Question

Several properties of water are shown. Classify each property as a PHYSICAL property or a CHEMICAL property.

Can be split into hydrogen and oxygen

Is liquid at room temperature

Has density of 1.0 g/cm^3

Reacts with certain metals

Answer 1

Splitting is chemical liquid at room temp is physical density is physical and reactions are chemical

Answer 2

Explanation:

A property which brings no change in chemical composition of a substance is known as a physical property.

For example, size, mass, density etc are physical property.

Whereas a property which brings change in chemical composition of a substance is known as a chemical property.

For example, reactivity, toxicity are chemical properties.

Therefore, classify the given properties as follows.

• Can be split into hydrogen and oxygen - chemical property.
• Is liquid at room temperature - physical property.
• Has density of 1.0 g/cm^3 - physical property.
• Reacts with certain metals - chemical property.
