Step-by-step explanation:

Answer 2

Step-by-step explanation:

A property that does no change the chemical composition of a substance are known as physical properties.

For example, mass, volume, size etc are all physical properties.

Whereas a property that changes the chemical composition of a substance are known as chemical properties.

For example, reactivity, toxicity etc are all chemical properties.

Therefore, identifying the given statements as follows.

• The various components of a mixture do not combine chemically - physical property.

• Chemical properties can only be observed during a chemical reaction - chemical property.

• The rusting of iron is a chemical reaction - chemical property.

• Melting and boiling points are physical properties - physical property.
