Concept explainers
(a)
Interpretation:
Whether the ductility of Titanium is a physical or chemical property is to be stated.
Concept introduction:
The change in the physical property of a substance is known as a physical change, which is reversible in nature.
The change in the chemical property of a substance is known as a chemical change, which is irreversible in nature.
(b)
Interpretation:
Whether the generation of gas by Zinc in acid is a physical or chemical property is to be stated.
Concept introduction:
Chemical reactions are the rearrangement of atoms, molecules, or ions to form other chemical substances. Chemical changes are of two types: physical change and chemical change.
The change in the physical property of a substance is known as a physical change, which is reversible in nature.
The change in the chemical property of a substance is known as a chemical change, which is irreversible in nature.
(c)
Interpretation:
Whether the ignition of yellow phosphorus in the air is a physical or chemical property is to be stated.
Concept introduction:
