Exothermic reactions:
- If "chemical reactions" release energy into their surroundings, it is called as exothermic reactions.
- In this reaction, the temperature increases during the progress of the reaction.
- Reactants enthalpy is higher than the products.
- Enthalpy change is negative.
Endothermic reactions:
- If the chemical reactions absorb the heat energy from their surroundings, it is called exothermic reactions.
- In this reaction, the temperature will decrease during the progress of reactions.
- Reactants enthalpy is lower than the products.
- Enthalpy change is positive."

Let the breadth of the rectangular mango grove be x m
So, length = ‘2’ m
According to question,
Area = 800
⇒ 2x(x) = 800
⇒ 2x2 = 800
⇒ x2 = 400
⇒ x2 – 400 = 0
⇒ x2 + 0x – 400 = 0
Here, a = 1, b = 0, c = – 400
D = b2 – 4ac
= 0 – 4(1) (–400)
= 1600
So, the given quadratic equation has real roots (∵ D > 0) and hence it is possible to design rectangular mango grove.
Now, solving the quadratic equation x2 + 0x – 400 = 0, by quadratic formula, we get,
∵ 
is not possible
So, 
Hence, breadth of the rectangular mango grove is 20 m and length is 40 m.

Disguised unemployment is a kind of unemployment in which there are people who are visibly employed but are actually unemployed. This situation is also known as 'hidden unemployment'. In such a situation more people are engaged in a work than required. For example:
1. In rural areas, this type of unemployment is generally found in agricultural sector like - in a family of 9 people all are engaged in the same agricultural plot. But if 4 people are withdrawn from it there will be no reduction in output. So, these 4 people are actually facing disguised unemployment.
2. In urban areas, this type of unemployment can be seen mostly in service sectors such as in a family all members are engaged in one petty shop or a small business which can be managed by less number of persons.

- In a chemical reaction, the reactants are written on the left hand side and the products on the right hand side of the equation.
- An arrow (→) pointing towards the products is inserted between the reactants and the products. It also represents the direction of the reaction.
- A single arrow (→) indicates the direction in which the reaction proceeds.
- A double arrow (⥮) indicates a reversible reaction, i.e. the products recombine to form the reactants.
- A plus sign (+) is inserted between two or more reactants or products formed.
- If reactions are carried out under specific conditions of temperature, pressure, catalyst etc., then these conditions are mentioned on the arrow.
The chemical equation can be made more informative by mentioning the physical states of the reactants and products.
- If gas is liberated as a product then it is represented by an arrow pointing upwards (↑).
- If the product formed is in the form of a precipitate, it is represented by an arrow pointing downwards (↓).
