Question

Which of the following even occurs when POP is mixed with water
A. Endothermic reaction
B. Displacement reaction
C. Exothermic reaction
D. Decomposition reaction

Answer 1

Which of the following even occurs when POP is mixed with water -

C) Exothermic reaction

Explanation:

• All chemical reactions involve energy. When chemicals are mixed together, they may react. There are two main types of reaction:

1. Exothermic Reaction
2. Endothermic Reaction

• Exothermic reactions are the reactions that proceed as soon as the components come into contact and give off energy (heat).

• Reaction of POP mixed with water -

The chemical equation for the reaction of Plaster of Paris and water can be represented as

$CaSO_{4}.\frac{1}{2}H_{2}O + \frac{3}{2}H_{2}O$ → $CaSO_{4}.2 H_{2}O$

• As Plaster of Paris reacts with water, heat is released through crystallization.

• Hence it can be termed as an Exothermic Reaction

Answer 2

When POP is mixed with water an Exothermic reaction takes place.

• POP reacts with water to liberate heat that is why it is an exothermic reaction.
• In Exothermic reactions, the heat is released and used in Endothermic reactions.
• In Displacement reactions, the exchange of elements takes place. It is of two types, Single Displacement, and Double Displacement reactions.
• In Decomposition reactions, the reactant gets divided into two or more elements to form the product.

C. Exothermic reaction is the correct answer.
