds necessary for life and industrial applications, emphasizing its reactivity and significance in chemical processes.

● With oxygen → water
Detailed Explanation
When hydrogen reacts with oxygen, it forms water (H₂O). This is a straightforward combination reaction where two molecules of hydrogen gas combine with one molecule of oxygen gas. The reaction is represented by the equation: 2H₂ + O₂ → 2H₂O. This reaction releases a significant amount of energy and is known as an exothermic reaction because heat is produced.
Examples & Analogies
Think of this reaction as a campfire where wood (representing hydrogen) burns in the oxygen from the air. Just as the fire creates heat and light, the reaction of hydrogen with oxygen produces water and releases energy.

● With chlorine → hydrogen chloride
Detailed Explanation
When hydrogen reacts with chlorine gas, it forms hydrogen chloride (HCl), a gas at room temperature that can dissolve in water to form hydrochloric acid. This reaction also occurs in a combination manner. The balanced chemical equation for this reaction is: H₂ + Cl₂ → 2HCl. This reaction is also exothermic, producing heat.
Examples & Analogies
This is like mixing baking soda (hydrogen) with vinegar (chlorine) - the two combine to produce carbon dioxide, which fizzes and releases gas. Hydrogen and chlorine react to produce a 'fizzy gas' (HCl), albeit with the release of energy that might not be visible.

● With nitrogen → ammonia
Detailed Explanation
Hydrogen reacts with nitrogen gas to produce ammonia (NH₃) in a reaction called the Haber process, which is essential for making fertilizers. The balanced chemical equation is: N₂ + 3H₂ → 2NH₃. This is another example of a combination reaction where two reactants combine to form a single product, ammonia. The reaction is significant because ammonia is a key ingredient in many fertilizers, contributing to food production.
Examples & Analogies
Imagine baking a cake (ammonia) using flour (nitrogen) and eggs (hydrogen). Just like how the ingredients combine to create a delicious cake, nitrogen and hydrogen combine under high temperatures and pressures to form ammonia, which is crucial for growing crops.
