Explanation:
A property that does not bring any change in chemical composition of a substance are known as physical properties.
For example, shape, size, mass, volume, density, hardness etc of a substance are all physical properties.
On the other hand, a property that changes chemical composition of a substance is known as chemical property.
For example, precipitation, reactivity, toxicity etc are chemical property.
Therefore, given descriptions are separated according to their physical and chemical properties as follows.
Physical properties:
- Zinc has a hardness on the Mohs scale of 2.5 and a density of 7.13 g/cm3 at .
- Zinc melts at .
Chemical properties:
- When zinc granules are added to dilute sulfuric acid, hydrogen is given off and the metal dissolves.
- It reacts slowly with oxygen gas at elevated temperatures to form zinc oxide, ZnO.
Benzene is more volatile.
