Question

Differentiate between combination, displacement and decomposition reaction. Make sure your answer is short and crip but informative

it is not on the internet

pls answer clearly and properly

thank you in advance

Answer 1

Answer:

1. combination reaction is a reaction in which two or more substances combine to form a single substance.

2. Displacement reaction is a reaction in which a higher reactive element displaces a lesser reactive element and takes its place.

3. Decomposition reaction is a reaction in which a single substance breaks down into two or more substances.

Answer 2

In a combination reaction, here the reactants combine to form the product.

In a decomposition reaction, here one of the reactants can form two or more products by the breakage of bonds.

Explanation:

Combination reaction,

• When two or more simple substances combine to form a more complex substance.it is called a combination reaction.
• Here when two or more reactants react and as a result product is formed
• It is another way to identify a combination reaction.
• For example, it is a combination of simple hydrogen gas and simple oxygen gas. It can produce  more complex material water!
• combination reaction is as shown:
• Reactant + Reactant ----- Product
• Example: 2H2 (g) + O2 (g) → 2H2O (l)

Decomposition reaction  

• In this type of decomposition reaction, When two or more complex substances are subjected to decompose into simpler components. The reactants give more than one product.
• Basically, the combination reaction and the decomposition reaction are opposite.
• For example, water can be broken down into hydrogen and oxygen gases. a decomposition reaction is as follows.
• reactant------ product + product

Example: 2FeSO4 (s) → heated Fe2O3 (s) + SO2 (g) + SO3 (g)
