Select all that apply to physical and chemical properties. the various components of a mixture do not combine chemically. chemical properties can only be observed during a chemical reaction. the rusting of iron is a chemical reaction. melting and boiling points are physical properties. mass and volume are chemical properties.

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.
