Yogita Ingle 6 years, 9 months ago

Hybridization is defined as the mixing of the atomic orbitals belonging to the same atom but having slightly different energies so that a redistribution of energy takes place between them resulting in the formation of new orbitals of equal energies and identical shapes. The new orbitals thus formed are known as hybrid orbitals.
Hybridization of P in PCl₅ : sp³d

What is hookels law

Posted by Akash Singh 6 years, 9 months ago

CBSE > Class 11 > Chemistry

2 answers

Yogita Ingle 6 years, 9 months ago

Robert Hooke was the scientist who gave Hooke’s law.
Hooke’s law states that within the elastic limit, stress developed is directly proportional to the strain produced in a body.
Consider a scenario where we apply external force to the body. As a result stress develops in the body due to this stress there will be a strain produced in the body which implies that there will be some deformation in the body.
Because of stress, strain is produced.
According to Hooke’s law, if strain increases the stress will increase and vice-versa.
The Hooke’s law is applicable to all elastic substances.
It does not apply to plastic deformation.

What is a ribcage?

Posted by Sudhir Singh 6 years, 9 months ago

CBSE > Class 11 > Chemistry

1 answers

Yogita Ingle 6 years, 9 months ago

The rib cage is a bony and cartilaginous structure. A typical rib cage consists of 24 ribs (12 pairs), the sternum (an inverted T-shaped structure connecting the rib bones), costal cartilages and the 12 thoracic vertebrae shown in the diagram below. The first seven pairs of ribs connect directly to the sternum and are referred to as true ribs. The remaining five pairs of ribs do not connect directly to the sternum and are referred to as false ribs. The rib cage aids in the protection of the heart and lungs.
