Answer 1

Answer:

As you already know, the formation of water, electrolysis of water and processes such as respiration and digestion, are all chemical reactions. But, did you know that they are all different types of reactions? Some produce heat whereas some combine and give rise to a single product. Let’s go ahead and learn about the different types of reactions.

Types of Reactions

During a chemical reaction, atoms do not disappear from the mixture and appear elsewhere. Nor do they change from one element to atoms of another element. In fact, during chemical reactions, bonds between atoms are broken and re-made to give rise to new substances. Let’s understand how this happens in different types of reactions.

Combination Reaction

These are reactions where two or more reactants combine to give rise to a single product. For example, calcium oxide vigorously reacts with water to produce calcium hydroxide, also known as slaked lime. Slaked lime is used to whitewash walls.

CaO(s) + H2O(l) → Ca(OH)2(aq)

(Quicklime) → (Slaked lime)

Let’s look at some other examples of combination reactions –

Formation of water from hydrogen and oxygen.

2H2(g) + O2(g) → 2H2O(l)

Burning of coal.

C(s) + O2(g) → CO2(g)
