Hydrogen burns in oxygen to form water. The flame is almost colourless. Mixtures of hydrogen and oxygen (or hydrogen and air) can be explosive when the two gases are present in a particular ratio, so hydrogen must be handled very carefully. compound water
Hydrogen when brought to flame or burnt, it reacts with the oxygen present in the air to form the compound water. Therefore, we can conclude that when hydrogen burns in air, a chemical reaction takes place leading to the formation of the compound water. It is true that hydrogen is an explosive gas, and it also needs oxygen to burn.
In the First case:
In the First case:When hydrogen burns in oxygen, water is formed.
In the First case:When hydrogen burns in oxygen, water is formed.Hydrogen + Oxygen = Water
In the First case:When hydrogen burns in oxygen, water is formed.Hydrogen + Oxygen = Water2H2+O2→2H2O
In the First case:When hydrogen burns in oxygen, water is formed.Hydrogen + Oxygen = Water2H2+O2→2H2OWhen two reactants elements combine to form a single component, then this reaction is called the combination reaction. So, in this case, two reactants i.e. Hydrogen and oxygen combine to form a single product i.e. water molecules and heat is also released.

Here, a single reactant i.e. water, breaks or decomposes up to form two or more simple products i.e. hydrogen and oxygen. This decomposition reaction takes place by the action of electricity. So, we can see that in the first case, a combination reaction takes place and in the second case, a decomposition reaction takes place.
